TPM1 : ウィキペディア英語版
TPM1

Tropomyosin alpha-1 chain is a protein that in humans is encoded by the ''TPM1'' gene. This gene is a member of the tropomyosin (Tm) 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.
==Structure==
Tm is a 32.7 kDa protein composed of 284 amino acids. Tm is a flexible protein homodimer or heterodimer composed of two alpha-helical chains, which adopt a bent coiled coil conformation to wrap around the seven actin molecules in a functional unit of muscle. It is polymerized end to end along the two grooves of actin filaments and provides stability to the filaments. Human striated muscles express protein from the TPM1 (α-Tm), TPM2 (β-Tm) and TPM3 (γ-Tm) genes, with α-Tm being the predominant isoform in striated muscle. In human cardiac muscle the ratio of α-Tm to β-Tm is roughly 5:1.
