The p70/p80 autoantigen is a nuclear complex consisting of two subunits with molecular masses of approximately 70 and 80 kDa. The complex functions as a single-stranded DNA-dependent ATP-dependent helicase. The complex may be involved in the repair of nonhomologous DNA ends such as that required for double-strand break repair, transposition, and V(D)J recombination. High levels of autoantibodies to p70 and p80 have been found in some patients with systemic lupus erythematosus. [provided by RefSeq, Jul 2008]
Antigen Description
Ku70 is a proteinthat, in humans, is encoded by the XRCC6 gene. Together, Ku70 and Ku80 makeup the Ku heterodimer, which binds to DNA double-strand break ends and isrequired for the non-homologous end joining (NHEJ) pathway of DNA repair. Itis also required for V(D)J recombination, which utilizes the NHEJ pathway topromote antigen diversity in the mammalian immune system.
