Myosin light chain kinase phosphorylation
WebApr 7, 2004 · A similar mechanism occurs with nonmuscle myosin II with effects on many cellular actomyosin-dependent functions. The Ca 2+ -dependent phosphorylation of RLC is mediated by Ca 2+ /calmodulin (CaM)-dependent myosin light chain kinase (MLCK), whereas myosin light chain phosphatase dephosphorylates RLC. WebPhosphorylation of cardiac myosin heavy chains (see MYH7B, 609928) and light chains (see MYL2, 160781) by a kinase, such as MYLK3, potentiates the force and rate of cross …
