Description
Troponin I is a cardiac and skeletal muscle protein useful in the laboratory diagnosis of heart attack. Troponin I is a part of the troponin protein complex, where it binds to actin in thin myofilaments to hold the actin-tropomyosin complex in place. Because of it, myosin cannot bind actin in relaxed muscle. When calcium binds to the troponin C it causes conformational changes which lead to dislocation of troponin I and finally tropomyosin leaves the binding site for myosin on actin leading to contraction of muscle.

Human Diseases
- Myocardial Infarction (MI): Elevated levels indicate myocardial damage.
- Dilated Cardiomyopathy (DCM): Associated with anti-cardiac troponin I autoantibodies; prevalence ranges from 7.0% to 22.2%.
- Ischemic Cardiomyopathy (ICM): Elevated cTnI levels observed in patients.
- Peripartum Cardiomyopathy (PPCM): Increased troponin levels noted.
- Chagas Disease: cTnI levels can be elevated.
- Emery-Dreifuss Muscular Dystrophy (EDMD): Presence of autoantibodies against cTnI reported.
Cellular Signaling Pathways
- Calcium Signaling: cTnI plays a role in calcium-mediated muscle contraction by regulating the interaction between actin and myosin.
- PKA-mediated Phosphorylation: Phosphorylation of cTnI by Protein Kinase A affects cardiac contractility and relaxation.
- Inflammatory Responses: Involvement in immune responses, particularly in conditions like DCM where interleukin-10 responses are noted.
