Technical Data
Troponin I, Cardiac (cTnI, CMH7, Familial Hypertrophic Cardiomyopathy 7, MGC116817, TNNC1, Troponin I Type 3 Cardiac, TNNI3)
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 can not bind the actin in relaxed muscle. When Calcium binds to the Troponin C it causes certain confirmational changes which leads to dislocation of troponin I and finally tropomyosin leaves the the binding site for myosin on actin leading to contraction of muscle. The letter I is given due to its inhibitory character.

Suitable for use in Western Blot and Sandwich ELISA. Other applications not tested.
