Engelsk definition
A TROPONIN complex subunit that binds to TROPOMYOSIN. There are three troponin T subtypes: troponin T1, T2 and T3. Troponin T2 is cardiac-specific whereas troponin T2 and T3 are skeletal subtypes. Troponin T2 is a BIOMARKER for damaged or injured CARDIAC MYOCYTES and mutations in troponin T2 gene are associated with FAMILIAL HYPERTROPHIC CARDIOMYOPATHY.
