Myosin regulated photopeptide 9 (MYL9), also known as MLC2, belongs to the myosin regulatory subunit. Myosin is a structural component of muscles. MYL9 plays an important role in regulating smooth muscle and non muscle cell contractile activity through its phosphorylation of THR19 and SER20. Related to cytokines, receptor upper limits, and cell movement. It can bind to calcium and be activated by myosin light chain kinase. Some studies suggest that MYL9 may play an important role in various human cancers.
