We demonstrated that checkpoint kinase-2 (chk2) binds to the beta-domain of pvhl and phosphorylates ser 111 on dna damage. Notably, this modification enhances pvhl-mediated transactivation of p53 by recruiting p300 and tip60 to the chromatin of p53 target gene |

The order and fidelity of cell cycle events in mammals is intimately linked to the integrity of the Chk1 kinase-Cdc25A phosphatase pathway. Chk1 phosphorylation targets Cdc25A for destruction and, as shown here, inhibits interactions between Cdc25A and its mitotic substrate cyclin B1-Cdk1. Phosphorylation of Cdc25A on serine 178 and threonine 507 facilitates 14-3-3 binding, and Chk1 phosphorylates both residues in vitro. |

Plk3 phosphorylates Chk2 at two residues, serine 62 (S62) and serine 73 (S73) in vitro, and this phosphorylation facilitates subsequent phosphorylation of Chk2 on T68 by ATM in response to DNA damage. When the Chk2 mutant construct GFP-Chk2 S73A (serine 73 mutated to alanine) is transfected into cells, it no longer associates with a large complex in vivo, and manifests a significant reduction in kinase activity. |

During interphase, cdc25 is inhibited by ser287 phosphorylation (xenopus cdc25;ser 216 in human cdc25c) and this inhibitory phosphorylation is maintained by dna-responsive checkpoints / s287 is targeted by many kinases, including chk1, chk2, ctak-1, pka, p38 and mapkap kinase-2 suggesting that phosphorylation of this site may integrate multiple signaling inputs. |

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. |

Chk2 is also autophosphorylated following dna damage. It is proposed that autophosphorylation of chk2 may contribute to chk2 activation. To fully understand the regulation of chk2, we mapped an in vitro chk2 autophosphorylation site at c-terminal serine 516 site (ser-516). Ser-516 of chk2 is phosphorylated following radiation in vivo, and this phosphorylation depends on the kinase activity of chk2. |

Thus, activation of chk2 in irradiated cells may occur through oligomerization of chk2 via binding of the thr-68-phosphorylated region of one chk2 to the fha domain of another. Oligomerization of chk2 may therefore increase the efficiency of trans-autophosphorylation resulting in the release of active chk2 monomers that proceed to enforce checkpoint control in irradiated cells. |

Tau pseudophosphorylation at specific sites such as s262, s293, s324 and s356 was reported to induce tau conformational change and attenuate tau binding to microtubules (fischer et al., 2009). Then, newly soluble tau proteins are targeted by post-translational modifications that directly or indirectly alter tau conformation, promoting tau dimerization in an anti-parallel manner. Stable tau dimers form tau oligomers, which continue in the aggregation process |

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. |

Found that chk2 associated with the b' regulatory subunit of protein phosphatase pp2a. In vitro kinase assays showed that b'gamma3 was a potent chk2 substrate. This phosphorylation increased the catalytic phosphatase activity of pp2a. |

Cell cycle progression is monitored constantly to ensure faithful passage of genetic codes and genome stability. We have demonstrated previously that, upon DNA damage, TTK/hMps1 activates the checkpoint kinase CHK2 by phosphorylating CHK2 at Thr68 |

The human protein N(α)-terminal acetyltransferase A complex (hNatA), composed of the catalytic hNaa10p (hArd1) and auxiliary hNaa15p (hNat1/NATH/Tubedown) subunits, was reported to be important for cell survival and growth of various types of cancer. lack of acetylation by hNatA activated H2A.X and Chk2 in both HCT116 cell lines independent of TP53 status (Fig. 6). |
