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.

Contains 1 phosphagen kinase C-terminal domain.

Contains 1 phosphagen kinase N-terminal domain.
