Flow Cytometry (Intracellular) - Anti-Ku80 antibody [EPR3468] (AB80592)
Intracellular Flow Cytometry analysis of HeLa (human cervix adenocarcinoma) cells labeling Ku80 with unpurified ab80592 at 1/20 dilution (10ug/mL) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluorr® 488) (1/2000 dilution) was used as the secondary antibody. Rabbit monoclonal IgG (Black) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) were used as the unlabeled control.

Biological function summary
The Ku80 protein executes an important role in maintaining cellular stability by participating in the non-homologous end joining (NHEJ) pathway. Ku80 forms a complex with DNA-PKcs (DNA-dependent protein kinase catalytic subunit) which activates the kinase to phosphorylate itself and other proteins facilitating the repair of DSBs. Its expression is significant in tissues that undergo high rates of cellular turnover and are experienced with DNA damage where the DNA repair mechanisms are important for regular cell cycle progression.
Pathways
DNA repair and V(D)J recombination are principal domains where Ku80 shows its influence. In the context of DNA repair Ku80's partnership with DNA-PKcs as part of the NHEJ repair pathway is fundamental in fixing DNA damage from environmental insults or normal cellular metabolism. In the immune development process through V(D)J recombination Ku80 partners with other proteins like the Artemis complex to perform programmed DNA rearrangements required for the diversity of immune receptors.
