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

Detta undertryckte sedan rekryteringen av KU70 och KU80, båda nyckelproteinerna för NHEJ, till DSB-sidorna. Ablationen av CBP / p300 försämrade också

Recently, a DNA-sensing function was reported for Ku70/80… DNA ends were in dynamic equilibrium with Ku70/80 in solution, showing that NHEJ complex assembly is reversible. 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.

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. 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 2006-12-5 2013-12-5 The Ku70/80 heterodimer is a key-player in the NHEJ pathway and binds to DNA termini with high affinity, where it helps to protect DNA ends from degradation and to recruit other NHEJ factors 2011-4-1 Ku70/80 Drives DNA-PKcs and PARP1 to Promote CCL3 and CCL5 Expression. As mentioned earlier, the Ku70/80 complex is known for its DNA repair activities, which also require DNA-PKcs .

Moreover, Ku has been reported to associate with hTERT and telomerase activity . However, the precise biological consequence, the biochemical nature of these interactions and the role of DNA-PK in telomere maintenance remain unknown.
