Target Information

Cardiac Troponin I (Cardiac-specific troponin I, TnI, Troponin I) is an integral inhibitory protein in cardiac muscle that exists as part of a complex with troponin C (TnC) and troponin T (TnT). The TnT subunit of troponin binds to tropomyosin to form a troponin–tropomyosin complex anchored in place by the binding of TnI to actin within muscle thin filaments. Structural changes resulting from calcium binding to specific sites on the regulatory TnC subunit release the inhibitory region of TnI from actin, enabling the attachment of myosin, allowing for muscle contraction and movement.

Measurement of blood TnI and TnT levels is an important diagnostic indicator of heart muscle damage and can differentiate between angina and myocardial infarction in patients with chest pain. Cardiac Troponin I has also been shown to inhibit angiogenesis in vivo and in vitro. Mutations in the Cardiac Troponin I gene cause familial hypertrophic cardiomyopathy type 7 (CMH7) and familial restrictive cardiomyopathy (RCM).
