Another source of smooth muscle disorders like ischemia–reperfusion, hypertension, and coronary artery disease arise when mutations to protein kinase C (PKC) result in excessive inhibition of MYLP, which counteracts the activity of MYLK by dephosphorylating myosin light chain. Because myosin light chain has no inherent phosphate cleaving ...
This gene, a muscle member of the immunoglobulin superfamily, encodes a myosin light-chain kinase, which is a calcium-/calmodulin-dependent enzyme.This kinase phosphorylates myosin regulatory light chains to facilitate myosin interaction with actin filaments to produce contractile activity.

When the light chains are phosphorylated, they become active and will allow contraction to occur. The enzyme that phosphorylates the light chains is called myosin light-chain kinase (MLCK), also called MLC 20 kinase. [8] In order to control contraction, MLCK will work only when the muscle is stimulated to contract.
Myosin regulatory light chain 2, ventricular/cardiac muscle isoform (MLC-2) also known as the regulatory light chain of myosin (RLC) is a protein that in humans is encoded by the MYL2 gene. [ 5 ] [ 6 ] This cardiac ventricular RLC isoform is distinct from that expressed in skeletal muscle ( MYLPF ), smooth muscle ( MYL12B ) and cardiac atrial ...
Myosin light chain kinase (MLCK) inhibitors are one of the few peptides that can cross the plasma membrane relatively quickly. Under stressful conditions, MLCK's in the human body promotes increased permeability of microvessels. It is thought that MLCK phosphorylates endothelial myosin, leading to cell contraction.
In the lung, cAMP decreases calcium concentrations within cells and activates protein kinase A. Both of these changes inactivate myosin light-chain kinase and activate myosin light-chain phosphatase. In addition, β 2 agonists open large conductance calcium-activated potassium channels and thereby tend to hyperpolarize airway smooth muscle ...
Myosin light chain kinase 4 also known as MYLK4 is an enzyme which in humans is encoded by the MYLK2 gene. [2] MYLK4 is a member of the myosin light-chain kinase family of serine/threonine-specific protein kinases that phosphorylate the regulatory light chain of myosin II .
