  1. Studies indicate that in patients with end-stage renal disease (ESRD), elevation of cardiac-specific troponin T (cTnT) was more frequent than elevation of troponin I (cTnI) [Review].

  2. the frequency of h-FABP (show FABP3 Proteins) positivity among acute myocardial infarction patients was higher than that of hs-TnI (show TNNI2 Proteins), which would have missed six of them; however, hs-TnI (show TNNI2 Proteins) area under curve was superior to that of h-FABP (show FABP3 Proteins).

  3. Reversible Covalent Reaction of Levosimendan with Cardiac Troponin C (show TNNC1 Proteins) in Vitro and in Situ.

  4. Mutations in genes encoding cardiac troponin I (TNNI3) and cardiac troponin T (TNNT2 (show TNNT2 Proteins)) caused altered troponin protein stoichiometry in patients with dilated cardiomyopathy. TNNI3p.98trunc resulted in haploinsufficiency, increased Ca(2 (show CA2 Proteins)+) -sensitivity and reduced length-dependent activation. TNNT2p.K217del caused increased passive tension.

  5. The QT interval has a strong positive linear correlation with cardiac troponin-I levels in Non-ST-elevation myocardial infarction.

  6. Apelin (show APLN Proteins)-12 influences troponin I levels in the acute phase of STEMI, whereas during the non-acute phase, low apelin (show APLN Proteins) levels were associated with a high rate of MACE.

  7. In clinical stable patients without known cardiovascular disease, a thorough chest-pain history in combination with hs-TnI (show TNNI2 Proteins) testing can identify a significant low-risk group.

  8. Study showed that in patients who underwent liver transplantation elevation of preoperative high-sensitivity cardiac troponin I level was associated with 1-year mortality and 30-day mortality.

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

  10. Plasma troponin C1 (cTnI) is biomarker of choice for diagnosing acute myocardial infarction (AMI (show CFD Proteins)) 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 (show CFD Proteins). These studies were conducted in emergency department of a university hospital in Italy using point-of-care testing in patients presenting with chest pain, ages 18-101.

Mouse (Murine) Troponin I Type 3 (Cardiac) (TNNI3) interaction partners

  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.

  3. The contributions of cardiac myosin binding protein C and troponin I phosphorylation to beta-adrenergic enhancement of in vivo cardiac function

  4. The difference in myosin regulatory light chain phosphorylation between the ventricles of R21C(+/+) in cardiac troponin I mice likely contributes to observed differences in contractile force and the lower tension monitored in the LV of HCM mice

  5. troponin I phosphorylation specifically alters the Ca(2 (show CA2 Proteins)+) sensitivity of isometric tension and the time course of relaxation in cardiac muscle myofibrils

  6. Combined troponin I Ser (show SIGLEC1 Proteins)-150 and Ser (show SIGLEC1 Proteins)-23/24 phosphorylation sustains thin filament Ca(2 (show CA2 Proteins)+) 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.

  1. By replacing rat cardiac troponin I (cTnI) in a mammalian cTn complex with trout cTnI it was demonstrated that this protein increases the Ca2+ affinity and reduces the influence of PKA phosphorylation on the Ca2+ affinity of the cTn complex.

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

Protein 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).
