Troponin C is a protein which is part of the troponin complex. It contains four calcium-binding EF hands , although different isoforms may have fewer than four functional calcium-binding subdomains. It is a component of thin filaments , along with actin and tropomyosin .
Troponin activation. Troponin C (red) binds Ca2+, which stabilizes the activated state, where troponin I (yellow) is no longer bound to actin. Troponin T (blue) anchors the complex on tropomyosin. Troponin is found in both skeletal muscle and cardiac muscle, but the specific versions of troponin differ between types of muscle. The main ...

Test Sensitivity and specificity Approximate peak Description Troponin test: The most sensitive and specific test for myocardial damage. Because it has increased specificity compared with CK-MB, troponin is composed of 3 proteins- Troponin C, Cardic troponin I, and Cardiac troponin T. Troponin I especially has a high affinity for myocardial injury.
Troponin C, skeletal muscle is a protein that in humans is encoded by the TNNC2 gene. [ 5 ] [ 6 ] Troponin (Tn), is a key protein complex in the regulation of striated muscle contraction , composed of three subunits.
These calcium ions bind to a protein called troponin, which initiates the process of muscle contraction. [50] Calcium sensitizers function by binding to cardiac troponin C, thereby enhancing the sensitivity of heart muscle cells to naturally occurring calcium ions. [51]

This gene encodes an intracellular calcium-binding protein belonging to the troponin C superfamily. Members of this protein family have six EF-hand domains which bind calcium. This protein plays a role in diverse cellular functions, including message targeting and intracellular calcium buffering. [6]
