背景信息

**Background of MYH1 Recombinant Protein**

The MYH1 gene encodes myosin heavy chain 1. a critical component of skeletal muscle myosin, a molecular motor essential for muscle contraction. As part of the myosin II family, MYH1 forms the core of thick filaments in striated muscle, interacting with actin to generate force through ATP hydrolysis. Its structure includes an N-terminal motor domain (responsible for ATPase activity and actin binding), a neck region with light-chain-binding sites for force modulation, and a C-terminal tail mediating filament assembly.

MYH1 is predominantly expressed in fast-twitch skeletal muscle fibers, influencing contractile speed and metabolic efficiency. Mutations in MYH1 are linked to myopathies and cardiomyopathies, driving research into its role in disease. Recombinant MYH1 protein, produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), enables mechanistic studies without native tissue limitations. Production involves cloning the MYH1 cDNA into expression vectors, optimizing conditions for solubility, and purifying using affinity chromatography or tag-based methods.

Applications include *in vitro* studies of muscle contraction, drug screening for neuromuscular disorders, structural analysis (e.g., cryo-EM), and exploring MYH1 mutations' pathological impacts. Challenges persist in expressing full-length MYH1 due to its large size (~220 kDa) and post-translational modifications. Nonetheless, recombinant MYH1 remains vital for advancing muscle biology and therapeutic development.
