CMPK Catalyzes the phosphorylation of pyrimidine nucleoside monophosphates at the expense of ATP. Plays an important role in de novo pyrimidine nucleotide biosynthesis. Has preference for UMP and CMP as phosphate acceptors. Also displays broad nucleoside diphosphate kinase activity. Belongs to the adenylate kinase family. UMP-CMP kinase subfamily. Ubiquitously expressed. 3 alternative splicing and alternative initiation human isoforms have been reported. Note: This description may include information from UniProtKB.
