Myosin, a structural component of muscle, consists of two heavy chains and four light chains.
This phosphorylation results in higher ATPase activity and the assembly of myosin II filaments.
The protein encoded by this gene is a myosin light chain that may regulate muscle contraction by modulating the ATPase activity of myosin heads.
Omecamtiv mecarbil (INN), previously codenamed CK-1827452, is a cardiac specific myosin activator.
