Tropomyosin alpha-3 chain (UniProt: Q63610; also known as Gamma-tropomyosin, Tropomyosin-3, Tropomyosin-5) is encoded by the Tpm3 (also known as Tpm-5, Tpm5) gene (Gene ID: 117557) in rat. The TPM3 gene codes for the slow-twitch skeletal muscle isoform ( s Tm) and at least 9 LMW cytoskeletal isoforms referred to as Tm5NM1 to Tm5NM11. Tropomyosins are dimers of coiled-coil proteins that provide stability to actin filaments and regulate access of other actin-binding proteins. In muscle cells, they regulate muscle contraction by controlling the binding of myosin heads to the actin filament. In non-muscle cells tropomyosins are implicated in stabilizing cytoskeleton actin filaments. Tropomyosins have been implicated in the pathogenesis of cancer where high molecular weight isoforms are consistently down-regulated in transformed cells, while malignant cells display an increased reliance on low molecular weight isoforms. Tropomyosin 3 is a homodimeric protein that can form heterodimers with a beta (TPM2) chain. Its coiled coil structure is formed by 2 polypeptide chains. (Ref.: Glass, JJ et al. (2015). BMC Cancer. 15; 712).
