肌酸激酶，M 型（CKM）基因

该基因编码的蛋白质是一种参与能量稳态的细胞质酶，是心肌梗死的重要血清标志物。编码的蛋白质可逆地催化磷酸盐在 ATP 和各种磷原 (如磷酸肌酸) 之间的转移。它在横纹肌和其他组织中充当同二聚体，在心脏中充当具有相似脑同工酶的异二聚体。编码的蛋白质是 ATP:胍基磷酸转移酶蛋白质家族的成员。[RefSeq 提供，2008 年 7 月]

The protein encoded by this gene is a cytoplasmic Enzyme involved in energy homeostasis and is an important serum marker for myocardial infarction. The encoded protein reversibly catalyzes the transfer of phosphate between ATP and various phosphogens such as creatine phosphate. It acts as a homodimer in striated muscle as well as in other tissues, and as a heterodimer with a similar brain isozyme in heart. The encoded protein is a member of the ATP:guanido phosphotransferase protein family. [provided by RefSeq, Jul 2008]
