MYH9: Cellular myosin that appears to play a role in cytokinesis, cell shape, and specialized functions such as secretion and capping. Interacts with PDLIM2. Interacts with SLC6A4. 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. Interacts with DDR1. Interacts with SVIL and HTRA3. In the kidney, expressed in the glomeruli. Also expressed in leukocytes. 2 isoforms of the human protein are produced by alternative splicing.
