STRUCTURES OF THE APO AND CALCIUM TROPONIN-C REGULATORY DOMAINS: THE MUSCLE CONTRACTION SWITCHSTRUCTURES OF THE APO AND CALCIUM TROPONIN-C REGULATORY DOMAINS: THE MUSCLE CONTRACTION SWITCH
Structural highlights
1tnp is a 1 chain structure with sequence from Gallus gallus. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance.
TNNC2_CHICK 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.
