CTC box-binding factor 85 kDa subunit, CTC85, CTCBF, DNA repair protein XRCC5, G22P2, KARP1, Ku autoantigen, 80kDa, Ku80, Ku86 autoantigen related protein 1, KUB2, NFIV,
Ku80 the 80-kilodalton subunit of the Ku complex, also known as ATP-dependant DNA helicase II. A single stranded DNA-dependent ATP-dependent helicase. It functions together with the DNA ligase IV-XRCC4 complex in the repair of DNA double-strand break by non-homologous end joining and the completion of V(D)J recombination events.
