Disease
MYO5B_HUMAN Microvillous inclusion disease. The disease is caused by mutations affecting the gene represented in this entry.
Function
MYO5B_HUMAN May be involved in vesicular trafficking via its association with the CART complex. The CART complex is necessary for efficient transferrin receptor recycling but not for EGFR degradation. Required in a complex with RAB11A and RAB11FIP2 for the transport of NPC1L1 to the plasma membrane. Together with RAB11A participates in CFTR trafficking to the plasma membrane and TF (transferrin) recycling in nonpolarized cells. Together with RAB11A and RAB8A participates in epithelial cell polarization. Together with RAB25 regulates transcytosis (By similarity).[1] [2] [3]
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.
