MRLC2 non-sarcomeric myosin regulatory light chain 2. Binds calcium and plays an important role in regulation of both smooth muscle and nonmuscle cell contractile activity. Phosphorylation of MLC-2 in the presence of calcium and calmodulin increases the actin-activated myosin ATPase activity and thereby regulates the contractile activity. Myosin is an hexamer of 2 heavy chains and 4 light chains. Note: This description may include information from UniProtKB.
