Summary: Predicted to enable calcium ion binding activity. Involved in post-embryonic retina morphogenesis in camera-type eye and visual perception. Acts upstream of with a positive effect on gene expression. Acts upstream of with a negative effect on protein localization. Acts upstream of or within several processes, including detection of light stimulus involved in visual perception; establishment of bipolar cell polarity involved in cell morphogenesis; and neurogenesis. Located in several cellular components, including adherens junction; microvillus; and photoreceptor outer segment. Part of subapical complex. Is active in apical part of cell. Is expressed in several structures, including alimentary system; central nervous system; epidermis; genitourinary system; and sensory organ. Used to study Leber congenital amaurosis 8 and retinitis pigmentosa 12. Human ortholog(s) of this gene implicated in pigmented paravenous chorioretinal atrophy and retinal disease (multiple). Orthologous to human CRB1 (crumbs cell polarity complex component 1). [provided by Alliance of Genome Resources, Dec 2024]

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.
