MYH11

MYH11 (Myosin Heavy Chain 11): MYH11 encodes a smooth muscle myosin heavy chain, a key component of the contractile apparatus in smooth muscle cells. This protein plays a pivotal role in the contraction and relaxation of smooth muscle fibers, which is fundamental to various physiological processes, including vascular regulation, gastrointestinal motility, and respiratory function. MYH11 is essential for maintaining the structural integrity and function of smooth muscle tissues across the body. Mutations or dysregulation in the MYH11 gene can lead to a range of vascular disorders, including thoracic aortic aneurysms and dissections, highlighting its critical role in vascular health. The specific expression of MYH11 in smooth muscle cells also makes it a valuable marker for the differentiation of these cells and for studying the pathogenesis of smooth muscle-related diseases. Understanding the regulation and function of MYH11 is crucial for developing therapeutic strategies targeting smooth muscle dysfunction in various diseases.
