靶点详情

  • 功能：
    Phosphorylates the deoxyribonucleosides deoxycytidine, deoxyguanosine and deoxyadenosine. Has broad substrate specificity, and does not display selectivity based on the chirality of the substrate. It is also an essential enzyme for the phosphorylation of numerous nucleoside analogs widely employed as antiviral and chemotherapeutic agents.

    5. recently described a human deoxycytidine kinase mutant (G12) that sensitizes cancer cell lines to treatment with gemcitabine. Here, starting from the G12 variant, we identified a mutant that triggers even greater sensitisation to gemcitabine than G12. PMID: 26485161
