A Ku70/Ku80 complex binds initially to two DNA ends at the DSB site, and then recruits a DNA‐dependent protein kinase (DNA‐PKcs), which has not been identified in plants. DNA‐PKcs phosphorylates and activates many proteins, including nuclease and itself. Heterodimers of the 70 and 80 kDa Ku autoantigens (Ku70 and Ku80) activate the DNA‐dependent protein kinase (DNA‐PK). Mutations in any of the three subunits of this protein kinase (Ku70, Ku80 … 2019-5-17 · The Ku70/80 heterodimer protein possesses a ring-shaped structure with high affinity for DSBs. Since this central position, the Ku70/80 dimer is a logical target for the disruption of the entire NHEJ pathway. Surprisingly, specific inhibitors of the Ku70/80 … 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 The Ku70/80 complex recognizes DNA breaks and serves as an essential hub for recruitment of NHEJ components. Here, we describe intramolecular interactions … 2002-12-6 · Human Ku70/80 associates physically with telomerase through interaction with hTERT.

Here, we describe intramolecular … Nonhomologous end joining (NHEJ) is a DNA repair mechanism that religates double-strand DNA breaks to maintain genomic integrity during the entire cell cycle. Our previous studies indicated that the Werner syndrome protein (WRN) interacts with Ku, a heterodimeric factor of 70- and 80-kDa subunits implicated in the repair of double strand DNA breaks. Moreover, we demonstrated that Ku70/80 strongly stimulates and alters WRN exonuclease activity. 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.

Identification of poly(ADP-ribose) polymerase-1 and Ku70/Ku80 as transcriptional regulators of S100A9 gene expression2006Ingår i: BMC Molecular Biology,

Eukaryotic Ku is a heterodimer of two polypeptides, Ku70 (XRCC6) and Ku80 (XRCC5), so named because the molecular weight of the human Ku proteins is around 70 kDa and 80 kDa. The two Ku subunits form a basket-shaped structure that threads onto the DNA end. Together, Ku70 and Ku80 make up the Ku heterodimer, which binds to DNA double-strand break ends and is required for the non-homologous end joining (NHEJ) pathway of DNA repair. It is also required for V(D)J recombination, which utilizes the NHEJ pathway to promote antigen diversity in the mammalian immune system.

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. We have previously reported that WRN interacts with Ku70/80 and this interaction strongly stimulates WRN exonuclease activity. To gain further insight on the function of WRN and its relationship with the Ku
