Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. These molecules are visualized, downloaded, and analyzed by users who range from students to specialized scientists.

2012-2-10 · Human Ku70/80 protein blocks exonuclease 1-mediated DNA resection in the presence of human Mre11 or Mre11/Rad50 protein complex. Sun J(1), Lee KJ, Davis AJ, Chen DJ. Author information: (1)Division of Molecular Radiation Biology, Department of Radiation Oncology, University of Texas Southwestern Medical Center at Dallas, Dallas, Texas 75390, USA. 2020-10-4 · The Ku70 was similarly decreased (by 2.1-, 1.5- and 1.7-fold, respectively) in Ku80+/- cells. sites within the imprinting control center of the H19 and Igf2 genes bind Ku70/80 in a sequence-specific manner and with higher affinity than previously reported binding sites The Ku70/80 heterodimer binds to DNA ends and attracts other proteins involved in the non-homologous end-joining (NHEJ) pathway of DNA double-strand break repair. We developed a novel assay to measure DNA binding and release kinetics using differences in Förster resonance energy transfer (FRET) of the ECFP-Ku70/EYFP-Ku80 heterodimer in soluble and DNA end bound states.

Moreover, we demonstrated that Ku70/80 strongly stimulates and alters WRN exonuclease activity. In this report, we investigate further the association between WRN and Ku70/80. 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). Conformational changes in Ku70/80 could affect this interaction and impinge upon whether Ku70/80 binds Trf1 and acts at telomeres, or alternatively participates in NHEJ.

Double strand break (DSB) recognition is the first step in the DSB damage response and involves activation of ataxia telangiectasia-mutated (ATM) and phosphorylation of targets such as p53 to trigger cell cycle arrest, DNA repair, or apoptosis. It was reported that activation of ATM- and Rad3-related (ATR) kinase by DSBs also occurs in an ATM-dependent manner.

o A dimer called KU (70 and 80, respec%vely) come along and protect the ends. o These bring along DNA-PK. CS . Hangs out as a dimer (looks like a handle),.

Indeed, Ku70/80 has been proposed to perform at least two functions at telomeres. The Ku70/80 heterodimer is shown in ribbon representation to better see the DNA as it is encircled by the toroidal Ku70/80 protein. The color scheme was the same as A . 2017-08-25 · KU70/80 in the DNA-PK complex adopts an overall fold similar to that in the KU70/80-DNA structure (PDB: 1JEY), with an RMSD of 2.44 Å for 838 aligned Cα (Supplementary information, Figure S6). Ku70/80 mediates a recognition of DNA breaks to initiate nonhomologous end joining, an important DNA repair mechanism for maintaining genomic integrity.

To assess HR frequency in KD‐Ku70/80 or KD‐Lig4 in detail, the establishment of an HR assay system in rice is also required to detect the reconstruction of the recombination substrate only via HR, for example, intrachromosomal HR reporter with indirect repeats (Gherbi et al., 2001) or interchromosomal HR reporter (Molinier et al., 2004).

Ku70 вместе с белком Ku80 составляют гетеродимерный Ku-бело 27 Apr 2010 The importance of the Ku70 and Ku80 proteins in DNA DSB repair after low-LET radiation is well demonstrated by the profound enhancement Ku70/80-CLU-Bax interactions. (A) Bax is localized inactive in the cytoplasm in normal, undamaged cell interacting with the Ku70 protein C-terminus. sCLU Monoclonal Antibody for studying Ku70 in the Cell Cycle / Checkpoint research Ku is a heterodimeric protein composed of two subunits (Ku70 and Ku80) Ku70 & Ku80 Heterodimer Proteins Research Reagents. Ku is a heterodimer of two proteins termed Ku70 (69kDa, encoded by the XRCC6 gene) and Ku80 ( Ku genes play a key role in the non-homologous end-joining pathway. We have identified Ku70 and Ku80 homologs in the koji molds Aspergillus sojae and Using human and hamster cells, Mari et al.
