Summary: Enables collagen binding activity; identical protein binding activity; and myosin binding activity. Involved in hair cell differentiation. Acts upstream of or within several processes, including establishment of protein localization; inner ear auditory receptor cell differentiation; and photoreceptor cell maintenance. Located in several cellular components, including periciliary membrane compartment; photoreceptor connecting cilium; and stereocilium membrane. Part of USH2 complex and stereocilia ankle link complex. Is expressed in sensory organ and testis. Used to study Usher syndrome type 2A. Human ortholog(s) of this gene implicated in Usher syndrome (multiple); nonsyndromic deafness; and retinitis pigmentosa (multiple). Orthologous to human USH2A (usherin).

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.
