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.
