CC -!- FUNCTION: Reversibly catalyzes the transfer of phosphate between ATP
CC and various phosphogens (e.g. creatine phosphate). Creatine kinase
CC isoenzymes play a central role in energy transduction in tissues with
CC large, fluctuating energy demands, such as skeletal muscle, heart,
CC brain and spermatozoa. {ECO:0000256|ARBA:ARBA00037274}.
CC -!- SUBUNIT: Exists as an octamer composed of four MTCK homodimers.
CC {ECO:0000256|ARBA:ARBA00038753}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane
CC {ECO:0000256|ARBA:ARBA00004137}; Peripheral membrane protein
CC {ECO:0000256|ARBA:ARBA00004137}; Intermembrane side
CC {ECO:0000256|ARBA:ARBA00004137}.
CC -!- SIMILARITY: Belongs to the ATP:guanido phosphotransferase family.
CC {ECO:0000256|ARBA:ARBA00006798, ECO:0000256|PROSITE-ProRule:PRU00842,
CC ECO:0000256|RuleBase:RU000505}.
