Myosin phosphorylation
WebMay 23, 2024 · Myosin light chain kinase (MLCK) induces contraction of the perijunctional apical actomyosin ring in response to phosphorylation of the myosin light chain. Abnormal expression of MLCK has been observed in respiratory diseases, pancreatitis, cardiovascular diseases, cancer, and inflammatory bowel disease.

WebAug 7, 2024 · Myosin II activity is regulated by the Myosin II regulatory light chain subunit, whose phosphorylation converts Myosin II from an inactive form to an active form capable of filament assembly and ... 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 begin. First, the calcium will bind to calmodulin. After the influx of calcium ions and the binding to calmodulin, pp60 SRC (a protein kinase)causes a conformational change in MYLK, activating it and resulting in an increase in pho…
