In diastole, the tropomyosin-troponin complex inhibits this interaction, and during systole the rise in intracellular calcium from sarcoplasmic reticulum binds to troponin C and induces a conformational change in the troponin-tropomyosin complex that disinhibits the actomyosin ATPase and permits contraction. [12]
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 difference is that the TnC subunit of troponin in skeletal muscle has four calcium ion-binding sites, whereas in cardiac muscle there are only three.
Blue = troponin C; green = troponic I; magenta = troponin T. [1] Troponin. Troponin I is a cardiac and skeletal muscle protein family. It is a part of the troponin protein complex, where it binds to actin in thin myofilaments to hold the actin-tropomyosin complex in place. Troponin I prevents myosin from binding to actin in relaxed muscle. When ...
Tropomyosin alpha-1 chain is a protein that in humans is encoded by the TPM1 gene. [5] This gene is a member of the tropomyosin (Tm) family of highly conserved, widely distributed actin-binding proteins involved in the contractile system of striated and smooth muscles and the cytoskeleton of non-muscle cells.

Cardiac muscle troponin T (cTnT) is a protein that in humans is encoded by the TNNT2 gene. [5] [6] Cardiac TnT is the tropomyosin-binding subunit of the troponin complex, which is located on the thin filament of striated muscles and regulates muscle contraction in response to alterations in intracellular calcium ion concentration.

Troponin T binds to tropomyosin and helps position it on actin, [2] and together with the rest of the troponin complex, modulates contraction of striated muscle. [3] The cardiac subtype of troponin T is especially useful in the laboratory diagnosis of heart attack because it is released into the blood-stream when damage to heart muscle occurs. [4]
