It is involved in the regulation of the contraction of a cross-striated muscle.
Troponin is a major component of muscle tissue. It is composed of troponin C, troponin I, and troponin T. Troponin interacts with tropomyosin and myosin to create muscle contraction.
troponin molecules.
The theraputic troponin level is 0.00.
Troponin testing is done to diagnose heart attacks (myocardial infarctions).
Calcium is released from the sarcoplasm to bind with the troponin which allows the tropomyosin the reveal the binding sites on the actin so the muscle can contract
cardiac troponin I tests measure only cardiac troponin; tests for cardiac troponin T may cross-react with troponin found in other muscles and give positive or increased results in the absence of heart damage.
Troponin is a cardiac enzyme that your heart releases under stress.
Actin and myosin
Both troponin T and I are cardiac markers used to diagnose myocardial infarctions.
Emily Jane Austin has written: 'Characterisation of the interaction sites between Troponin T and Troponin C of the Troponin complex from human cardiac muscle'
Cardiac troponin levels are usually too low to measure. Elevated troponin T levels indicate that there has been some form of damage to the heart.Strenuous exercise can also temporarily elevate troponin levels for a brief time. The effects of a heart attack would keep troponin T levels elevated for up to two weeks.
