Simplified, Ku70/80 complex is a sensor of DSBs that initiates the assembly of C-NHEJ complex to restore integrity of a DNA molecule. In fact, the role of Ku70/80 proteins is highly complex and integrates different aspects of DNA repair.

Binds to naturally occurring chromosomal ends, and therefore provides chromosomal end protection. Required also for telomere recombination to repair telomeric ends in the absence of telomerase. ku70, of the ku70/ku80 heterodimer, binds to the stem loop of tlc1, the RNA component of telomerase. Required for mating-type switching (By similarity).

InterPro provides functional analysis of proteins by classifying them into families and predicting domains and important sites. We combine protein signatures from a number of member databases into a single searchable resource, capitalising on their individual strengths to produce a powerful integrated database and diagnostic tool. Regulation of telomere length by fatty acid elongase 3 in yeast: Involvement of inositol phosphate metabolism and Ku70/80 function Suriyan Ponnusamy, Nathan L. Alderson, Hiroko Hama, Jacek Bielawski, James C. Jiang, Rashna Bhandari, Solomon H. Snyder , S. Michal Jazwinski, Besim Ogretmen 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 required for repair. The mechanism of Ku70/80 detachment from the DNA helix after completion of DNA repair is incompletely understood. The genetic disease Fanconi anemia (FA) results from mutations in a series of genes involved in a DNA repair pathway that helps process the damage caused by erroneous chemical cross-links between the two strands of the DNA double helix.

Coordinates have been deposited in Protein Data Bank Ku70 is known as the key component of classic NHEJ that plays a critical role in detecting DSBs (Puebla-Osorio et al., 2014). Thus, in the present study, we focused the specific role of Ku70 in DNA damage caused by F. nucleatum infection. However, another model is clearly needed to explore the role of Ku70/80 heterodimer under F. nucleatum 1999-05-01 Function.

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.

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 . important to the function of Ku70/80 in bringing together the broken DNA ends. The data from Bennett et al. is consistent with the crystal structure as determined by Walker et al.

Ku70, a known nonhomologous end-joining (NHEJ) factor, also functions in tumor suppression, although this molecular mechanism remains uncharacterized. It has been shown that the Ku70/80 protein functions as a heterodimer to repair DSBs, with the two constituents stabilizing each other (Smider et al., 1994).
