- FUNCTION: Reversibly catalyzes the transfer of phosphate between ATP and various phosphogens (e.g. creatine phosphate). Creatine kinase isoenzymes play a central role in energy transduction in tissues with large, fluctuating energy demands, such as skeletal muscle, heart, brain and spermatozoa.
- CATALYTIC ACTIVITY: ATP + creatine = ADP + phosphocreatine.
- SUBUNIT: Dimer of identical or non-identical chains. With MM being the major form in skeletal muscle and myocardium, MB existing in myocardium, and BB existing in many tissues, especially brain.
- SUBCELLULAR LOCATION: Cytoplasm.
- MISCELLANEOUS: This electric ray muscle-specific creatine kinase (MM isozyme) is isolated from the electric organ, which derives embryologically from skeletal muscle. It may be involved in the electrical discharge process.
- SIMILARITY: Belongs to the ATP:guanido phosphotransferase family.
