MRLC2 Myosin regulatory subunit that plays an important role in regulation of both smooth muscle and nonmuscle cell contractile activity via its phosphorylation. Phosphorylation triggers actin polymerization in vascular smooth muscle. Implicated in cytokinesis, receptor capping, and cell locomotion. Ubiquitously expressed in various hematopoietic cells. Note: This description may include information from UniProtKB.
