Background
Pyrimidine nucleoside monophosphate kinase [UMP/CMP kinase (UMP/CMPK)] (CMPK1) is also named as CMK, CMPK, UCK, UMK, UMPK and belongs to the adenylate kinase family. The gene of encodes one of the enzymes required for cellular nucleic acid biosynthesis. CMPK1 plays an important role in de novo pyrimidine nucleotide biosynthesis. This enzyme catalyzes the transfer of a phosphate group from ATP to CMP, UMP, or dCMP, to form the corresponding diphosphate nucleotide. Alternate splicing results in both coding and non-coding transcript variants. CMPK1 has been reported as a prognostic marker for non-small cell lung cancer, pancreatic cancer and breast cancer. It has 3 isoforms with the molecular mass of 22, 16 and 26 kDa. The longest deduced protein contains 228 amino acids and has a calculated molecular mass of 26 kD.
