CC -!- FUNCTION: In hippocampal neurons it induces the formation of CC dendritic filopodia by trafficking the actin-remodeling protein CC VASP to the tips of filopodia, where it promotes actin elongation CC (By similarity). Myosins are actin-based motor molecules with CC ATPase activity. Unconventional myosins serve in intracellular CC movements. MYO10 binds to actin filaments and actin bundles and CC functions as plus end-directed motor. The tail domain binds to CC membranous compartments containing phosphatidylinositol 3,4,5- CC trisphosphate, which are then moved relative to actin filaments. CC Stimulates the formation and elongation of filopodia. Regulates CC cell shape, cell spreading and cell adhesion. Plays a role in CC formation of the podosome belt in osteoclasts. {ECO:0000250, CC ECO:0000269|PubMed:11457842, ECO:0000269|PubMed:15156152, CC ECO:0000269|PubMed:15705568, ECO:0000269|PubMed:16894163, CC ECO:0000269|PubMed:20081229, ECO:0000269|PubMed:20364131, CC ECO:0000269|PubMed:20392702, ECO:0000269|PubMed:20930142, CC ECO:0000269|PubMed:21666676}. CC -!- SUBUNIT: Monomer, when in an inactive confomation in the cytosol. CC Homodimer in its active, membrane-bound conformation; antiparallel CC coiled coil-mediated dimer formation. Interacts with ECM29. CC Interacts with NEO 1. Interacts with VASP. Interacts with DCC and CC ITGB5; the presence of DCC inhibits ITGB5 binding. Interacts with CC tubulin; ITGB5 or DCC binding inhibits tubulin binding. Interacts CC strongly with CALM3 and weakly with CALM, the CALM3 interaction is CC essential for function in filopodial extension and motility (By CC similarity). Interacts with ITGB1, ITGB3 and ITGB5. {ECO:0000250, CC ECO:0000269|PubMed:11457842, ECO:0000269|PubMed:15156152, CC ECO:0000269|PubMed:20364131, ECO:0000269|PubMed:21666676}. CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol. Cell projection, CC lamellipodium. Cell projection, ruffle. Cytoplasm, cytoskeleton. CC Cell projection, filopodium tip. Cytoplasm, cell cortex. Cell CC projection, filopodium membrane; Peripheral membrane protein. CC Note=May be in an inactive, monomeric conformation in the cytosol. CC Detected in cytoplasmic punctae and in cell projections. CC Colocalizes with actin fibers. Interacts with microtubules. CC Undergoes forward and rearward movements within filopodia. CC Interaction with membranes containing phosphatidylinositol 3,4,5- CC trisphosphate mediates localization at filopodium membranes. CC -!- TISSUE SPECIFICITY: Detected in kidney, testis, liver, kidney, CC cerebellum and brain cortex (at protein level). CC {ECO:0000269|PubMed:10984435}. CC -!- DOMAIN: Interaction between the motor domain and the tail leads to CC an inactive, monomeric conformation. Phospholipid binding via the CC PH domains leads to the formation of the active, dimeric form of CC the protein and strongly increases actin-dependent ATPase activity CC and motor activity. CC -!- DOMAIN: Interacts with membranes containing phosphatidylinositol- CC 3,4,5-trisphosphate via the PH domains. CC -!- DOMAIN: IQ 3 domain mediates high-affinity calcium-dependent CC binding to CALM3/CLP. {ECO:0000250}. CC -!- DOMAIN: The SAH (single alpha-helix) region is characterized by a CC high content of charged residues which are predicted to stabilize CC the alpha-helical structure by ionic bonds. It can refold after CC extension suggesting an in vivo force-dependent function. The CC isolated SAH domain is monomeric; however, in its distal part CC seems to form a semirigid helical structure which overlaps with a CC region shown to mediate antiparallel coiled coil-mediated CC dimerization (PubMed:25122759). {ECO:0000305|PubMed:25122759}. CC -!- SIMILARITY: Belongs to the TRAFAC class myosin-kinesin ATPase CC superfamily. Myosin family. {ECO:0000305}. CC -!- SIMILARITY: Contains 1 FERM domain. {ECO:0000255|PROSITE- CC ProRule:PRU00084}. CC -!- SIMILARITY: Contains 3 IQ domains. {ECO:0000255|PROSITE- CC ProRule:PRU00116}. CC -!- SIMILARITY: Contains 1 myosin motor domain. {ECO:0000305}. CC -!- SIMILARITY: Contains 1 MyTH4 domain. {ECO:0000255|PROSITE- CC ProRule:PRU00359}. CC -!- SIMILARITY: Contains 2 PH domains. {ECO:0000255|PROSITE- CC ProRule:PRU00145}. CC -!- CAUTION: Represents an unconventional myosin. This protein should CC not be confused with the conventional myosin-10 (MYH10). CC {ECO:0000305}. CC -!- CAUTION: Originally predicted to contain a coiled coil domain but CC shown to contain a stable SAH domain instead. {ECO:0000305}.
