    Summary
    Predicted to enable calcium ion binding activity. Predicted to be involved in establishment or maintenance of epithelial cell apical/basal polarity and heterophilic cell-cell adhesion via plasma membrane cell adhesion molecules. Predicted to act upstream of with a positive effect on gene expression. Predicted to act upstream of with a negative effect on protein localization. Predicted to act upstream of or within several processes, including detection of light stimulus involved in visual perception; eye morphogenesis; and neurogenesis. Located in microvillus and photoreceptor inner segment. 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.
