ATP-dependent DNA helicase 2 subunit 1 (Ku70) is a single stranded DNA-dependent helicase originally recognized by the sera of patients with autoimmune diseases (1, 2). It plays a key role in multiple nuclear processes such as DNA repair, chromosome maintenance, transcription regulation, and V(D)J recombination (3). Ku70 forms a heterodimer with Ku80 and contributes to genomic integrity through its ability to bind DNA double-strand breaks and facilitate repair by the non-homologous end-joining (NHEJ) pathway (4). The dimer associates in a DNA-dependent manner with PRKDC to form the DNA-dependent protein kinase complex, DNA-PK (1). Together, the Ku70/Ku80 heterodimer and DNA-PKcs are required for V(D)J recombination and DNA double-strand break repair and may also play a role in transcription regulation (5). In addition, the dimer associates with NARG1 to bind to the osteocalcin promoter and activate osteocalcin expression (1).
