Protein-coding gene in the species Homo sapiens
Unconventional myosin-XV is a protein that in humans is encoded by the MYO15A gene .[ 5] [ 6]
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]
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 [ edit ] Mutations in this gene have been associated with profound, congenital , neurosensory , nonsyndromic deafness .[ 7] Smith–Magenis syndrome region on chromosome 17.[ 6]
