Deoxycytidine kinase (dCK) is a nucleoside kinase which is involved in the deoxynucleoside salvage-pathway and thus responsible for the conversion of deoxycytidine (dC), deoxyadenosine (dA) and deoxyguanosine (dG) into their monophosphate forms. By this means cells are supplied with deoxyribonucleotides for DNA replication and repair synthesis. In addition to its natural substrates dCK is also able to activate numerous nucleoside analogues used in cancer and antiviral chemotherapy. The enzyme is higly expressed in lymphoid tissues and beside there is an increase dCK activity in solid tumours.

dCK is recombinantly expressed in E. coli, fused to GST and purified using affinity chromatography MW. 56 kDa
