Summary: Predicted to enable rhodopsin kinase activity. Acts upstream of or within several processes, including photoreceptor cell morphogenesis; positive regulation of phosphorylation; and post-embryonic retina morphogenesis in camera-type eye. Located in photoreceptor outer segment. Is expressed in retina outer nuclear layer. Used to study Oguchi disease-2. Human ortholog(s) of this gene implicated in Oguchi disease-2 and night blindness. Orthologous to human GRK1 (G protein-coupled receptor kinase 1). [provided by Alliance of Genome Resources, Apr 2022]

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.
