[1]	NUCLEOTIDE SEQUENCE [MRNA]. PubMed=3857581 [NCBI, ExPASy, EBI, Israel, Japan] Pickering L., Pang H., Biemann K., Munro H., Schimmel P.; "Two tissue-specific isozymes of creatine kinase have closely matched amino acid sequences."; Proc. Natl. Acad. Sci. U.S.A. 82:2310-2314(1985).

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: 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.
SIMILARITY: Belongs to the ATP:guanido phosphotransferase family.
