MYO5A - myosin VA Gene
Also Known as GS1; MYO5; MYH12; MYR12
Species: Homo sapiens
About MYO5A
This gene has 51 transcripts (splice variants), 212 orthologues, 43 paralogues and is associated with 94 phenotypes. Broad expression in brain (RPKM 28.8), skin (RPKM 5.7) and 20 other tissues.
Summary
This gene is one of three Myosin V heavy-chain genes, belonging to the Myosin gene superfamily. Myosin V is a class of actin-based motor proteins involved in cytoplasmic vesicle transport and anchorage, spindle-pole alignment and mRNA translocation. The protein encoded by this gene is abundant in melanocytes and nerve cells. Mutations in this gene cause Griscelli syndrome type-1 (GS1), Griscelli syndrome type-3 (GS3) and neuroectodermal melanolysosomal disease, or Elejalde disease. Multiple alternatively spliced transcript variants encoding different isoforms have been reported, but the full-length nature of some variants has not been determined. [provided by RefSeq, Dec 2008]
