The MYO5A gene is one of three myosin V heavy-chain genes, belonging to the myosin gene superfamily. The MYO5A protein functions as a processive actin-based motor that can move in large steps approximating the 36-nm pseudo-repeat of the actin filament. MYO5A is also involved in cytoplasmic vesicle transport and anchorage, spindle-pole alignment and mRNA translocation. Different isoforms, encoded by alternatively spliced transcript variants, have been reported.
