WebProtein phosphatases (PP) are divided into phosphoserine/threonine (Ser/Thr)-specific and phosphotyrosine (Tyr)-specific enzymes based on the distinct specificity toward the phosphorylated residues. Smooth muscle myosin is phosphorylated at Ser 19 (and sometimes Thr 18) at the N-terminal end of LC20. Thus, the Ser/Thr phosphatases are … WebThis phosphatase comprises three subunits: a 37-kDa phosphatase catalytic subunit, a 110- to 130-kDa myosin binding subunit (MBS)—also called myosin phosphatase target subunit (MYPT1)—and a 20-kDa subunit with unknown function. 88, 89 MBS is ubiquitously expressed with a relatively higher concentration in smooth muscle cells.
