Tropomyosin alpha-3 chain, also known as TPM3, is member of the tropomyosin family of actin- binding proteins involved in the contractile system of striated and smooth muscles and the cytoskeleton of non- muscle cells. Tropomyosins are dimers of coiled-coil proteins that polymerize end-to-end along the major groove in most actin filaments. They provide stability to the filaments and regulate access of other actin-binding proteins. Mutations in this gene result in autosomal dominant nemaline myopathy, and oncogenes formed by chromosomal translocations involving this locus are associated with cancer.
