Function

In mammalian cells, the phosphorylation of purine deoxyribonucleosides is mediated predominantly by two deoxyribonucleoside kinases, cytosolic deoxycytidine kinase and mitochondrial deoxyguanosine kinase. The protein encoded by this gene is responsible for phosphorylation of purine deoxyribonucleosides in the mitochondrial matrix. In addition, this protein phosphorylates several purine deoxyribonucleoside analogs used in the treatment of lymphoproliferative disorders, and this phosphorylation is critical for the effectiveness of the analogs. Alternative splice variants encoding different protein isoforms have been described for this gene.[5]

gollark: Firefox, but resentfully.
gollark: Either they don't implement enough of the web standards to be useful, or they're too gigantic and complex to have good code quality and work well.
gollark: Actually, no browsers are good and you cannot be spared.
gollark: Browsers *are* among the most horrifically bloated and complex software.
gollark: It's quite nice.
