Involved with LARP6 in the stabilization of type I collagen mRNAs for CO1A1 and CO1A2. During cell spreading, plays an important role in cytoskeleton reorganization, focal contacts formation (in the central part but not the margins of spreading cells), and lamellipodial extension; this function is mechanically antagonized by MYH9 (By similarity). Cellular myosin that appears to play a role in cytokinesis, cell shape, and specialized functions such as secretion and capping. Myosin is a hexameric protein that consists of 2 heavy chain subunits (MHC), 2 alkali light chain subunits (MLC) and 2 regulatory light chain subunits (MLC-2). Interacts with PLEKHG6. Interacts with ECPAS (By similarity). Interacts with KIF26B (By similarity). Interacts with LARP6. Interacts with MCC. Interacts with CFAP95 (By similarity). Colocalizes with MCC at the leading edge of migrating cells. The rodlike tail sequence is highly repetitive, showing cycles of a 28-residue repeat pattern composed of 4 heptapeptides, characteristic for alpha-helical coiled coils. Phosphorylated by ABL2. Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Myosin family. Represents a conventional non-muscle myosin. This protein should not be confused with the unconventional myosin-10 (MYO10).
