About Crb2

Summary

Predicted to enable aspartic-type endopeptidase inhibitor activity. Involved in several processes, including embryonic morphogenesis; maintenance of epithelial cell apical/basal polarity; and photoreceptor cell maintenance. Located in several cellular components, including apical plasma membrane; apicolateral plasma membrane; and cell junction. Part of subapical complex. Is expressed in early conceptus and embryo. Used to study retinitis pigmentosa. Human ortholog(s) of this gene implicated in focal segmental glomerulosclerosis 9 and ventriculomegaly - cystic kidney disease. Orthologous to human CRB2 (crumbs cell polarity complex component 2). [provided by Alliance of Genome Resources, Apr 2022]
