Additional slow migrating bands were observed in Ku70/80 (25, 50 and 100 nM) in the presence of RECQ1 (12.5 nM) (lanes 4–6 and 7–9). Fig. 5 Effect of Ku70/80 and DNA-PKcs on Trx-RAG-mediated cleavage of linear DNA. A, linear DNA substrates were incubated with Trx-RAGs, in the absence or presence of HMGB1 (50 (top gel) or 500 ng (bottom gel)), Ku70/80, and DNA-PKcs. Bottom, percentage of SE product is shown. Substrate and cleavage products are represented to the left.

(2006) showed that Ku heterodimers on DNA ends were in dynamic equilibrium with Ku70/Ku80 in solution, suggesting  dependent upon Ku70/80, XRCC4 and DNA ligase IV. In mammals, this process also requires DNA-PKcs, the catalytic subunit of the DNA-dependent protein  3 Mar 2020 Measuring the binding affinity of Ku70/80 to dsDNA using microfluidic diffusional sizing.

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.

These molecules are visualized, downloaded, and analyzed by users who range from students to specialized scientists. 2008-11-1 · KU70/80, DNA-PKcs, and Artemis are essential for the rapid induction of apoptosis after massive DSB formation.

The yeast homologue of Ku70/80, yKu70/80, fails to bind IP 6, indicating that the function of IP 6 in non‐homologous end‐joining, like that of DNA‐PK cs, is unique to the mammalian end‐joining process.

2020-10-19 · DNA double-strand breaks are the most dangerous type of DNA damage and, if not repaired correctly, can lead to cancer. In humans, Ku70/80 recognizes DNA broken ends and recruits the DNA-dependent

It was reported that activation of ATM- and Rad3-related (ATR) kinase by DSBs also occurs in an ATM-dependent manner. On the other hand, Ku70/80 is The dynamics of Ku70/80 and DNA-PKcs at DSBs induced by ionizing radiation is dependent on the complexity of damage. Reynolds P(1), Anderson JA, Harper JV, Hill MA, Botchway SW, Parker AW, O'Neill P. Author information: (1)Department of Oncology, Gray Institute for Radiation Oncology & Biology, University of Oxford, Oxford OX3 7DQ, UK. The Ku70/80 complex recognizes DNA breaks and serves as an essential hub for recruitment of NHEJ components. Here, we describe intramolecular interactions of the Ku70 C-terminal domain, known as the SAP domain. Using single-particle cryo-electron microscopy, mass spectrometric analysis of intermolecular crosslinking and molecular modelling The heterodimer, Ku70/80, is an early player in DSB repair and is part of the non-homologous end joining (NHEJ) repair pathway. Ku70/80 binds to both ends of the dsDNA at the damaged sites, acting as a marker to recruit other repair proteins required for NHEJ.

First, using various WRN deletion mutants we show that 50 amino acids at the amino terminus are required and sufficient to interact with Ku70/80. Ku70/80 also interacts with the telomeric factor Trf1 and plays an important role in telomere maintenance (Bailey et al., 1999; Hsu et al., 1999, 2000; Gasser, 2000).

Besides sensing, Ku70/80 complex possibly tethers broken DNA ends keeping them in close vicinity for end-processing and subsequent ligation. Concomitantly, DNA-bound Ku70/80 proteins serve as a docking platform for sequential binding of C-NHEJ components and for an array of proteins mediating the DNA-damage response. 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 2016-07-01 · Human Ku70/80 was added to a final concentration of 20 ng/μl.

Both RECQ1 and Ku70/80 bind to blunt duplex resulting in a series of progressively retarded bands, but the mobility of RECQ1-DNA and Ku70/80-DNA complex is distinct. Additional slow migrating bands were observed in Ku70/80 (25, 50 and 100 nM) in the presence of RECQ1 (12.5 nM) (lanes 4–6 and 7–9).
