Chk1 activated by ataxia telangiectasia mutated (ATM) kinase on DNA breaks in G1 promotes NHEJ through direct phosphorylation of ASF1A at Ser-166. ASF1A phosphorylated at Ser-166 interacts with the repair protein MDC1 and thus enhances MDC1's interaction with ATM and the stable localization of ATM at DNA breaks. |

We show that chk1 s301 phosphorylation increases as cells progress through s and g2 and that both cdk1 and cdk2 are likely to contribute to this modification in vivo. We also find that substitution of s286 and s301 with non-phosphorylatable alanine residues strongly attenuates dna damage-induced chk1 activation and g2 checkpoint proficiency |

In this study, we report a novel phosphorylation site serine 331 (S331) of FANCD2, the pivotal downstream player of the Fanconi anemia pathway. Phosphorylation of S331 is important for its DNA damage-inducible monoubiquitylation, resistance to DNA cross-linkers, and in vivo interaction with FANCD1/BRCA2.|In vitro and in vivo experiments show that phosphorylation of S331 is mediated by CHK1, |

The chk1 and chk2 kinases have also been shown to phosphorylate ser367, leading to 14-3-3 binding (34_36, 38, 44). In both cases, the outcome differed: in chk1-mediated phosphorylation, mdmx was translocated to the cytoplasm;in chk2-mediated phosphorylation, mdmx was degraded (34_36, 38, 44). It is possible that the damage response is mediated through additional phosphorylation sites other than ser367 and that, depending on the type of damage, certain sites will be modified, leading to different outcomes. |

Here we show that phosphorylated Metnase feeds back to increase the half-life of Chk1. Chk1 half-life is regulated by DDB1 targeting it to Cul4A for ubiquitination and destruction. Metnase decreases Chk1 interaction with DDB1, and decreases Chk1 ubiquitination. |

We now provide evidence that BLM undergoes K48-linked ubiquitylation and subsequent degradation during mitosis due to the E3 ligase, Fbw7α. Fbw7α carries out its function after GSK3β- and CDK2/cyclin A2-dependent phosphorylation events on Thr171 and Ser175 of BLM which lies within a well-defined phosphodegron, a sequence which is conserved in all primates.Phosphorylation on BLM Thr171 and Ser175 depends on prior phosphorylation at Thr182 by Chk1/Chk2. Thr182 phosphorylation not only controls BLM ubiquitylation and degradation during mitosis but is also a determinant for its localization on the ultrafine bridges. |

Reciprocally, Chk1 engages a negative feedback loop to prevent hyperactivation of Ras-MEK signaling, thereby limiting DNA damage. Ras–MEK signaling transcriptionally activates Chk1, which appears to sustain cancer cell growth by maintaining DNA damage levels below a threshold that would otherwise drive apoptosis. |

Involvement of GSK3 Inhibition by the PI3K/Akt Pathway in Regulation of Etoposide-induced Chk1 Activation. GSK3ß regulates etoposide-induced Chk1 activation. GSK3 inhibitors, including LiCl and SB216763, restored the sustained Chk1 activation and mitigated apoptosis in cells treated with etoposide and the inhibitors for aberrant kinases, PI3K, or Akt. Thus, proteasomal degradation of Chk1 as well as GSK3 activation may be involved in negative regulation of etoposide-induced Chk1 by imatinib in these cells. |
