Ku70 and Ku80 make up the Ku70/80 heterodimer. They are encoded by the Xrcc5 and Xrcc6 genes, respectively, and are highly abundant in both prokaryotes and eukaryotes. The stability of these proteins depends on each other.

Ku70 is a novel Mcl-1 deubiquitinase that could be a potential target for cancer therapy by manipulating Mcl-1 deubiquitination. loss of expression correlates with decreased survival in gall bladder malignancies patients SMAR1-mediated regulation of repair and apoptosis via a complex crosstalk involving Ku70, HDAC6 and Bax. Single-stranded DNA-dependent ATP-dependent helicase. Involved in DNA non-homologous end joining (NHEJ) required for double-strand break repair. When associated with KU80, binds to double-stranded telomeric and non-telomeric DNA sequences, but not to single-stranded DNA. Recognition of DNA double‐strand breaks during non‐homologous end joining is carried out by the Ku70–Ku80 protein, a 150 kDa heterodimer that recruits the DNA repair kinase DNA‐dependent protein kinase catalytic subunit (DNA‐PKcs) to the lesion. In this study, CBP was found to positively regulate the expression of Ku70, and both CBP and Ku70 were found to negatively regulate the expression of NOX2, therefore, mitigating the intracellular The Ku autoantigen is a heterodimer of 70kDa (p70) and ~80kDa (p80) proteins.

The crystal structure of the human Ku heterodimer was determined both alone and bound to a 55-nucleotide DNA element at 2.7 and 2.5 A resolution, respectively. ku70 tert : gl1; ku70; tert: images; None available : phenotypes ; Surovtseva YV, Shakirov EV, Vespa L, Osbun N, Song X, Shippen DE(2007) In contrast to the ku70 mutant, which undergo telomerase-dependent expansion to more than twice the normal length in a single generation, the ku70 tert double mutant displays accelerated telomere shortening and a precocious onset of genome stability. 2021-02-26 · Depletion of CBP and/or Ku70 inhibited cell growth and caused cell death. To understand the roles of CBP and Ku70 in human melanoma cells, we designed and synthesized a set of CBP siRNA and Ku70 Although the ku70 deletion strain was noted to be more sensitive to UV rays than the corresponding wild-type strain, no lethality, severe growth retardation or loss of gene copy numbers could be detected during repetitive rounds of cultivation and induction of heterologous protein production.

Ku70 is an evolutionarily conserved protein that has functions in DNA repair and maintenance [96].

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. Heterodimers of the 70 and 80 kDa Ku autoantigens (Ku70 and Ku80) activate the DNA‐dependent protein kinase (DNA‐PK).

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.
