TPM1 (Tropomyosin 1) is a Protein Coding gene. Diseases associated with TPM1 include Cardiomyopathy, Hypertrophic, 3 and Cardiomyopathy, Dilated, 1E. Among its related pathways are Striated Muscle Contraction and Dilated cardiomyopathy (DCM). This gene is a member of the tropomyosin family of highly conserved, widely distributed actin-binding proteins involved in the contractile system of striated and smooth muscles and the cytoskeleton of non-muscle cells.where it also functions in association with the troponin complex to regulate the calcium-dependent interaction of actin and myosin during muscle contraction. In smooth muscle and non-muscle cells, alternatively spliced transcript variants encoding a range of isoforms have been described. Mutations in TPM1 are associated with type 3 familial hypertrophic cardiomyopathy.
