Summary: Enables retinal binding activity. Predicted to be involved in G protein-coupled receptor signaling pathway; cellular response to light stimulus; and phototransduction. Predicted to act upstream of or within signal transduction and visual perception. Predicted to be located in membrane. Predicted to be active in photoreceptor outer segment and plasma membrane. Is expressed in several structures, including endocrine system; eye; gut; heart; and integument. Orthologous to human OPN3 (opsin 3). [provided by Alliance of Genome Resources, Apr 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
