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 • Clayburgh DR, Rosen S, Witkowski ED, Wang F, Blair S, Dudek S, Garcia JG, Alverdy JC, Turner JR (December 2004). "A differentiation-dependent splice variant of myosin light chain kinase, MLCK1, regulates epithelial tight junction permeability" 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, … See more Some pulmonary disorders have been found to arise due to an inability of MYLK to function properly in lung cells.
