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). High levels of expression are found in small intestine, colon and skeletal muscle. Expression is low in organs composed mainly of smooth muscle, such as aorta, uterus and urinary bladder. No detectable expression is found in thymus, spleen, placenta and lymphocytes. 5 isoforms of the human protein are produced by alternative splicing.

Protein type: Motor protein; Motility/polarity/chemotaxis
SS: The number of records in which this modification site was determined using site-specific methods. SS methods include amino acid sequencing, site-directed mutagenesis, modification site-specific antibodies, specific MS strategies, etc.
