Creatine kinase (CK) is produced primarily in muscle, brain, and heart tissues, where it plays a crucial role in energy metabolism. It catalyzes the conversion of creatine and ATP (adenosine triphosphate) into phosphocreatine and ADP (adenosine diphosphate), facilitating the rapid regeneration of ATP during high-energy demands. The enzyme is synthesized from specific genes, with different isoforms (such as CK-MM in muscle and CK-MB in heart) produced depending on the tissue type. CK levels can be measured in the blood, and elevated levels often indicate muscle damage or stress.
