UMP-CMP kinase is an enzyme that in humans is encoded by the CMPK1 gene.[1][2]


Uridine monophosphate (UMP)/cytidine monophosphate (CMP) kinase (EC catalyzes the phosphoryl transfer from ATP to UMP, CMP, and deoxy-CMP (dCMP), resulting in the formation of ADP and the corresponding nucleoside diphosphate. These nucleoside diphosphates are required for cellular nucleic acid synthesis.[2][3]
