Target

  • Function
    Acts as part of the IKK complex in the conventional pathway of NF-kappa-B activation and phosphorylates inhibitors of NF-kappa-B thus leading to the dissociation of the inhibitor/NF-kappa-B complex and ultimately the degradation of the inhibitor. As part of the non-canonical pathway of NF-kappa-B activation, the MAP3K14-activated CHUK/IKKA homodimer phosphorylates NFKB2/p100 associated with RelB, inducing its proteolytic processing to NFKB2/p52 and the formation of NF-kappa-B RelB-p52 complexes. Also phosphorylates NCOA3. Phosphorylates 'Ser-10' of histone H3 at NF-kappa-B-regulated promoters during inflammatory responses triggered by cytokines.
  • Tissue specificity
    Widely expressed.
  • Involvement in disease
    Defects in CHUK are the cause of cocoon syndrome (COCOS) [MIM:613630]; also known as fetal encasement syndrome. COCOS is a lethal syndrome characterized by multiple fetal malformations including defective face and seemingly absent limbs, which are bound to the trunk and encased under the skin.
  • Sequence similarities
    Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. I-kappa-B kinase subfamily.
    Contains 1 protein kinase domain.
  • Post-translational
    modifications
    Phosphorylated by MAP3K14/NIK, AKT and to a lesser extent by MEKK1, and dephosphorylated by PP2A. Autophosphorylated.
    Acetylation of Thr-179 by Yersinia yopJ prevents phosphorylation and activation, thus blocking the I-kappa-B signaling pathway.
  • Cellular localization
    Cytoplasm. Nucleus. Shuttles between the cytoplasm and the nucleus.

  • ICC/IF image of ab38515 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab38515, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Answer

Thank you for contacting us regarding ab38515.

I have received the following additional information from the lab:

This target containing leucine zipper associates with many proteins. It is posible that theband is dimerization. The leucine zipper is important to allow homo- and hetero-dimerization. Add DTT to lysis buffer as we find this helps.

I hope this information is helpful. Please do not hesitate to contact us if you have any additional questions.

Answer

Thank you for your enquiry.

I can confirm that as ab105923IKK alpha antibodyhas not specifically been raised against a phosphorylated residue of the protein, it is therefore likely to detect both phosphorylated and non phosphorylated forms of the protein.

We do have the following antibodies that detect some of the phosphorylated residues specifically. I can recommend to review the datasheets for further details and to select one tested in the species you wil be using.
