  10. Serial measurement of troponin I revealed a persistent elevation in patients with diabetes mellitus type 2.

  11. Plasma troponin C1 (cTnI) is biomarker of choice for diagnosing acute myocardial infarction (AMI) because of its high specificity as biomarker for damage to myocardial tissue. Data suggest the "best cut-off" for plasma cTnI is 0.014 micrograms/L in AMI.

  1. Pim-1 is a novel kinase that phosphorylates cTnI primarily at Ser23/24 and Ser150 in cardiomyocytes, which in turn may modulate myofilament function under a variety of physiological and pathophysiological conditions.

  2. Hyperphosphorylation of this serine199 in cTnI C terminus impacts heart function by depressing diastolic function at baseline and limiting systolic reserve under physiological stresses. Paradoxically, it preserves heart function after ischemia/reperfusion injury, potentially by decreasing proteolysis of cTnI.

  6. Combined troponin I Ser-150 and Ser-23/24 phosphorylation sustains thin filament Ca(2+) sensitivity playing an adaptive role to preserve contraction during acidic ischemia.

  7. these results indicate that the inability to enhance myofilament relaxation through cTnI phosphorylation predisposes the heart to abnormal diastolic function, reduced accessibility of cardiac reserves, dysautonomia, and hypertrophy.

  8. Dominant negative TnI-TnT interface mutation decreases the binding affinity of cTnI for TnT, causes early ventricular remodeling, and blunts the beta-adrenergic response of cardiac myocytes.

  9. R193H and R205H mutation increase the binding affinity of Troponin I for Troponin T and Troponin C.

  10. Conclude that dilated cardiomyopathy-causing mutations in thin filament proteins abolish the relationship between myofilament Ca(2+) sensitivity and troponin I phosphorylation by PKA.

Troponin I Type 3 (Cardiac) (TNNI3) Antigen Profile

Antigen Summary

Troponin I (TnI), along with troponin T (TnT) and troponin C (TnC), is one of 3 subunits that form the troponin complex of the thin filaments of striated muscle. TnI is the inhibitory subunit\; blocking actin-myosin interactions and thereby mediating striated muscle relaxation. The TnI subfamily contains three genes: TnI-skeletal-fast-twitch, TnI-skeletal-slow-twitch, and TnI-cardiac. This gene encodes the TnI-cardiac protein and is exclusively expressed in cardiac muscle tissues. Mutations in this gene cause familial hypertrophic cardiomyopathy type 7 (CMH7) and familial restrictive cardiomyopathy (RCM).
