DESCRIPTION

Also known as MYO10_HUMAN, MYO10, KIAA0799. Myosins are actin-based motor molecules with ATPase activity. Unconventional myosins serve in intracellular movements. MYO10 binds to actin filaments and actin bundles and functions as plus end-directed motor. The tail domain binds to membranous compartments containing phosphatidylinositol 3, 4, 5-trisphosphate or integrins, and mediates cargo transport along actin filaments. Regulates cell shape, cell spreading and cell adhesion. Stimulates the formation and elongation of filopodia. May play a role in neurite outgrowth and axon guidance. In hippocampal neurons it induces the formation of dendritic filopodia by trafficking the actin-remodeling protein VASP to the tips of filopodia, where it promotes actin elongation. Plays a role in formation of the podosome belt in osteoclasts., Functions as a dominant-negative regulator of isoform 1, suppressing its filopodia-inducing and axon outgrowth-promoting activities. In hippocampal neurons, it increases VASP retention in spine heads to induce spine formation and spine head expansion (By similarity). Monomer, when in an inactive confomation in the cytosol. Homodimer in its active, membrane-bound conformation; antiparallel coiled coil-mediated dimer formation. Interacts strongly with CALM3 and weakly with CALM, the CALM3 interaction is essential for function in filopodial extension and motility. Interacts with ECPAS. Interacts with NEO1. Interacts with ITGB1 and ITGB3. Interacts with VASP (By similarity). Interacts with DCC and ITGB5; the presence of DCC inhibits ITGB5 binding. Interacts with tubulin; ITGB5 or DCC binding inhibits tubulin binding.
