Creatine kinase (CK, EC 2.7.3.2), also known as creatine phosphokinase, is an enzyme cata lyzing the phosphorylation of creatine. CK utilizes adenosine triphosphate (ATP) to rever sibly produce phosphocreatine (PCr) and adenosine diphosphate (ADP). Therefore, ATP c an be regenerated from PCr and ADP. CK is expressed by various tissues and cell types, mainly found in skeletal muscle, cardiac muscle, and the brain, bladder, stomach, and col on. The ubiquity of CK in many tissues causes a poor specificity. In tissues and cells that consume ATP rapidly, especially skeletal muscle, PCr functions as an energy reservoir for the rapid buffering and regeneration of ATP in situ, as well as for intracellular energy tra nsport by the PCr shuttle or circuit. CK is of great importance in skeletal muscle energy metabolism. CK concentration could be elevated by muscle necrosis or disease. Therefore , CK is clinically assayed as a marker of damage of CK-rich tissue and may also be measur ed to evaluate myopathy.
