DNA-PK/Chk2 induces centrosome amplification during prolonged replication stress.
Taipei, Taiwan. In Oncogene, 24 Apr 2014
Here, we examined the involvement of ataxia telangiectasia, mutated (ATM), ataxia telangiectasia, mutated and Rad3-related (ATR) and DNA-dependent protein kinase (DNA-PK) and found that HU-induced centrosome amplification was inhibited by the depletion of DNA-PKcs, but not ATM and ATR.
Structural insights into NHEJ: Building up an integrated picture of the dynamic DSB repair super complex, one component and interaction at a time.
Berkeley, United States. In Dna Repair (amst), 19 Apr 2014
X-ray crystal structures, cryo-electron microscopy envelopes, and small angle X-ray scattering (SAXS) solution conformations and assemblies are defining most of the core protein components for NHEJ: Ku70/Ku80 heterodimer; the DNA dependent protein kinase catalytic subunit (DNA-PKcs); the structure-specific endonuclease Artemis along with polynucleotide kinase/phosphatase (PNKP), aprataxin and PNKP related protein (APLF); the scaffolding proteins XRCC4 and XLF (XRCC4-like factor); DNA polymerases, and DNA ligase IV (Lig IV).
Regulation of DNA repair by S-nitrosylation.
San Francisco, United States. In Biochim Biophys Acta, 2012
MAJOR CONCLUSIONS: Recent studies have identified a number of key DNA repair proteins as targets of S-nitrosylation, including O(6)-alkylguanine-DNA-alkyltransferase (AGT), 8-oxoguanine glycosylase, apurinic-apyrimidinic endonuclease 1, and DNA-dependent protein kinase catalytic subunit.
More forks on the road to replication stress recovery.
Fort Collins, United States. In J Mol Cell Biol, 2011
In recent years, several proteins involved in DSB repair by non-homologous end joining (NHEJ) have been implicated in the replication stress response, including DNA-PKcs, Ku, DNA Ligase IV-XRCC4, Artemis, XLF and Metnase.
Tel2 regulates the stability of PI3K-related protein kinases.
New York City, United States. In Cell, 2008
The effects of Tel2 deletion correlated with significantly reduced protein levels for the PI3K-related kinases ataxia telangiectasia mutated (ATM), ATM and Rad3 related (ATR), DNA-dependent protein kinase catalytic subunit ataxia (DNA-PKcs).
