Since smooth muscle does not contain a troponin complex, as striated muscle does, this mechanism is the main pathway for regulating smooth muscle contraction. Reducing intracellular calcium concentration inactivates MLCK but does not stop smooth muscle contraction since the myosin light chain has … Meer weergeven 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. Meer weergeven While there are numerous differing domains depending on the cell type, there are several characteristic domains common amongst all MYLK isoforms. MYLK’s … Meer weergeven 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 … Meer weergeven Some pulmonary disorders have been found to arise due to an inability of MYLK to function properly in lung cells.
