Summary: Enables actin filament binding activity; microfilament motor activity; and protein serine/threonine kinase activity. Involved in auditory receptor cell stereocilium organization; cochlea morphogenesis; and sensory perception of sound. Acts upstream of or within several processes, including positive regulation of filopodium assembly; protein phosphorylation; and regulation of actin filament length. Located in filopodium tip; photoreceptor inner segment; and stereocilium tip. Is expressed in cochlea and metanephros. Used to study autosomal recessive nonsyndromic deafness 30. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 30. Orthologous to human MYO3A (myosin IIIA). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

Results showed that Myo3a is essential for normal hearing by maintaining the intact structure of hair cell stereocilia, and the kinase domain plays a critical role in the normal functions of Myo3a.
Title: Knock-In Mice with Myo3a Y137C Mutation Displayed Progressive Hearing Loss and Hair Cell Degeneration in the Inner Ear.
results uncover the critical role that class III myosins play redundantly in hair-bundle morphogenesis
Title: Class III myosins shape the auditory hair bundles by limiting microvilli and stereocilia growth.
The phenotype of the Myo3a knockout mice parallels the phenotype of human DFNB30.

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.
