Function [MYO5A_HUMAN] Processive actin-based motor that can move in large steps approximating the 36-nm pseudo-repeat of the actin filament. 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. Publication Abstract from PubMed Myosin V (MyoV) motors have been implicated in the intracellular transport of diverse cargoes including vesicles, organelles, RNA-protein complexes and regulatory proteins. Here, we have solved the cargo-binding domain (CBD) structures of the three human MyoV paralogs (Va, Vb and Vc), revealing subtle structural changes that drive functional differentiation and a novel redox mechanism controlling the CBD dimerization process, which is unique for the MyoVc subclass. Moreover, the cargo- and motor-binding sites were structurally assigned indicating the conservation of residues involved in the recognition of adaptors for peroxisome transport and providing high-resolution insights into motor domain (MD) inhibition by CBD. These results contribute to understanding the structural requirements for cargo transport, auto-inhibition and regulatory mechanisms in myosin V motors.
