Supplementary information

Smooth muscle Myosin heavy chain 11 also known as MYH11 or myosin 11 is a protein that plays a mechanical role in muscle contraction. It forms part of the thick filament in smooth muscle cells. MYH11 has a molecular mass of approximately 227 kDa and is expressed in smooth muscle tissues including the walls of blood vessels the gastrointestinal tract and the respiratory system. As a member of the myosin heavy chain family it functions by interacting with actin filaments to facilitate contraction allowing for the maintenance and regulation of vascular tone and organ motility.
Biological function summary

Smooth muscle Myosin heavy chain 11 contributes to muscle function through its role within myofilament complexes. These complexes enable cells to achieve the force generation necessary for muscle contraction. MYH11 is critical to cytoskeletal maintenance and cell movement especially in the smooth muscles that line the visceral organs and blood vessels. Without proper functioning of MYH11 cells may lose structural stability and functionality leading to impaired muscle contraction and vessel elasticity.

Pathways

Smooth muscle Myosin heavy chain 11 engages intimately with signal transduction processes governing muscle contraction and relaxation. MYH11 acts in the RhoA/ROCK signaling pathway which is vital to the regulation of vascular smooth muscle contraction. Within this pathway MYH11 influences the activity of proteins like myosin light chain kinase and phosphatase. The protein also plays a role in actin-myosin complex dynamics through its interaction with cellular elements such as tropomyosin and caldesmon significantly impacting cellular processes like cell proliferation and migration.

Smooth muscle Myosin heavy chain 11 has significant correlations with conditions such as familial thoracic aortic aneurysm and aortic dissection types. Mutations or dysfunctions in MYH11 have a direct impact on the integrity of the aortic wall which can lead to these severe vascular conditions. Additionally MYH11 has associations with hypertension through its involvement in vascular tension regulation. The protein's malfunction may disturb its interactions with other myosin heavy chain family members exacerbating vascular risk factors.
