function:Myosins are actin-based motor molecules with ATPase activity. Unconventional myosins serve in intracellular movements. Their highly divergent tails are presumed to bind to membranous compartments, which would be moved relative to actin filaments (By similarity). Plays a role in regions of dynamic actin.,similarity:Contains 1 FERM domain.,similarity:Contains 1 myosin head-like domain.,similarity:Contains 1 MyTH4 domain.,similarity:Contains 2 PH domains.,similarity:Contains 3 IQ domains.,
Cytoplasm, cytosol . Cell projection, lamellipodium . Cell projection, ruffle . Cytoplasm, cytoskeleton . Cell projection, filopodium tip . Cytoplasm, cell cortex . Cell projection, filopodium membrane ; Peripheral membrane protein . May be in an inactive, monomeric conformation in the cytosol. Detected in cytoplasmic punctae and in cell projections. Colocalizes with actin fibers. Undergoes forward and rearward movements within filopodia. Interacts with microtubules.
Ubiquitous.
