Myosin light-chain kinase
WebMyosin light chain kinase (MLCK) is a calcium/calmodulin-dependent enzyme (approx.160 kD). It is expressed in skeletal, cardiac, smooth and mammalian non-muscle cells. MLCK is encoded by the MYLK1 gene. This gene encodes telokin, non-muscle and the smooth muscle isoforms of MLCK.

Function. This gene, a muscle member of the immunoglobulin superfamily, encodes a myosin light-chain kinase, which is a calcium-/calmodulin-dependent enzyme.
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. See more While there are numerous differing domains depending on the cell type, there are several characteristic domains common amongst all MYLK isoforms. MYLK’s contain a catalytic core domain with an ATP binding … See more Four different MYLK isoforms exist: • MYLK1 – smooth muscle • MYLK2 – skeletal See more Protein kinase C and ROC Kinase are involved in regulating Calcium ion intake; these Calcium ions, in turn stimulate a MYLK, forcing a contraction. Rho kinase also modulates the activity of MYLK by downregulating the activity of MYLK's counterpart protein: … See more • protein kinase A See more These enzymes are important in the mechanism of contraction in muscle. Once there is an influx of calcium cations (Ca ) into the muscle, either from the sarcoplasmic reticulum or from the extracellular space, contraction of smooth muscle fibres may … See more Some pulmonary disorders have been found to arise due to an inability of MYLK to function properly in lung cells.

Myosin light chain 2 (MLC2), also known as myosin regulatory light chain (MRLC), RLC, or LC20, has many isoforms depending on its distribution. In smooth muscle, MLC2 is phosphorylated at Thr18 and Ser19 by myosin light chain kinase (MLCK) in ... neo bass speakersMyosin 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.
