MYH1 (myosin heavy chain 1) is a protein encoded by the MYH1 gene and belongs to the myosin heavy chain family, which plays a critical role in muscle contraction by interacting with actin filaments. Expressed predominantly in fast-twitch skeletal muscle fibers, MYH1 is essential for generating mechanical force during rapid, high-intensity movements. Antibodies targeting MYH1 are widely used in research to study muscle physiology, fiber-type composition, and disorders affecting skeletal muscle, such as congenital myopathies, muscular dystrophies, or sarcopenia.

In clinical contexts, MYH1 antibodies have been investigated as potential biomarkers. For instance, autoimmune myositis patients may develop autoantibodies against MYH1. though these are less common compared to antibodies targeting other myositis-associated antigens. Additionally, MYH1 expression patterns are analyzed in cancer research, as abnormal myosin expression has been observed in certain tumors, potentially influencing metastasis or cell motility.

Commercially available MYH1 antibodies (polyclonal or monoclonal) are utilized in techniques like immunohistochemistry, Western blotting, and immunofluorescence. Their specificity and validation are crucial, given the high homology among myosin isoforms. Recent studies also explore MYH1's role in metabolic adaptations of muscle, highlighting its broader implications in exercise physiology and regenerative medicine. Overall, MYH1 antibodies serve as vital tools for dissecting muscle biology and disease mechanisms.
