Human Ku heterodimeric protein composed of Ku70 and Ku80 subunits plays an important role in the non-homologous end-joining DNA repair pathway as a sensor of double strand DNA breaks. Ku is also ...The eukaryotic Ku protein has key roles in DNA repair and in certain transposition events. Here we show that the Gam protein of phage Mu is conserved in bacteria, has sequence homology with both ...We find that a cDNA clone for the smaller subunit (beta) of YPF1 encodes a 72-kDa protein that has extensive homology to the smaller subunit of the heterodimeric Ku protein (24% identity, 51% ...

Objectives To investigate DNA damage/repair balance and DNA-dependent protein kinase complex in COPD lung and in an animal model of smoking-induced lung damage and to evaluate the effects of oxidative stress on Ku expression and function in human bronchial epithelial cells. Methods Protein expression was quantified …The importance of Ku in DSBR is evident from studies where the Ku protein was deleted in mice. In order to understand the mechanistic and functional aspects of Ku and DNA-PKcs in modulating stress response such as ionizing radiation (IR) and radio mimetic chemicals, murine knockout experiments generating Ku86−/−, Ku70−/−, and DNA-PKcs−/− cell lines and homozygous mutant mice were ...The Ku antigen is a DNA-associated nuclear protein recognized by sera from patients with autoimmune diseases.

Protein Modeling—The SPOCK modeling program (25) was used to dock the crystal structures of the core nucleosome (Protein Data Bank accession 1AOI) and Ku bound to DNA (accession 1JEY) by multiple alignments of the phosphodiester backbone of residues 2-12 in chain C of 1JEY with the backbone of 10 consecutive residues in chain I of 1AOI.Iterative alignments were made, advancing target ...Ku is a heterodimeric protein composed of approximately 70- and approximately 80-kDa subunits (Ku70 and Ku80) originally identified as an autoantigen recognized by the sera of patients with autoimmune diseases. Ku has high binding affinity for DNA ends and that is why originally it was known as a DNA end binding protein, but now it is known to ...We propose that 5’ adenosine monophosphate-activated protein kinase (AMPK) ...

Effects of PGC-1alpha on TNF-alpha-induced MCP-1 and VCAM-1 expression and NF-kappaB activation in human aortic smooth muscle and endothelial cells.Bacterial Ku is usually found as a single gene and exists as homodimers. It is much smaller than the eukaryotic Ku proteins and does not include the vWA and SAP domains that make Ku 70/80 distinct. These additional domains allow eukaryotic Ku to behave as a scaffold protein and interact with the variety of factors in the more complex NHEJ system.

The carboxyl terminus of WRNp interacts physically with the Ku86/70 complex. The exonuclease domain of WRNp is located in the amino-terminal end of the protein and the helicase/ATPase domain in its central part (Fig. (Fig.1A). 1 A). Because the carboxyl terminus (C-WRNp) of WRNp lacks homology to known functional domains, we searched for interactions with this portion of the protein.Studying molecular interactions of nucleic acid binders, affinity vs. avidity, and ternary complexes with the heliX+ biosensor. The I2BC PIM platform proposed the swithSENSE technology since 2017 that uses nanolevers bound on a gold surface to measure protein interactions in an approach highly complementary to other surface …The DNA-dependent protein kinase: requirement for DNA ends and association with Ku antigen.

Ku binds the broken DNA end and recruits other proteins to facilitate the processing and ligation of the broken end. While Ku interacts with many proteins involved in DNA damage/repair-related functions, few interactions have been mapped to the N-terminal von Willebrand A (vWA) domain, a predicted protein interaction domain.These results showed that it was the Ku protein that formed complexes with DNA probe and the antibodies bound to Ku protein-DNA complexes did not affect the DNA-binding activity of the protein. No effect on DNA binding was detected after preincubation of Ku protein with a non-related monoclonal antibody specific for a 250-kDa membrane antigen ...

Both of these components are involved in DNA double-strand break repair, but it has not been clear if they function indirectly, by sensing DNA damage and activating other factors, or if they are more directly involved in the processing and rejoining of DNA breaks. 2. The ubiquitin-proteasome system. The UPS contains both substrate-recruiting and substrate-degrading machinery (Dahlmann, 2007).The central element of this intricate system, the proteasome, is a highly abundant and stable cellular protein complex (Liggett et al., 2010).A number of proteasome-associated proteins have been identified, which may either enhance or suppress UPS-mediated ...
