            <strong>[[CDK1]]</strong>（<strong>[[Cyclin-Dependent Kinase 1]]</strong>，原名<strong>[[CDC2]]</strong>）是细胞周期调控系统的核心引擎，也是唯一一个被证实对所有真核细胞周期进程都不可或缺的[[CDK]]成员。[[CDK1]]属于[[丝氨酸/苏氨酸激酶]]家族，主要通过与<strong>[[Cyclin B]]</strong>结合形成复合物（即<strong>[[有丝分裂促进因子]]</strong>，[[MPF]]），驱动细胞从<strong>[[G2期]]向[[M期]]</strong>（[[有丝分裂]]）转换。作为细胞增殖的终极开关，[[CDK1]]在几乎所有恶性肿瘤中均呈现表达上调或活性失控。临床上，[[CDK1]]不仅是评估肿瘤增殖指数的关键指标，也是开发广谱[[CDK抑制剂]]及探索[[合成致死]]疗法的重要表观与细胞周期靶点。
