DESCRIPTION
Also known as MYO6_BOVIN, MYO6. Myosins are actin-based motor molecules with ATPase activity. Unconventional myosins serve in intracellular movements (By similarity). Myosin 6 is a reverse-direction motor protein that moves towards the minus-end of actin filaments (By similarity). Has slow rate of actin-activated ADP release due to weak ATP binding. Functions in a variety of intracellular processes such as vesicular membrane trafficking and cell migration (By similarity). Required for the structural integrity of the Golgi apparatus via the p53-dependent pro-survival pathway. Appears to be involved in a very early step of clathrin-mediated endocytosis in polarized epithelial cells (By similarity). May act as a regulator of F-actin dynamics (By similarity). As part of the DISP complex, may regulate the association of septins with actin and thereby regulate the actin cytoskeleton (By similarity). May play a role in transporting DAB2 from the plasma membrane to specific cellular targets (By similarity). May play a role in the extension and network organization of neurites (By similarity). Required for structural integrity of inner ear hair cells (By similarity). Modulates RNA polymerase II-dependent transcription (By similarity). Homodimer; dimerization seems to implicate the unfolding of the three-helix bundle region creating an additional calmodulin binding site, and cargo binding (By similarity). Able to function as a monomer under specific conditions in vitro (By similarity). Forms a complex with CFTR and DAB2 in the apical membrane of epithelial cells (By similarity). Component of the DISP/DOCK7-induced septin displacement complex, at least composed of DOCK7, LRCH3 and MYO6 (By similarity). Binding to calmodulin through a unique insert, not found in other myosins, located in the neck region between the motor domain and the IQ domain appears to contribute to the directionality reversal (By similarity). This interaction occurs only if the C-terminal lobe of calmodulin is occupied by calcium (By similarity). Interaction with F-actin/ACTN1 occurs only at the apical brush border domain of the proximal tubule cells (By similarity). Interacts with DAB2 (By similarity). In vitro, the C-terminal globular tail binds a C-terminal region of DAB2 (By similarity). Interacts with CFTR (By similarity). Interacts with OPTN (By similarity). Interacts with CABP5 (PubMed:22039235).
