Anti-Umpk antibodies enable researchers to detect and measure the Umpk antigen in biological samples. This target is a reported synonym of the UCK2 gene, which encodes uridine-cytidine kinase 2. This protein is known to function in protein phosphorylation, among other biological roles. The human version of Umpk has a canonical amino acid length of 261 residues and a protein mass of 29.3 kilodaltons, although 2 isoforms have been identified. Umpk is a member of the Uridine kinase protein family.
