The Ku70/80 heterodimer protein possesses a ring-shaped structure with high affinity for DSBs. Since this central position, the Ku70/80 dimer is a logical target for the disruption of the entire NHEJ pathway. Surprisingly, specific inhibitors of the Ku70/80 heterodimer are currently not available.

DNA PK consists of a heterodimeric DNA-binding subunit (Ku70/80) and an approximately 465 kDa catalytic subunit (DNA PKcs). Den Ku70/Ku80 heterodimer binder till DSB slutar, rekrytera DNA-PKcs och p53 Bindande Odla celler till 80% konfluency (cirka 24 timmar).

2005-4-11 · Ku70/80 associates with telomeric DNA and binds to TRF1 and TRF2 (14,15). Moreover, Ku has been reported to associate with hTERT and telomerase activity . However, the precise biological consequence, the biochemical nature of these interactions and the role of DNA-PK in telomere maintenance remain unknown.

2008-11-01 · In addition, KU70/80 has variety of DNA-PKcs-dependent or -independent functions such as initiation of DNA replication , and telomere maintenance . However here we bring up that KU70/80 has another role in transmitting apoptosis signal as DNA-PK complex contrary to anti-apoptotic protein.

Ku70/80 associates with telomeric DNA ( 13) and binds to TRF1 and TRF2 ( 14, 15). Moreover, Ku has been reported to associate with hTERT and telomerase activity ( 16). However, the precise biological consequence, the biochemical nature of these interactions and the role of DNA-PK in telomere maintenance remain unknown.

Validated in WB, IHC and tested in Human. Cited in 4 publication(s). Immunogen corresponding to synthetic peptide. 2013-05-01 · When both Ku70/80 and RECQ1 were incubated with fork duplex in the presence of ATPγS, we observed a super-shifted species that is distinct from those obtained with binding of the fork DNA with Ku70/80 or RECQ1 alone (Fig. 3A, lane 3), indicating that Ku70/80 and RECQ1 can together bind the fork DNA structure. Persson, Oscar et al.

Results Ku70/80 and DNA‐PKcs were loaded onto biotinylated DNA that was immobilized on streptavidin beads and then incubated with either full‐length WRN or a mutant WRN missing the C‐terminal region [WRN(1–748)]. The reaction mixture was incubated for 30 min at 4°C and the unbound material was removed by extensive washes. We found that Ku70/80, but not DNA-PK CS, is required for XRCC4 accumulation at DSBs, which is explained by our observation of a direct interaction between the XRCC4 and Ku70 polypeptides. Taken together these results support the view that the core of all NHEJ complexes revolves around the Ku–XRCC4 interaction.

Ku70/80 concentration and DNA-binding rate as well as XXL concentration and enzymatic activity are introduced as the best targets for affecting NHEJ DSB repair process. On the basis of the current The Ku heterodimer Ku70/80 is required for the NHEJ (non-homologous end-joining) DNA DSB repair pathway. The INHAT (inhibitor of histone acetyltransferases) complex subunit, SET/TAF-Iβ, can inhibit p300- and PCAF-mediated acetylation of both histone and p53, thereby repressing general transcription and that of p53 target genes. 2005-4-11 · Ku70/80 associates with telomeric DNA and binds to TRF1 and TRF2 (14,15).

In particular, the invention relates to  Inhibition of the Ku DNA end-binding activity by transfection with the C-terminal Ku80 expression gene suppressed cell proliferation. Ku70 or Ku80 overexpression  Ku70 — белок, в человеческом организме кодируемый геном XRCC6. Содержание.

paradoxical that Ku70/80, a protein that facilitates the joining of DNA ends, is localized at telomeres. Further analysis however suggested that a likely explanation for these observations is that Ku70/80 plays distinct roles at pathological and natural DNA ends. Indeed, Ku70/80 has been proposed to perform at least two functions at telomeres.

Eukaryotic Ku is a heterodimer of two polypeptides, Ku70 (XRCC6) and Ku80 (XRCC5), so named because the molecular weight of the human Ku proteins is around 70 kDa and 80 kDa. The two Ku subunits form a basket-shaped structure that threads onto the DNA end.
