Myosin light-chain kinase also known as MYLK or MLCK is a serine/threonine-specific protein kinase that phosphorylates a specific myosin light chain, namely, the regulatory light chain of myosin II. [3]
It has been well established that SM contraction is mainly regulated by phosphorylation of the myosin regulatory light chains (LC 20) by the 108-kD myosin light chain kinase (MLCK) . Increased expression of MLCK has been described in models of asthma and in human asthmatic airway SM ( 16 , 27 , 28 ).

MRLC phosphorylation in insulin signaling is mediated by Ca 2+ /calmodulin-dependent activation of myosin light chain kinase, 42 whereas MRLC Lactobacillusrhamnosus alleviates intestinal barrier dysfunction in partby increasingexpression ofzonula occludens-1 and myosin light-chain kinase in vivo.
Thus, myosin phosphatase undoes the muscle contraction process initiated by myosin light-chain kinase. The enzyme is composed of three subunits: the catalytic region (protein phosphatase 1, or PP1), the myosin binding subunit (MYPT1), and a third subunit (M20) of unknown function.

The kinase has low-affinity myosin and actin binding sites in Ig-like motifs at the N- and C-terminus, respectively.
MLCK or myosin light chain kinase is a muscle member of the immunoglobulin gene superfamily and is a calcium/calmodulin dependent protein kinase. MLCK is a regulatory protein for smooth muscle contraction, which acts by phosphorylating 20‐kDa myosin light chain (MLC20) to activate the myosin
DefinitionKontext. substantiv. (biochemistry) An abundant protein found in smooth muscle, identical to the C-terminus of myosin light-chain kinase.
MW 452.74, Purity > 99%. 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. Smooth muscle myosin light chain kinase is also phosphorylated, and recent results from experiments designed to satisfy the criteria Myosin light chain kinase (MLCK) is a serine/threonine kinase that belongs to CaM Kinases (Ca++/Calmodulin-dependent protein kinases) family.
