Protein

Creatine kinase S-type, mitochondrial

Gene
CKMT2
Organism
Oryctolagus cuniculus (Rabbit)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at transcript leveli

Functioni

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 activityi

ATP + creatine = ADP + phosphocreatine.
