Function

Serine/threonine-protein kinase that acts as a molecular sensor for DNA damage. Involved in DNA nonhomologous end joining (NHEJ) required for double-strand break (DSB) repair and V(D)J recombination. Must be bound to DNA to express its catalytic properties. Promotes processing of hairpin DNA structures in V(D)J recombination by activation of the hairpin endonuclease artemis (DCLRE1C). The assembly of the DNA-PK complex at DNA ends is also required for the NHEJ ligation step. Required to protect and align broken ends of DNA. May also act as a scaffold protein to aid the localization of DNA repair proteins to the site of damage. Found at the ends of chromosomes, suggesting a further role in the maintenance of telomeric stability and the prevention of chromosomal end fusion. Also involved in modulation of transcription. Recognizes the substrate consensus sequence [ST]-Q. Phosphorylates 'Ser-139' of histone variant H2AX/H2AFX, thereby regulating DNA damage response mechanism. Phosphorylates DCLRE1C, c-Abl/ABL1, histone H1, HSPCA, c-jun/JUN, p53/TP53, PARP1, POU2F1, DHX9, SRF, XRCC1, XRCC1, XRCC4, XRCC5, XRCC6, WRN, MYC and RFA2. Can phosphorylate C1D not only in the presence of linear DNA but also in the presence of supercoiled DNA. Ability to phosphorylate p53/TP53 in the presence of supercoiled DNA is dependent on C1D.
Sequence similarities

Belongs to the PI3/PI4-kinase family.
Contains 1 FAT domain.
Contains 1 FATC domain.
Contains 2 HEAT repeats.
Contains 1 PI3K/PI4K domain.
Contains 3 TPR repeats.
Post-translational
modifications

Phosphorylated upon DNA damage, probably by ATM or ATR. Autophosphorylated on Thr-2609, Thr-2638 and Thr-2647. Thr-2609 is a DNA damage-inducible phosphorylation site (inducible with ionizing radiation, IR). Autophosphorylation induces a conformational change that leads to remodeling of the DNA-PK complex, requisite for efficient end processing and DNA repair.
S-nitrosylated by GAPDH.

Western blot - Anti-DNA PKcs antibody [Y393] (ab32566)

Lane 1: Wild-type HAP1 cell lysate (20 µg)
Lane 2: DNA PKcs knockout HAP1 cell lysate (20 µg)
Lane 3: K562 cell lysate (20 µg)
Lane 4: SH-SY5Y cell lysate (20 µg)
Lanes 1 - 4: Merged signal (red and green). Green - ab32566 observed at 470 kDa. Red - loading control, ab7291, observed at 52 kDa.

ab32566 was shown to specifically react with DNA PKCs in wild-type HAP1 cells. No band was observed when DNA PKcs knockout samples were examined. Wild-type and DNA PKCs knockout samples were subjected to SDS-PAGE. ab32566 and ab7291 (loading control to alpha tubulin) were diluted 1/1000 and 1/10,000 and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10,000 dilution for 1 hour at room temperature before imaging.

Question

Purchasing 1549-1 lot YG021806C and 1579-1 lot YC120107R
The Epitomics datasheets says the lot numbers can be used to find the isotype control of the correct concentration.
Please confirm which isotype controls.

Asked on Oct 25 2012

Answer

Thank you for contacting us and your interest in our products.

Epitomics did offer isotype controls specific for different lots of antibody purchased. This was providing the antibody at the same concentration as the antibody to be tested. We do not currently have this available from our catalogue. We do however have a rabbit monoclonal isotype control. This can be viewed from the following link:

www.abcam.com/ab125938

This is provided at a concentration of 0.2 mg/mL.

I hope this information has been of help. If I can be of any further assistance, please do not hesitate to let me know.
