Summary

MYO5A (myosin VA, HGNC:7602) is a protein-coding gene on chromosome 15q21.2, encoding Unconventional myosin-Va (Q9Y4I1). Processive actin-based motor that can move in large steps approximating the 36-nm pseudo-repeat of the actin filament.

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) and neuroectodermal melanolysosomal disease, or Elejalde disease.

Function. Processive actin-based motor that can move in large steps approximating the 36-nm pseudo-repeat of the actin filament. Can hydrolyze ATP in the presence of actin, which is essential for its function as a motor protein. Involved in melanosome transport. Also mediates the transport of vesicles to the plasma membrane. May also be required for some polarization process involved in dendrite formation.

Subunit / interactions. May be a homodimer, which associates with multiple calmodulin or myosin light chains. Interacts with RIPL2, the interaction is required for its role in dendrite formation. Interacts with MLPH. Interacts with SYTL4. Interacts with MYRIP. Interacts with RAB10; mediates the transport to the plasma membrane of SLC2A4/GLUT4 storage vesicles. Interacts with FMR1; this interaction occurs in association with polyribosome.

Tissue specificity. Detected in melanocytes.

Disease relevance. Griscelli syndrome 1 (GS1) [MIM:214450] Rare autosomal recessive disorder that results in pigmentary dilution of the skin and hair, the presence of large clumps of pigment in hair shafts, silvery-gray hair and accumulation of melanosomes in melanocytes. GS1 patients show developmental delay, hypotonia and intellectual disability, without apparent immune abnormalities. The disease is caused by variants affecting the gene represented in this entry. Some patients who have MYO5A pathogenic variants and originally diagnosed with Griscelli syndrome 1 may rather have Elejalde syndrome.

Similarity. Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Myosin family.
