Accumulation of XRCC4/ligase IV on DSBs depended on the presence of Ku70/80, but not DNA-PK CS. We detected a direct interaction between Ku70 and XRCC4 that could explain these requirements. Our results 2009-11-11 Werner's syndrome (WS) is an inherited disease characterized by genomic instability and premature aging. The WS gene encodes a protein (WRN) with helicase and exonuclease activities. We have previously reported that WRN interacts with Ku70/80 and this interaction strongly stimulates WRN exonuclease activity. To gain further insight on the function of WRN and its relationship with the Ku XRCC5 (X-Ray Repair Cross Complementing 5) is a Protein Coding gene.
Through protein fractionation and biochemical experiments, we find that Ku70/Ku80 and DNA-dependent protein kinase catalytic subunit (DNA-PKcs) modulate RAG-mediated cleavage. Modulation of cleavage by Ku70/80 The Ku70/80 heterodimer is the regulatory subunit of the DNA-dependent protein kinase (DNA-PK) and its DNA-binding activity mediates DNA double-strand breaks repair. Although Ku80 was recently 2016-7-1 · The Ku70/80 heterodimer protein plays a pivotal role in the NHEJ process. It possesses a ring-shaped structure with high affinity for DSBs and serves as the first responder and central scaffold around which the rest of the repair complex is assembled.
The Ku70/80 heterodimer is a major player in non-homologous end joining and the repair of DNA double-strand breaks. Studies suggest that once bound to a DNA double-strand break, Ku recruits the catalytic subunit of the DNA-dependent protein kinase (DNA-PKcs) to form the DNA-dependent protein kinase …
Compound L was added as solution in DMSO (final concentration DMSO in the EMSA reaction mixture was 5%). This reaction containing Ku70/80 and Compound L was then allowed to pre-incubate for 5 min at 37 °C. The Ku70/80 heterodimer is a major player in non-homologous end joining and the repair of DNA double-strand breaks. Studies suggest that once bound to a DNA double-strand break, Ku recruits the catalytic subunit of the DNA-dependent protein kinase (DNA-PKcs) to form the DNA-dependent protein kinase … 2019-05-17 · The Ku70/80 heterodimer protein possesses a ring-shaped structure with high affinity for DSBs.

Bottom, percentage of SE product is shown. Substrate and cleavage products are represented to the left. 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. The Ku70/80 heterodimer is the regulatory subunit of the DNA-dependent protein kinase (DNA-PK) and its DNA-binding activity mediates DNA double-strand breaks repair.

Recombinant Human Ku70 & Ku80 Heterodimer Protein (Met1-Ile732 & Met1-Asp609) CT018-H07B with a fusion His Tag, is expressed in Baculovirus-Insect Cells. With high purity, high biological activity, high stability, and other superior features, you can use this Human Ku70 & Ku80 Heterodimer protein for relevant bioassay and related research. The relative intensity of the bands in Fig. 5 suggests that the interaction is specific for Ku70/80 heterodimers. Although the intensity of the Ku70 band in the input mixture was greater than that for Ku80, roughly equal amounts of both were co-precipitated by the anti-HA and anti-p23 antibodies.

Figure 1: Equilibrium binding curve of Ku70/80 and FAM-labeled dsDNA oligonucleotide (18 bp). Measurements were performed in triplicate. K D was determined by non-linear least squares fitting. 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.
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. The Ku70/80 complex recognizes DNA breaks and serves as an essential hub for recruitment of NHEJ components. Here, we describe intramolecular … Nonhomologous end joining (NHEJ) is a DNA repair mechanism that religates double-strand DNA breaks to maintain genomic integrity during the entire cell cycle.

The Ku70/80 crystal structure (Fig. 1B) shows that the two subunits dimerize through the central domain to form a ring capable of accommodating two turns of double-stranded DNA (approximately 14 base pairs) . This ring, consisting of intertwined strands of both Ku70 and Ku80, is lined with positively charged residues positioned to interact with

Here, we describe intramolecular … Nonhomologous end joining (NHEJ) is a DNA repair mechanism that religates double-strand DNA breaks to maintain genomic integrity during the entire cell cycle. Our previous studies indicated that the Werner syndrome protein (WRN) interacts with Ku, a heterodimeric factor of 70- and 80-kDa subunits implicated in the repair of double strand DNA breaks. Moreover, we demonstrated that Ku70/80 strongly stimulates and alters WRN exonuclease activity.
Simplified, Ku70/80 complex is a sensor of DSBs that initiates the assembly of C-NHEJ complex to restore integrity of a DNA molecule. In fact, the role of Ku70/80 proteins is highly complex and integrates different aspects of DNA repair.
