We have quantitated the interactions of two rabbit skeletal troponin C fragments with troponin I and the troponin I inhibitory peptide. The calcium binding properties of the fragments and the ability of the fragments to exert control in the regulated actomyosin ATPase assay have also been studied. The N- and C-terminal divalent metal binding domains of

Cardiac troponins are the preferred biomarkers in diagnostic of myocardial infarction, but these markers also can rise in response to exercise. Multiple studies have assessed troponins post-exercise, but the results have varied and there have been disagreements about the mechanism of troponin release. The aim of this paper was to review the literature,

Abstract Troponin was isolated from preparations of the ethylene glycol bis-(β-aminoethyl ether)-N,N′-tetraacetic acid (EGTA)-sensitizing factor over the pH range of 3.5–4.6. The variations among troponins were due essentially to differences in the proportion and properties of the troponin A component.

The troponin complex was discovered over thirty years ago and since then much insight has been gained into how this complex senses fluctuating levels of Ca(2+) and transmits this signal to the myofilament. Advances in genetics methods have allowed identification of mutations that lead to the phenotypically distinct cardiomyopathies: hypertrophic ...

Kardiales Troponin T (Cardial Troponin T)
Zeitschrift f�r Kardiologie, 1997Seit 1951 sind Messungen von kardialen Enzymen fester Bestandteil der Diagnostik von Patienten mit Infarktverdacht und dienen zusammen mit dem EKG der Klassifikation von Patienten mit Thoraxschmerz. Trotz erheblicher Fortschritte in der analytischen Methodik sind der Prazision der Infarktdiagnostik durch Enzyme enge Grenzen gesetzt, die sich aus der ...

Understanding cardiac troponin part 1: avoiding troponinitis [PDF]
Emergency Medicine Journal, 2017 Cardiac troponin (cTn) is a highly specific biomarker of myocardial injury and is central to the diagnosis of acute myocardial infarction (AMI). By itself, however, cTn cannot identify the cause of myocardial injury. ‘Troponinitis’ is the condition that leads clinicians to falsely assign a diagnosis of AMI based only on the fact that a patient has an ...

Serum Troponin is a sensitive and specific marker of heart muscle damage that is widely used in the assessment of people with chest pain. Its usefulness is, however, sometimes limited by false positive or negative results caused by proteins or fibrin in the patient's blood. More importantly, there is no agreed Troponin I standard at present which means

We have studied the interaction between troponin and tropomyosin by means of a fluorescent probe, N-(1- anilinonaphth -4-yl)maleimide (ANM), attached to the cysteine-190 residues of tropomyosin. The binding of troponin and troponin T to ANM-tropomyosin produces substantial increases in the label fluorescence.
