| 背景 | cdc25 is a protein phosphatase responsible for dephosphorylating and activating cdc2, a crucial step in regulating the entry of all eukaryotic cells into mitosis (1). cdc25C is constitutively phosphorylated at Ser216 throughout interphase by c-TAK1, while phosphorylation at this site is DNA damage-dependent at the G2/M checkpoint (2). When phosphorylated at Ser216, cdc25C binds to members of the 14-3-3 family of proteins, sequestering cdc25C in the cytoplasm preventing premature mitosis (3). The checkpoint kinases Chk1 and Chk2 phosphorylate cdc25C at Ser216 in response to DNA damage (4,5).cdc25蛋白磷酸酶负责cdc2的去磷酸化和激活，该过程是真核细胞进入有丝分裂的关键调节步骤(1)。整个分裂间期cdc25C丝氨酸216位发生c-TAK1引起的组成性磷酸化，而该位点的磷酸化在G2/M期检验点是不依赖DNA损伤的(2)。当216位丝氨酸磷酸化时，cdc25C结合14-3-3蛋白家族的成员，扣押胞质cdc25C从而阻止有丝分裂的过早发生(3)。检验点蛋白激酶Chk1和Chk2磷酸化cdc25C216位丝氨酸以响应DNA损伤(4,5)。 |
