MYLK (Myosin Light Chain Kinase): MYLK encodes an enzyme critical for smooth muscle contraction. It phosphorylates myosin light chains, facilitating the interaction between actin and myosin, and is vital in regulating vascular tone and blood pressure. MYLK is also involved in other smooth muscle functions such as gastrointestinal motility and respiratory airway resistance. Alterations in MYLK function or expression are implicated in various disorders including asthma, hypertension, and certain types of cancer....
