WebMar 31, 2015 · Troponin is a complex of three proteins: troponin C (TnC), troponin I (TnI) and troponin T (TnT). It plays a crucial role in the regulation of skeletal and cardiac muscle contraction . Troponin binds at regular intervals along the actin polymer on the thin filament. TnT is responsible for binding the whole complex to a tropomyosin molecule. WebTroponin is a protein complex expressed in cardiac and skeletal muscle. The complex consists of troponin I (TnI), troponin C (TnC) and troponin T (TnT), which enable the interaction between actin and myosin and are therefore fundamental to muscle contraction.There are cardiac-specific isoforms of troponin and these are abbreviated … WebApr 1, 2024 · Cardiac troponins I and T can be detected in the blood of most people after puberty, at concentrations reflecting cardiac mass, sex and age.
