[https://www.uniprot.org/uniprot/OPSD_BOVIN OPSD_BOVIN] Photoreceptor required for image-forming vision at low light intensity. Required for photoreceptor cell viability after birth. Light-induced isomerization of 11-cis to all-trans retinal triggers a conformational change leading to G-protein activation and release of all-trans retinal (By similarity).<ref>PMID:16908857</ref> <ref>PMID:17060607</ref>
