Troponin, working in conjunction with tropomyosin, functions as a molecular switch, regulating muscle contraction in response to changes in the intracellular Ca2+ concentration. Troponin consists of three subunits, the Ca2+-binding subunit troponin C (TnC), the tropomyosin-binding subunit troponin T (TnT), and the inhibitory subunit troponin I (TnI). Troponin I binds to actin in thin myofilaments to hold the actin-tropomyosin complex in place, because of which myosin cannot bind to actin in relaxed muscle. When Calcium binds to the Troponin C it causes certain confomational changes which leads to dislocation of troponin I. The letter

Additional info: This antibody is reacting with free cardiac troponin I (cTnI) and cTnI forming complexes with other troponin components (In the presence of 5 mM EDTA). It is not affected by heparin, phosphorylation, oxidation and troponin complex formation.This antibody does not crossreact with skeletal muscle troponin I. Species Crossreactivity: Crossreacts with Rat, bovine, Cat, canine, Goat, porcine and Human. Does not crossreact with Fish or Rabbit.
