Phosphorylation of Mammalian Myosin Light Chain Kinases
The phosphorylation of the calmodulin-dependent enzyme myosin light chain kinase, purified from bovine tracheal smooth muscle and human blood platelets, by the catalytic subunit of CAMP-dependent protein kinase and by cGMP-dependent protein kinase was investigated. When myosin light chain kinase which has calmodulin bound is phosphorylated by the catalytic subunit of CAMP-dependent protein kina...
متن کاملEffects of relaxin on rat uterine myosin light chain kinase activity and myosin light chain phosphorylation.
Isometrically suspended uteri from estrogen-primed rats were stimulated with prostaglandin F2 alpha and then exposed to relaxin. Relaxin-dependent decreases in the ratio of phosphorylated to total myosin light chains (MLC) and in MLC kinase activity, measured in the presence of 0.5 mg/ml of uterine myosin and the absence and presence of Ca2+-calmodulin (CaM), were observed. The time-course and ...
متن کاملMyosin light chain phosphorylation to the rescue.
A common cause of heart failure is hypertrophic cardiomyopathy (HCM) with a prevalence of at least 1 in 500 in adults (1); more recent data suggest that the prevalence of HCM may be as high as 1 in 200 (2). HCM is characterized by disorganized myocyte structure; formation of excess connective tissue (fibrosis); and, importantly, enlargement of cardiac myocytes that increases the ventricular wal...
متن کاملMyosin light chain kinase and myosin light chain phosphatase from Dictyostelium: effects of reversible phosphorylation on myosin structure and function
We have partially purified myosin light chain kinase (MLCK) and myosin light chain phosphatase (MLCP) from Dictyostelium discoideum. MLCK was purified 4,700-fold with a yield of approximately 1 mg from 350 g of cells. The enzyme is very acidic as suggested by its tight binding to DEAE. Dictyostelium MLCK has an apparent native molecular mass on HPLC G3000SW of approximately 30,000 D. Mg2+ is re...
