Method: Electron Microscopy, Resolution 8.3Å Resources: FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT Function TNNC1_PIG Troponin is the central regulatory protein of striated muscle contraction. Tn consists of three components: Tn-I which is the inhibitor of actomyosin ATPase, Tn-T which contains the binding site for tropomyosin and Tn-C. The binding of calcium to Tn-C abolishes the inhibitory action of Tn on actin filaments. See Also Actin 3D structures Tropomyosin 3D structures Troponin 3D structures
