The troponin complex is responsible for coupling the sarcomere contraction cycle to variations in intracellular calcium concentration. Increased cardiac troponin T (cTnT) levels after an episode of chest pain might indicate myocardial infarction. It was discovered by the German physician Hugo A. Katus at
