MYH7 Recombinant Rabbit mAb ,PBS Only (SDT-2936-44)

MYH7, the slow/cardiac β-myosin heavy chain encoded by the MYH7 gene on chromosome 14q12, is the dominant motor protein of the human ventricle and type I skeletal muscle fibers, forming the hexameric thick-filament complex (two MYH7, two ELC, two RLC) whose ATP-driven conformational cycles generate ≈2 pN of force at 5–10 nm steps; pathogenic missense or truncating variants disrupt this chemomechanical cycle and the accompanying α-helical coiled-coil packing, producing a dosage-sensitive spectrum of disease—hypertrophic and dilated cardiomyopathy, myosin storage myopathy, Laing distal myopathy—characterized by hypertrophic sarcomeres, replacement fibrosis, and progressive heart or skeletal muscle failure, while physiologically MYH7 expression is induced by thyroid hormone, exercise, and β-adrenergic signaling that up-regulate slow oxidative programs, making the protein a central therapeutic target for small-molecule myosin inhibitors (mavacamten) and gene-editing strategies aimed at normalizing contractile kinetics and Ca²⁺ sensitivity.
