Western blot analysis of DGUOK over-expressed 293 cell line, cotransfected with DGUOK Validated Chimera RNAi ( Cat # H00001716-R01V ) (Lane 2) or non-transfected control (Lane 1). Blot probed with DGUOK monoclonal antibody (M02), clone 3E9 (Cat # H00001716-M02 ). GAPDH ( 36.1 kDa ) used as specificity and loading control.
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. [provided by RefSeq
