Creatine kinase MT 1A Proteins and Enzymes

Mitochondrial creatine (MtCK) kinase is responsible for the transfer of high energy phosphate from mitochondria to thecytosolic carrier, creatine. It belongs to the creatine kinase isoenzyme family. It exists as two isoenzymes,sarcomeric MtCK and ubiquitous MtCK, encoded by separate genes. Mitochondrial creatine kinase occurs in two differentoligomeric forms: dimers and octamers, in contrast to the exclusively dimeric cytosolic creatine kinase isoenzymes.Many malignant cancers with poor ...
