      DescriptionAnti-Tropomyosin-1 Antibody, clone 7F8B8
      Alternate Names
      • Tropomyosin alpha-1 chain
      • Alpha-tropomyosin
      • Tropomyosin-1
      Background InformationTropomyosin alpha-1 chain (UniProt: P09493; also known as Alpha-tropomyosin, Tropomyosin-1) is encoded by the TPM1 (also known as C15orf13, TMSA) gene (Gene ID: 7168) in human. Tropomyosin-1 is a cytoskeletal protein that associates with F-actin stress fibers. It binds to actin filaments in muscle and non-muscle cells and plays a central role, in association with the troponin complex, in the calcium dependent regulation of vertebrate striated muscle contraction. It stabilizes actin filaments and regulates the interaction of actin filament with other actin-binding proteins. In non-muscle cells is implicated in stabilizing cytoskeleton actin filaments. Tropomyosin-1 is a homodimeric protein, but can form heterodimer of an alpha (TPM1, TPM3, or TPM4) and a beta (TPM2) chain. Mutations in TPM1 gene have been linked to cardiomyopathy characterized by ventricular hypertrophy and ventricular dilation and impaired systolic function that results in congestive heart failure and arrhythmia. Ten different isoforms of Tropomyosin-1 have been described that are produced by alternative splicing.
