Background Troponin I (TnI) troponin T (TnT) and troponin C (TnC) form the troponin complex of thin filaments of striated muscle. TnI acts as the inhibitory subunit by blocking actin-myosin interactions and thereby mediating striated muscle relaxation. The TnI subfamily consists of 3 genes: TnI- skeletal-fast-twitch, TnI-skeletal-slow- twitch, and TnI-cardiac. The TNNI3 gene encodes the TnI-cardiac protein and is exclusively expressed in cardiac muscle tissue. Mutations in the TNNI3 gene cause familial hypertrophic cardiomyopathy type 7 and familial restrictive cardiomyopathy.

Biological Function Troponin I is the inhibitory subunit of troponin, the thin filament regulatory complex which confers calcium-sensitivity to striated muscle actomyosin ATPase activity.
