Myosin-XV is a protein that in humans is encoded by the MYO15A gene.^[5][6]

Gene

Read-through transcript 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.^[6]

Function

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.^[6]

Clinical significance

Mutations in this gene have been associated with profound, congenital, neurosensory, nonsyndromic deafness.^[7] This gene is located within the Smith–Magenis syndrome region on chromosome 17.^[6]
