Recombinant human UMP-CMP kinase (UMP-CMPK), also known as CMPK1 or cytidine/uridine monophosphate kinase, is a key enzyme in nucleotide metabolism. Belonging to the nucleoside monophosphate kinase family, it catalyzes the phosphorylation of UMP (uridine monophosphate) and CMP (cytidine monophosphate) to UDP (uridine diphosphate) and CDP (cytidine diphosphate), utilizing ATP as a phosphate donor. This reaction is critical for maintaining balanced nucleotide pools required for RNA/DNA synthesis and cellular energy transfer. The enzyme localizes primarily in the cytoplasm and mitochondria, with mitochondrial isoforms implicated in mitochondrial DNA synthesis and homeostasis. Dysregulation of UMP-CMPK activity is associated with metabolic disorders, viral replication mechanisms, and cancer progression. Recombinant production of human UMP-CMPK, typically via bacterial or mammalian expression systems, enables detailed structural and functional studies. Its high purity and activity make it valuable for biochemical assays, drug discovery (e.g., antiviral or anticancer agents targeting nucleotide metabolism), and elucidating metabolic adaptations in pathological states. Recent studies also explore its role in immune responses and mitochondrial dysfunction-linked diseases, highlighting broad therapeutic relevance.
