General annotation (Comments)

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 structure	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.
Sequence similarities	Belongs to the ATP:guanido phosphotransferase family.
