Post-translational modificationi

Phosphorylated by CIT (Rho-associated kinase) and by ROCK2 on serine and threonine residues. Phosphorylation at Thr-695 leads to inhibition of myosin phosphatase activity. Phosphorylation at Thr-850 abolishes myosin binding. May be phosphorylated at Thr-695 by DMPK; may inhibit the myosin phosphatase activity.3 Publications
