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 • MYLK3 – cardiac • MYLK4 – novel See more Some pulmonary disorders have been found to arise due to an inability of MYLK to function properly in lung cells. Over-activity in MYLK creates an imbalance in mechanical forces between adjacent endothelial and lung tissue cells.
