Troponin T binds to tropomyosin and helps position it on actin. And, in a less complicated light, troponin T modulates contraction of striated muscle 
Troponin T was discovered by the German physician Hugo A. Katus at the University of Heidelberg. He also developed the troponin T assay.
In patients with stable coronary artery disease, troponin T concentrations have been found to be significantly associated with the incidence of cardiovascular death and heart failure, but not with myocardial infarction.
