deoxyguanosine kinase  M-CSA #615

Deoxyribonucleoside kinases such as deoxyguanoside kinase (dGK) phosphorylate deoxyribonucleosides. The human form is highly specific for purine substrates. Deoxynucleoside kinases are key targets in chemotherapy of cancer as they are recquired to activate nucleoside analogues by phosphorylation. dGK is involved in the regulation of dGTP and dATP pools, and may have a role in apoptosis.
