DESCRIPTION

Also known as MYH9_HUMAN, MYH9. Cellular myosin that appears to play a role in cytokinesis, cell shape, and specialized functions such as secretion and capping. Required for cortical actin clearance prior to oocyte exocytosis (By similarity). Promotes cell motility in conjunction with S100A4 (PubMed:16707441). During cell spreading, plays an important role in cytoskeleton reorganization, focal contact formation (in the margins but not the central part of spreading cells), and lamellipodial retraction; this function is mechanically antagonized by MYH10 (PubMed:20052411). 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 RASIP1 (By similarity). Interacts with DDR1 (By similarity). Interacts with PDLIM2 (By similarity). Interacts with SVIL (PubMed:12917436, PubMed:17925381). Interacts with HTRA3 (PubMed:22229724). Interacts with Myo7a (By similarity). Interacts with C9orf135 (PubMed:28345668). Interacts with LIMCH1; independently of the integration of MYH9 into the myosin complex (PubMed:28228547). Interacts with RAB3A (PubMed:27325790). Interacts with ZBED4 (PubMed:22693546). Interacts with S100A4; this interaction increases cell motility (PubMed:16707441).
