Background: Ku70/XRCC6

Ku70 (Lupus Ku autoantigen protein 70; also ATP-dependent DNA helicase 2 subunit 1) is a ubiquitous 70‑75 kDa nuclear protein that serves as a component of the DNA-dependent protein kinase complex DNA-PK. In particular, it heterodimerizes with Ku80 to form a complex that binds DNA ends and select sequences, and which recruits DNA-PKcs for the purpose of phosphorylating multiple chromatin-bound proteins, including p53, Oct-1 and Sp-1. The Ku:DNA-PKcs complex participates in DNA repair, DNA replication, and VDJ recombination. Human Ku70 is 609 amino acids (aa) in length. It contains a Ku core domain (aa 266‑529), a DNA binding motif (aa 268‑274), an NLS (aa 539‑556) and a C-terminal SAP domain (aa 573‑607). There is one potential splice form that shows a deletion of aa 66‑106. Over aa 405‑556, Ku70 shares 83% aa identity with mouse Ku70.
