Ku70 is an evolutionarily conserved protein that has functions in DNA repair and maintenance. It is a heterodimeric protein made up of Ku70 and Ku80.

Size: 609 amino acids Molecular mass: 69843 Da Quaternary structure: Heterodimer composed of XRCC5/Ku80 and XRCC6/Ku70. The dimer associates in a DNA-dependent manner with PRKDC to form the DNA-dependent protein kinase complex DNA-PK, and with the LIG4-XRCC4 complex to form the core of the non-homologous end joining (NHEJ) complex.

Rabbit anti Ku70 antibody recognizes human Ku70, also known as XRCC6, G22P1 or X-ray repair cross-complementing protein 6. Ku70 is involved in repair of double stranded DNA breaks via the non-homologous end joining (NHEJ) pathway. Ku70 forms a heterodimer with Ku80 (Ku70/Ku80), which binds to the ends of broken DNA where it recruits proteins for end-processing and ligation.

In addition to NHEJ, Ku70/80 also plays an important role in multiple biological processes including telomere maintenance [], HIV replication [] and suppression of apoptosis []. Ku70 and Ku80 form a pseudosymmetrical heterodimer with a preformed ring (also called DNA aperture) responsible for sequence‐independent DNA binding.

2021-02-22 · Acetylation modulates DNA-mediated Ku70-dependent IFN-λ1 induction. Ku80 colocalizes with Ku70 during Ku70 translocation from the nucleus to the cytoplasm, but not directly involving in Ku70's cytosolic DNA activity. The third research area is to study the host genetic determinants that affect HIV pathogenesis and progression.

Ku is Knockdown of Ku70 was achieved by transfecting HeLa with Ku70 specific siRNAs (Silencer® select Product # S5455, S5457). Western blot analysis (Fig. a) was performed using Nuclear enriched extracts from the Ku70 knockdown cells (lane 3), non-targeting scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1).

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. Royaltyn eller avgiften ska då i stället redovisas på KU10.

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 vitro, Ku70 -/- mouse fibroblasts displayed an increased rate of sister chromatid exchange and a high frequency of spontaneous neoplastic transformation. In vivo, Ku70 -/- mice, known to be defective in B- but not T-lymphocyte maturation, developed thymic and disseminated T-cell lymphomas at a mean age of 6 months with CD4+/CD8+ tumor cells. Ku70 (also known as XRCC6) is a eukaryotic protein that is involved in the repair of DNA double-strand breaks by non-homologous end-joining [ 1, 2 ] Ku is a heterodimer of approximately 70kDa and 80kDa subunits The Ku70/Ku80 heterodimer has ATP-dependent DNA helicase activity and functions as the DNA-binding regulatory component of DNA-dependent protein kinase (DNA-PK) (6-8). The assembly of the DNA-PK complex at DNA ends is required for nonhomologous end-joining (NHEJ), one mechanism involved in double-stranded DNA break repair and V(D)J recombination (8).
