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 By similarity.

Catalytic activity

ATP + creatine = ADP + phosphocreatine.

Subunit structure

Exists as an octamer composed of four MTCK homodimers By similarity.

Subcellular location

Mitochondrion inner membrane; Peripheral membrane protein; Intermembrane side By similarity.

Miscellaneous

Mitochondrial creatine kinase binds cardiolipin By similarity.

Sequence similarities

Belongs to the ATP:guanido phosphotransferase family.
