troponin
Muscle contraction regulator
Troponin is a protein complex in muscle tissue that regulates contraction.
In medicine, cardiac troponin levels in the blood serve as a key marker for heart damage—elevated troponin indicates heart muscle injury, making it the primary test for diagnosing heart attacks: Her troponin levels were dangerously high.
