DCK（deoxycytidine kinase），癌症关联基因，基因ID：1633，脱氧胞苷激酶（dck）是几种脱氧核苷及其类似物磷酸化所必需的。DCK缺乏与对抗病毒和抗癌化疗药物的耐药性有关相反，激酶活性增加与这些化合物对细胞毒性核苷三磷酸衍生物的活化增加有关。dck与耐药性和敏感性有关，具有重要的临床意义。[由RefSeq提供，2008年7月] Deoxycytidine kinase (DCK) is required for the phosphorylation of several deoxyribonucleosides and their nucleoside analogs. Deficiency of DCK is associated with resistance to antiviral and anticancer chemotherapeutic agents. Conversely， increased deoxycytidine kinase activity is associated with increased activation of these compounds to cytotoxic nucleoside triphosphate derivatives. DCK is clinically important because of its relationship to drug resistance and sensitivity. [provided by RefSeq， Jul 2008]。
