    Abstract

    Background

    Rhabdomeric photoreceptors of eyes in the terrestrial slug Limax are the typical invertebrate-type but unique in that three visual opsins (Gq-coupled rhodopsin, xenopsin, Opn5A) and one retinochrome, all belonging to different groups, are co-expressed. However, molecular properties including spectral sensitivity and G protein selectivity of any of them are not determined, which prevents us from understanding an advantage of multiplicity of opsin properties in a single rhabdomeric photoreceptor. To gain insight into the functional role of the co-expression of multiple opsin species in a photoreceptor, we investigated the molecular properties of the visual opsins in the present study.

    Results

    First, we found that the fourth member of visual opsins, Opn5B, is also co-expressed in the rhabdomere of the photoreceptor together with previously identified three opsins. The photoreceptors were also demonstrated to express Gq and Go alpha subunits. We then determined the spectral sensitivity of the four visual opsins using biochemical and spectroscopic methods. Gq-coupled rhodopsin and xenopsin exhibit maximum sensitivity at ~ 456 and 475 nm, respectively, and Opn5A and Opn5B exhibit maximum sensitivity at ~ 500 and 470 nm, respectively, with significant UV sensitivity. Notably, in vitro experiments revealed that Go alpha was activated by all four visual opsins, in contrast to the specific activation of Gq alpha by Gq-coupled rhodopsin, suggesting that the eye photoreceptor of Limax uses complex G protein signaling pathways.

    Conclusions

    The eye photoreceptor in Limax expresses as many as four different visual opsin species belonging to three distinct classes. The combination of opsins with different spectral sensitivities and G protein selectivities may underlie physiological properties of the ocular photoreception, such as a shift in spectral sensitivity between dark- and light-adapted states. This may be allowed by adjustment of the relative contribution of the four opsins without neural networks, enabling a simple strategy for fine-tuning of vision.

    G-protein-coupled receptors (GPCRs) transmit signals into cells depending on the G protein type. To analyze the functions of GPCR signaling, we assessed the effectiveness of animal G-protein-coupled bistable rhodopsins that can be controlled into active and inactive states by light application using zebrafish. We expressed Gq- and Gi/o-coupled bistable rhodopsins in hindbrain reticulospinal V2a neurons, which are involved in locomotion, or in cardiomyocytes. Light stimulation of the reticulospinal V2a neurons expressing Gq-coupled spider Rh1 resulted in an increase in the intracellular Ca<sup>2+</sup> level and evoked swimming behavior. Light stimulation of cardiomyocytes expressing the Gi/o-coupled mosquito Opn3, pufferfish TMT opsin, or lamprey parapinopsin induced cardiac arrest, and the effect was suppressed by treatment with pertussis toxin or barium, suggesting that Gi/o-dependent regulation of inward-rectifier K<sup>+</sup> channels controls cardiac function. These data indicate that these rhodopsins are useful for optogenetic control of GPCR-mediated signaling in zebrafish neurons and cardiomyocytes.

    The position of the counterion in animal rhodopsins plays a crucial role in maintaining visible light sensitivity and facilitating the photoisomerization of their retinal chromophore. The counterion displacement is thought to be closely related to the evolution of rhodopsins, with different positions found in invertebrates and vertebrates. Interestingly, box jellyfish rhodopsin (JelRh) acquired the counterion in transmembrane 2 independently. This is a unique feature, as in most animal rhodopsins, the counterion is found in a different location. In this study, we used Fourier Transform Infrared spectroscopy to examine the structural changes that occur in the early photointermediate state of JelRh. We aimed to determine whether the photochemistry of JelRh is similar to that of other animal rhodopsins by comparing its spectra to those of vertebrate bovine rhodopsin (BovRh) and invertebrate squid rhodopsin (SquRh). We observed that the N-D stretching band of the retinal Schiff base was similar to that of BovRh, indicating the interaction between the Schiff base and the counterion is similar in both rhodopsins, despite their different counterion positions. Furthermore, we found that the chemical structure of the retinal in JelRh is similar to that in BovRh, including the changes in the hydrogen-out-of-plane band that indicates a retinal distortion. Overall, the protein conformational changes induced by the photoisomerization of JelRh yielded spectra that resemble an intermediate between BovRh and SquRh, suggesting a unique spectral property of JelRh, and making it the only animal rhodopsin with a counterion in TM2 and an ability to activate Gs protein.

    Animal visual rhodopsins can be classified into monostable and bistable rhodopsins, which are typically found in vertebrates and invertebrates, respectively. The former example is bovine rhodopsin (BovRh), whose structures and functions have been extensively studied. On the other hand, those of bistable rhodopsins are less known, despite their importance in optogenetics. Here, low-temperature Fourier-transform infrared (FTIR) spectroscopy was applied to jumping spider rhodopsin-1 (SpiRh1) at 77 K, and the obtained light-induced spectral changes were compared with those of squid rhodopsin (SquRh) and BovRh. Although chromophore distortion of the resting state monitored by HOOP vibrations is not distinctive between invertebrate and vertebrate rhodopsins, distortion of the all-trans chromophore after photoisomerization is unique for BovRh, and the distortion was localized at the center of the chromophore in SpiRh1 and SquRh. Highly conserved aspartate (D83 in BovRh) does not change the hydrogen-bonding environment in invertebrate rhodopsins. Thus, present FTIR analysis provides specific structural changes, leading to activation of invertebrate and vertebrate rhodopsins. On the other hand, the analysis of O-D stretching vibrations in D2O revealed unique features of protein-bound water molecules. Numbers of water bands in SpiRh1 and SquRh were less and more than those in BovRh. The X-ray crystal structure of SpiRh1 observed a bridged water molecule between the protonated Schiff base and its counterion (E194), but strongly hydrogen-bonded water molecules were never detected in SpiRh1, as well as SquRh and BovRh. Thus, absence of strongly hydrogen-bonded water molecules is substantial for animal rhodopsins, which is distinctive from microbial rhodopsins.

    Abstract

    Opsins, light-sensitive G protein-coupled receptors, have been identified in corals but their properties are largely unknown. Here, we identified six opsin genes (acropsins 1–6) from a coral species Acropora millepora, including three novel opsins (acropsins 4–6), and successfully characterized the properties of four out of the six acropsins. Acropsins 1 and 6 exhibited light-dependent cAMP increases in cultured cells, suggesting that the acropsins could light-dependently activate Gs-type G protein like the box jellyfish opsin from the same opsin group. Spectral sensitivity curves having the maximum sensitivities at ~ 472 nm and ~ 476 nm were estimated for acropsins 1 and 6, respectively, based on the light wavelength-dependent cAMP increases in these opsins-expressing cells (heterologous action spectroscopy). Acropsin 2 belonging to the same group as acropsins 1 and 6 did not induce light-dependent cAMP or Ca<sup>2+</sup> changes. We then successfully estimated the acropsin 2 spectral sensitivity curve having its maximum value at ~ 471 nm with its chimera mutant which possessed the third cytoplasmic loop of the Gs-coupled jellyfish opsin. Acropsin 4 categorized as another group light-dependently induced intracellular Ca<sup>2+</sup> increases but not cAMP changes. Our results uncovered that the Acropora coral possesses multiple opsins coupling two distinct cascades, cyclic nucleotide and Ca<sup>2+</sup>signaling light-dependently.

    Insect vision starts with light absorption by visual pigments based on opsins that drive Gq-type G protein-mediated phototransduction. Since Drosophila, the most studied insect in vision research, has only Gq-coupled opsins, the Gq-mediated phototransduction has been solely focused on insect vision for decades. However, genome projects on mosquitos uncovered non-canonical insect opsin genes, members of the Opn3 or c-opsin group composed of vertebrate and invertebrate non-visual opsins. Here, we report that a homologue of Opn3, MosOpn3 (Asop12) is expressed in eyes of a mosquito Anopheles stephensi. In situ hybridization analysis revealed that MosOpn3 is expressed in dorsal and ventral ommatidia, in which only R7 photoreceptor cells express MosOpn3. We also found that Asop9, a Gq-coupled visual opsin, exhibited co-localization with MosOpn3. Spectroscopic analysis revealed that Asop9 forms a blue-sensitive opsin-based pigment. Thus, the Gi/Go-coupled opsin MosOpn3, which forms a green-sensitive pigment, is co-localized with Asop9, a Gq-coupled opsin that forms a blue-sensitive visual pigment. Since these two opsin-based pigments trigger different phototransduction cascades, the R7 photoreceptors could generate complex photoresponses to blue to green light. This article is part of the theme issue 'Understanding colour vision: molecular, physiological, neuronal and behavioural studies in arthropods'.

    The taxon Elasmobranchii (sharks and rays) contains one of the long-established evolutionary lineages of vertebrates with a tantalizing collection of species occupying critical aquatic habitats. To overcome the current limitation in molecular resources, we launched the Squalomix Consortium in 2020 to promote a genome-wide array of molecular approaches, specifically targeting shark and ray species. Among the various bottlenecks in working with elasmobranchs are their elusiveness and low fecundity as well as the large and highly repetitive genomes. Their peculiar body fluid composition has also hindered the establishment of methods to perform routine cell culturing required for their karyotyping. In the Squalomix consortium, these obstacles are expected to be solved through a combination of in-house cytological techniques including karyotyping of cultured cells, chromatin preparation for Hi-C data acquisition, and high fidelity long-read sequencing. The resources and products obtained in this consortium, including genome and transcriptome sequences, a genome browser powered by JBrowse2 to visualize sequence alignments, and comprehensive matrices of gene expression profiles for selected species are accessible through https://github.com/Squalomix/info.

    <title>Abstract</title>Spectral tuning of visual pigments often facilitates adaptation to new environments, and it is intriguing to study the visual ecology of pelagic sharks with expanded habitats. The whale shark, which dives into the deep sea of nearly 2,000 meters besides near-surface filter-feeding, was previously shown to possesses the ‘blue-shifted’ rhodopsin (RHO). In this study, our spectroscopy of recombinant whale shark RHO mutants revealed the dominant effect of the novel spectral tuning amino acid site 94, which is implicated in congenital stationary night blindness of humans, accounting for the blue shift. Thermal decay profiling revealed the reduction of the thermal stability of whale shark RHO, as typically observed for cone opsins, which was experimentally shown to be achieved by the site 178, as well as 94. The results suggest that these two sites cooperatively enhance the visual capacity in both the deep sea and the sea surface, enabling exceptionally wide vertical migration of this species.

    BACKGROUND: Pineal-related organs in cyclostomes, teleosts, amphibians, and reptiles exhibit color opponency, generating antagonistic neural responses to different wavelengths of light and thereby sensory information about its "color". Our previous studies suggested that in zebrafish and iguana pineal-related organs, a single photoreceptor cell expressing both UV-sensitive parapinopsin and green-sensitive parietopsin generates color opponency in a "one-cell system." However, it remains unknown to what degree these opsins and the single cell-based mechanism in the pineal color opponency are conserved throughout non-mammalian vertebrates. RESULTS: We found that in the lamprey pineal organ, the two opsins are conserved but that, in contrast to the situation in other vertebrate pineal-related organs, they are expressed in separate photoreceptor cells. Intracellular electrophysiological recordings demonstrated that the parietopsin-expressing photoreceptor cells with Go-type G protein evoke a depolarizing response to visible light. Additionally, spectroscopic analyses revealed that parietopsin with 11-cis 3-dehydroretinal has an absorption maximum at ~570 nm, which is in approximate agreement with the wavelength (~560 nm) that produces the maximum rate of neural firing in pineal ganglion cells exposed to visible light. The vesicular glutamate transporter is localized at both the parietopsin- and parapinopsin-expressing photoreceptor terminals, suggesting that both types of photoreceptor cells use glutamate as a transmitter. Retrograde tracing of the pineal ganglion cells revealed that the terminal of the parietopsin-expressing cells is located close enough to form a neural connection with the ganglion cells, which is similar to our previous observation for the parapinopsin-expressing photoreceptor cells and the ganglion cells. In sum, our observations point to a "two-cell system" in which parietopsin and parapinopsin, expressed separately in two different types of photoreceptor cells,  contribute to the generation of color opponency in the pineal ganglion cells. CONCLUSION: Our results indicate that the jawless vertebrate, lamprey, employs a system for color opponency that differes from that described previously in jawed vertebrates. From a physiological viewpoint, we propose an evolutionary insight, the emergence of pineal "one-cell system" from the ancestral "multiple (two)-cell system," showing the opposite evolutionary direction to that of the ocular color opponency.

    Vision of sharks embraces various biological and ecological themes ranging from predation and adaptation to deep-sea life. However, behavioural and genetic studies have been limited by their elusive lifestyles, repeatedly reported declines of wild populations, and their unique life-history traits including low fecundity and enhanced longevity. Sharks have also not been actively studied on the cellular and molecular levels, because of additional difficulties in cell culture, tissue collection and genome sequencing. A recent study circumvented some of these obstacles by means of genome informatics thereby portrayed the variation of visual opsin gene repertoires among elasmobranchs (sharks and rays) and spectral shifts of the rhodopsin pigment. Comprehensive surveys in whole-genome sequences are also revealing the repertoires of nonvisual opsins with unknown functions. This review is aimed to summarize existing studies on shark opsins with an emphasis on genomic investigation of gene repertoires and to provide insights into the better understanding of underwater ecology of marine megafauna with in vitro experimentation.

    The velvet belly lanternshark, Etmopterus spinax, uses counterillumination to disappear in the surrounding blue light of its marine environment. This shark displays hormonally controlled bioluminescence in which melatonin (MT) and prolactin (PRL) trigger light emission, while α-melanocyte-stimulating hormone (α-MSH) and adrenocorticotropic hormone (ACTH) play an inhibitory role. The extraocular encephalopsin (Es-Opn3) was also hypothesized to act as a luminescence regulator. The majority of these compounds (MT, α-MSH, ACTH, opsin) are members of the rapid physiological colour change that regulates the pigment motion within chromatophores in metazoans. Interestingly, the lanternshark photophore comprises a specific iris-like structure (ILS), partially composed of melanophore-like cells, serving as a photophore shutter. Here, we investigated the role of (i) Es-Opn3 and (ii) actors involved in both MT and α-MSH/ACTH pathways on the shark bioluminescence and ILS cell pigment motions. Our results reveal the implication of Es-Opn3, MT, inositol triphosphate (IP3), intracellular calcium, calcium-dependent calmodulin and dynein in the ILS cell pigment aggregation. Conversely, our results highlighted the implication of the α-MSH/ACTH pathway, involving kinesin, in the dispersion of the ILS cell pigment. The lanternshark luminescence then appears to be controlled by the balanced bidirectional motion of ILS cell pigments within the photophore. This suggests a functional link between photoreception and photoemission in the photogenic tissue of lanternsharks and gives precious insights into the bioluminescence control of these organisms.

    In lower vertebrates, brain photoreceptor cells express vertebrate-specific non-visual opsins. We previously revealed that a pineal-related organ-specific opsin, parapinopsin, is UV-sensitive and allows pineal wavelength discrimination in lampreys and teleost. The Australian pouched lamprey was recently reported as having two parapinopsin-related genes. We demonstrate that a parapinopsin-like opsin from the Japanese river lamprey exhibits different molecular properties and distribution than parapinopsin. This opsin activates Gi-type G protein in a mammalian cell culture assay in a light-dependent manner. Heterologous action spectroscopy revealed that the opsin forms a violet to blue-sensitive pigment. Interestingly, the opsin is co-localised with green-sensitive P-opsin in the cells of the M5 nucleus of Schober (M5NS) in the mesencephalon of the river and brook lamprey. Some opsins-containing cells of the river lamprey have cilia and others an axon projecting to the retina. The opsins of the brook lamprey are co-localised in the cilia of centrifugal neurons projecting to the retina, suggesting that cells expressing the parapinopsin-like opsin and P-opsin are sensitive to violet to green light. Moreover, we found neural connections between M5NS cells expressing the opsins and the retina. These findings suggest that the retinal activity might be modulated by brain photoreception.

    Animal opsin-based pigments are light-activated G-protein-coupled receptors (GPCRs), which drive signal transduction cascades via G proteins. Thousands of animal opsins have been identified, and molecular phylogenetic and biochemical analyses have revealed that opsin-based pigments have basically diversified in selective activation of G proteins (Gs, Gq, Gi, Go, and transducin). Here, we discuss the optogenetic potentials of diverse animal opsins, particularly Gq-coupled spider opsin, Gs-coupled jellyfish opsin, and Gi/Go-coupled mosquito opsin 3 (Opn3). After absorbing light, these purified opsin-based pigments do not release the chromophore retinal, indicating the bleach-resistant nature of their photoproducts. In addition, unlike vertebrate visual opsin-based pigments that have been conventionally used for optogenetic applications, the stable photoproducts of spider opsin- and mosquito Opn3-based pigments revert to their original dark states upon subsequent light absorption, which indicates their photoregeneration ability. Mammalian cultured cells that express spider opsin exhibit light-induced increases in Ca&lt
    sup&gt
    2+&lt
    /sup&gt
    levels, and jellyfish opsin- and mosquito Opn3-expressing cells exhibit light-dependent increases and decreases in cyclic adenosine monophosphate (cAMP) levels, respectively. These findings indicate that these pigments control different second messengers, Ca&lt
    sup&gt
    2+&lt
    /sup&gt
    and cAMP, in mammalian cultured cells, suggesting that these bleach-resistant opsins have an optogenetic potential.

    Pineal and related organs are major extraocular photoreceptors in nonmammalian vertebrates. The pineal organ contains several types of photoreceptor cells, which contribute to regulating light-dependent melatonin secretion and the neural light response, including irradiance detection and wavelength discrimination. Visual opsins and pineal-specific opsins have been identified from the pineal and related organs in a wide variety of non-mammalian vertebrates. Pinopsin and parapinopsin are key opsins for understanding melatonin secretion in the chicken pineal organ and wavelength discrimination in the lamprey pineal organ, respectively. Interestingly, parapinopsin has the molecular characteristics of both vertebrate and invertebrate opsin-based pigments, making it an important photopigment for understanding the molecular evolution of vertebrate visual opsins. In this chapter, we discuss the opsin-based pigments functioning in the pineal and related organs with a focus on parapinopsin.

    Animals use light information not only for vision but for non-visual functions, such as circadian entrainment and pupillary light response. Opsins, underling molecules of these photoreceptions, are diversified. We aimed to reveal relationships between the diversity of opsins and that of photoreceptive systems by biochemical and spectroscopic analyses of varied opsins. We cloned seven opsins from amphioxus (<I>Branchiostoma belcheri</I>) and succeeded in functional expression of amphioxus homologues of the Go-coupled opsin and the perospin, whose molecular properties have been largely unknown, in HEK293 cells. Spectroscopic analyses revealed that the Go-coupled opsin and the peropsin bind 11-cis and all-trans retinals, respectively as a chromophore. The results strongly suggest that the physiological function of peropsin is a retinal photoisomerase, while 11-cis configuration is necessary for the Go-coupled opsin. We also demonstrated that the amphioxus homologue of melanopsin, which functions as the circadian photopigment in the photosensitive retinal ganglion cells in mammals, is considerably similar to invertebrate visual pigments in biochemical and photochemical properties for the first time. This finding suggested the evolutionary linkage between invertebrate rhabdomeric visual cells and vertebrate photosensitive retinal ganglion cells. We also showed that the parapinopsin is the UV pigment in the lamprey (<I>Lethenteron japonica</I>) pineal and is the bistable pigment having photointerconvertible two stable states, that is, the original and the G-protein-activating states. The bistable nature of the parapinopsin can account for the photorecovery of the pineal UV-sensitivity by background green light. Our approach could provide cues to understand the evolution of physiological functions.
