This gene encodes an unconventional myosin. This protein differs from other myosins in that it has a long N-terminal extension preceding the conserved motor domain. Studies in mice suggest that this protein is necessary for actin organization in the hair cells of the cochlea. Mutations in this gene have been associated with profound, congenital, neurosensory, nonsyndromal deafness. This gene is located within the Smith-Magenis syndrome region on chromosome 17. Read-through transcripts containing an upstream gene and this gene have been identified, but they are not thought to encode a fusion protein. Several alternatively spliced transcript variants have been described, but their full length sequences have not been determined. [provided by RefSeq, Jul 2008]
MYO15A (Myosin XVA) is a Protein Coding gene. Diseases associated with MYO15A include Deafness, Autosomal Recessive 3 and Autosomal Recessive Non-Syndromic Sensorineural Deafness Type Dfnb. Among its related pathways are ERK Signaling and Sweet Taste Signaling. Gene Ontology (GO) annotations related to this gene include actin binding and motor activity. An important paralog of this gene is MYO7B.
