General description
Research area: Cell Signaling
Creatine Kinase (CK) comprises M and B subunit and is a dimeric molecule. It is one among the isoenzymes of CK. The enzyme is majorly present in the myocardium.

Application
Creatine Kinase MB Fraction from human heart has been used:
- as a diagnostic marker for acute myocardial infarction.
- to identify overlapping absorbance peaks between blood and the cardiac biomarkers.
- to study the phosphorylation pathway of dioxolane guanosine (DXG) in vivo, a potential treatment of HIV-1 infection.
Biochem/physiol Actions
Creatine Kinase (CK) catalyzes the formation of creatinine from creatine phosphate. The enzyme is associated with coronary performance. Elevated serum levels of CK-MB are prime indicators of myocardial cellular injury. It is regarded as a “gold standard” for myocardial infarction diagnosis. The levels of cardiac troponin I (cTnI) or cardiac troponin T also correlate to higher CK-MB) levels. CK-MB levels may also be elevated in chronic renal failure.
