Summary: Predicted to enable myosin tail binding activity and spectrin binding activity. Involved in brush border assembly; protein localization to microvillus; and regulation of microvillus length. Acts upstream of or within several processes, including inner ear development; parallel actin filament bundle assembly; and sensory perception of sound. Located in several cellular components, including brush border; photoreceptor inner segment; and upper tip-link density. Is active in stereocilium. Is expressed in several structures, including alimentary system; cochlea; genitourinary system; heart; and lung epithelium. Used to study Usher syndrome type 1C and autosomal recessive nonsyndromic deafness 18A. Human ortholog(s) of this gene implicated in Usher syndrome; Usher syndrome type 1; Usher syndrome type 1C; and autosomal recessive nonsyndromic deafness 18A. Orthologous to human USH1C (USH1 protein network component harmonin). [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.
