RN [1]
RP NUCLEOTIDE SEQUENCE [LARGE SCALE MRNA].
RC TISSUE=Kidney;
RG The German cDNA consortium;
RL Submitted (NOV-2004) to the EMBL/GenBank/DDBJ databases.
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 (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + creatine = ADP + H(+) + N-phosphocreatine;
CC Xref=Rhea:RHEA:17157, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:57947, ChEBI:CHEBI:58092, ChEBI:CHEBI:456216; EC=2.7.3.2;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU10029};
CC -!- SUBUNIT: Exists as an octamer composed of four CKMT2 homodimers.
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000250};
CC Peripheral membrane protein {ECO:0000250}; Intermembrane side
CC {ECO:0000250}.
CC -!- MISCELLANEOUS: Mitochondrial creatine kinase binds cardiolipin.
CC -!- SIMILARITY: Belongs to the ATP:guanido phosphotransferase family.
CC {ECO:0000255|PROSITE-ProRule:PRU00842, ECO:0000255|PROSITE-
CC ProRule:PRU00843}.
