WebThese findings suggest that myosin II activity is regulated temporally during mitosis, and the stimulation of myosin II motor activity by Ser 19 phosphorylation could provide the stimulus for the initiation of cytokinesis. 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: Myosin Light Chain Phosphatase (MYLP). In addition to … See more 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.
