Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.
Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|WB||1/500. Detects a band of approximately 38 kDa.|
FunctionInhibits the activity of dimeric NF-kappa-B/REL complexes by trapping REL dimers in the cytoplasm through masking of their nuclear localization signals. On cellular stimulation by immune and proinflammatory responses, becomes phosphorylated promoting ubiquitination and degradation, enabling the dimeric RELA to translocate to the nucleus and activate transcription.
Involvement in diseaseEctodermal dysplasia, anhidrotic, with T-cell immunodeficiency autosomal dominant
Sequence similaritiesBelongs to the NF-kappa-B inhibitor family.
Contains 5 ANK repeats.
modificationsPhosphorylated; disables inhibition of NF-kappa-B DNA-binding activity. Phosphorylation at positions 32 and 36 is prerequisite to recognition by UBE2D3 leading to polyubiquitination and subsequent degradation.
Sumoylated; sumoylation requires the presence of the nuclear import signal. Sumoylation blocks ubiquitination and proteasome-mediated degradation of the protein thereby increasing the protein stability.
Monoubiquitinated at Lys-21 and/or Lys-22 by UBE2D3. Ubiquitin chain elongation is then performed by CDC34 in cooperation with the SCF(FBXW11) E3 ligase complex, building ubiquitin chains from the UBE2D3-primed NFKBIA-linked ubiquitin. The resulting polyubiquitination leads to protein degradation. Also ubiquitinated by SCF(BTRC) following stimulus-dependent phosphorylation at Ser-32 and Ser-36.
Deubiquitinated by porcine reproductive and respiratory syndrome virus Nsp2 protein, which thereby interferes with NFKBIA degradation and impairs subsequent NF-kappa-B activation.
Cellular localizationCytoplasm. Nucleus. Shuttles between the nucleus and the cytoplasm by a nuclear localization signal (NLS) and a CRM1-dependent nuclear export.

Western blot analysis of A431 cells treated with pervanadate (1 mM) for 30 minutes (30 ug/lane). Blots were probed with anti-IkappaBalpha (lane 1), anti-phospho-IkappaBalpha?(Tyr-42) (ab24783; lanes 2-5), or anti-phospho-IkappaBalpha (Tyr-305) (ab24784; lanes 6-9). Both anti-phospho-IkappaBalpha (Tyr-42) and anti-phospho-IkappaBalpha (Tyr-305) were used in the presence of no blocking peptide (lane 2 & 6), phospho-IkappaBalpha (Tyr-42) peptide (lane 3 & 8), phospho-IkappaBalpha (Tyr-305) peptide (lane 4 & 7), or BSA conjugated to phospho-tyrosine (lane 5 & 9). Peptides and BSA-pTyr were used at 1 ug/ml.
