anti- MYLK2 antibody

Background

Myosin light chain kinase 2 (MYLK2) is a muscle-specific isoform of myosin light chain kinase predominantly expressed in skeletal muscle tissue. MYLK2 plays a key role in regulating myosin activity during muscle contraction by phosphorylating the regulatory light chains of myosin II, a process critical for force generation and sarcomere function. The kinase activity of MYLK2 is tightly regulated by calcium-calmodulin signaling, ensuring precise control of contractile responses during dynamic skeletal muscle activities such as exercise and locomotion. MYLK2 also contributes to the adaptive remodeling of muscle fibers in response to mechanical stress and physiological demands. Mutations or dysregulation of MYLK2 have been associated with myopathies and muscle weakness, emphasizing its essential role in maintaining muscular integrity and function.
