More | myosin phosphatase is a complex that consists of a catalytic subunit protein phosphatase 1c, PP1cbeta, a large subunit myosin phosphatase targeting subunit, MYPT, and a small subunit. Stability of PP1cbeta and MYPT1 is interdependent, knocking down one of the subunits decreases the expression level of the other. MYPT1 binding is restricted to PP1cbeta, the central region of PP1cbeta confers the isoform-specific binding, while the variable, C-terminal domain of PP1cbeta is the region key for isoform-specific interaction with MYPT1.

additional information | myosin II association with actin, which triggers contraction, is regulated by orchestrated waves of phosphorylation/dephosphorylation of the myosin regulatory light chain. Dephosphorylation is mediated by myosin phosphatase | Homo sapiens |
