Ku70-Ku80 Heterodimer, Human (sf9, His)

Ku70 is a single-stranded DNA-dependent ATP-dependent helicase that plays a key role in DNA nonhomologous end joining (NHEJ) and is central to double-strand break repair and V(D)J recombination. As a DNA helicase II complex, it has a cell cycle-dependent preference for double-stranded DNA fork ends in the 3'-5' direction, recognizing and binding to broken DNA ends during NHEJ, protecting them from resection. Ku70-Ku80 Heterodimer Protein, Human (sf9, His) is a recombinant protein dimer complex containing human-derived Ku70-Ku80 Heterodimer protein, expressed by Sf9 insect cells , with N-His labeled tag. Ku70-Ku80 Heterodimer Protein, Human (sf9, His), has molecular weight of ~70 & 85 kDa, respectively.
