General description

Tropomyosin 1 (TPM1) is encoded by the gene mapped to human chromosome 15q22.2. The encoded protein belongs to the TPM protein family.


The antibody recognizes an epitope on skeletal and cardiac tropomyosin. The antibody shows no reaction with denatured protein by immunoblotting. No cross-reactivity has been observed with smooth muscle or non-muscle tropomyosin.


chicken muscle tropomyosin.

Biochem/physiol Actions

Tropomyosin 1 (TPM1) is a potent tumor suppressor gene. It is expressed at low levels in various types of solid cancers including, oral squamous cell carcinoma (OSCC) and tongue squamous cell carcinoma. Mutation in the gene is associated with the development of hypertrophic cardiomyopathy. The encoded protein is involved in the regulation of actin-myosin interaction in striated muscles. Tropomyosin plays an essential role in Ca2+ -regulated contraction of cardiac muscle.
