Genome-wide comprehensive analysis of human helicases

In fact, the role of Ku70/80 proteins is highly complex and integrates different aspects of DNA repair. 2012-02-10 2013-07-01 2004-07-09 KU70 – Kontrolluppgift – Näringsbidrag och royalty (SKV 2316) På skatteverket.se använder vi kakor (cookies) för att webbplatsen ska fungera på ett bra sätt för dig.

Ku70, a known nonhomologous end-joining (NHEJ) factor, also functions in tumor suppression, although this molecular mechanism remains uncharacterized. It has been shown that the Ku70/80 protein functions as a heterodimer to repair DSBs, with the two constituents stabilizing each other (Smider et al., 1994). Accordingly, these results may be attributed to a decrease in protein levels of both OsKu80 and OsKu70 caused by the down‐regulation of the expression of OsKu80 mRNA in KD‐Ku80 rice calli The Ku70/80 heterodimer binds to DNA ends with high a nity and specificity. The protein forms a ring that can thread onto a DNA end, which explains its inability to bind to circular DNA molecules or internal positions on the chromosome [5].

The connection between the Ku70 level and stabilization of β-catenin merits further investigation, which could shed light on possible ways to enhance pancreatic β-cell proliferation. It is known that Ku70/80 has a high affinity for DNA ends; therefore, to exclude the possibility that the increase in 12/23 regulation was an artifact due to binding and translocation of Ku70/80 into the DNA, we performed experiments with supercoiled circular DNA. Ku70, a known nonhomologous end-joining (NHEJ) factor, also functions in tumor suppression, although this molecular mechanism remains uncharacterized.

2013-05-01 Importantly, to determine downstream mechanisms, epistasis experiments were performed, and data indicated that ELO3 and YKU70/80 share a common pathway for the regulation of telomere length. More specifically, chromatin immunoprecipitation assays revealed that the telomere binding and protective function of YKu80p in vivo was reduced in elo3Delta cells, whereas its non-homologues end-joining … We propose a structural model of the functions of the subunit‐specific C‐terminal domains in the context of the full‐length Ku70–Ku80 protein . The Ku70‐SAP domain changes its position on DNA binding from the base of the α/β domain of Ku80 to a position that might be proximal to the ring in the side of Ku that faces the continuous DNA. Apoptosis is a key tumor suppression mechanism that can be initiated by activation of the proapoptotic factor Bax. The Ku70 DNA end-joining protein has recently been shown to suppress apoptosis by sequestering Bax from mitochondria.

Ku70, to discover the effect of cellular responses to DNA damage in pancreatic β-cells on … Abstract In this study, the ku70 and ku80 homologs from the Aspergillus niger genome were identified and their function was analyzed using targeted mutagenesis. The role of the ku80 gene in non-homologous end-joining (NHEJ) was investigated by calculating the frequency of homolo-gous recombination.

domains in DNA end binding and  Taken together, these data suggest that Ku70/80 plays a role at DSB ends even when HR is the preferred repair pathway. Once Ku recruits DNA-PKcs to the  comprised of two subunits, Ku70 and Ku80, that is best characterized for its central role as the initial DNA end binding factor in the ''classical'' non- homologous  In the first step, Ku70/80 heterodimer binds the DNA ends (the end-binding activity of protein kinase (DNA-PK) to the DSBs, activating its kinase function [1] . The information may be useful in examining the function of the Ku complex, as well Pull-down analysis with cytosolic proteins identified Ku70 and Ku80 as the   16 Apr 2020 Most bacteria and archaea harbor a single KU gene encoding a protein homodimer, while the related KU70 and KU80 genes encode the two  15 Apr 2011 The functional analysis of IFNL1 promoter revealed that To determine the roles of Ku70 and Ku80 in the activation of IFNL1, we applied  29 Aug 2018 For instance, cytoplasmic Ku70 independent of Ku80 suppresses the dimerization of Ku70 and Ku80 and to the nuclear transport function,  In particular, the invention relates to small-molecules which function as inhibitors of Ku70/80 protein and the non-homologous end-joining (NHEJ) pathway, and  The molecular function of Pso2p in DNA repair is unknown, but yeast and In addition, Ku70 and Ku80 null animals have growth defects and premature  So basically edge server plays a role to make the computational decisions ahead of time, sending only filtered data to the cloud, saving both time and money.
