May 23, 2017 Myosin light chain kinase (MLCK) induces contraction of the perijunctional apical actomyosin ring in response to phosphorylation of the myosin

The enzyme is composed of three subunits: the The enzyme that phosphorylates the light chains is called myosin light-chain kinase (MLCK), also called MLC20 kinase. In order to control contraction, MLCK will Phosphorylation of both myosin heavy chain and myosin light chain (MLC) affects motor activity and thick filament assembly. In smooth muscle cells, Calcium ions enter the L-type Calcium channels under the stimulus and bind to calmodulin, which then leads to activation of myosin light chain kinase. Fig. 1.

Myosin light chain kinase

It phosphorylates the regulatory myosin light chains of * myosin II , in order to facilitate myosin binding to * actin and therefore aid contractility. Myosin light chain kinase (MLCK) is a Ca 2+ –CaM-dependent enzyme that phosphorylates MLC at Ser-19 or Ser-19/Thr-18 (Dudek and Garcia, 2001; Lazar and Garcia, 1999; Verin et al., 1998a,b; Wadgaonkar et al., 2003). This phosphorylation promotes actin–myosin cross-bridging that leads to cellular contraction. Myosin Light Chain Kinase. Isoforms of myosin light chain kinase (MLCK) exist in smooth and skeletal muscle and in other tissues including the brain. They all exist as monomers that can be quite variable in mass.

MLCK-dependent MLC phosphorylation increases the ATPase activity of the smooth muscle myosin, which leads to actin activation; this is followed by cyclic

Smooth muscle contraction is regulated by variations in intracellular [Ca2+]; increased levels activate the myosin light chain kinase (. Myosin Light Chain Kinase Inhibitor Peptide 18.

Den lätta 20 kD-kedjan fosforyleras snabbare än någon annan acceptor, men lätta kedjor från andra myosiner och myosin i sig kan agera acceptorer.

2017-10-20. Contents. 1 Structures Phosphorylation of the regulatory light chain of myosin by the Ca2+/calmodulin-dependent myosin light chain kinase plays an important role in smooth muscle contraction, nonmuscle cell shape changes, platelet contraction, secretion, and other cellular processes. On one hand, myosin light-chain kinase directly phosphorylates MLC at Thr-18 and/or Ser-19, resulting in MLC activation and actin-myosin binding. On the other hand, myosin-associated protein phosphatase dephosphory-lates MLC and thus counteracts the MLCK effect, leading to cell relaxation .

Potent and selective myosin light chain kinase inhibitor (MLCK) (Ki = 300 nM). Also inhibits PKA and PKC (Ki values are 21 and 42 μM, respectively). Phosphorylation of the regulatory light chain of myosin by the Ca2+/calmodulin-dependent myosin light chain kinase plays an important role in smooth muscle contraction, nonmuscle cell shape changes, platelet contraction, secretion, and other cellular processes.
