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.

ab7217 staining IKB alpha in human stomach tissue sections by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Tissue was fixed with formaldehyde and a heat mediated antigen retrieval step was performed using 10mM citrate buffer pH 6.0. Samples were then blocked with 5% serum for 1 hour at 23°C followed by incubation with the primary antibody, at a 1/200 dilution, for 1 hour at 23°C. An undiluted HRP-conjugated goat anti-rabbit IgG polyclonal was used as secondary antibody.
Whole cell lysate from HeLa cells used at total protein input 200µg. Immunoprecipitation step performed using Protein A/G. Diluted at 2µg/mg lysate, 16 hours at 4°C in NETN buffer.
ab7217 used as western blot antibody at a 1/1000 dilution to confirm successful Immunoprecipitation.
ab7217 staining IKB alpha in human stomach tissue sections by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections). Tissue was fixed with acetone and then blocked with 5% serum for 1 hour at 23°C followed by incubation with the primary antibody at a 1/200 dilution for 1 hour at 23°C. An undiluted HRP-conjugated goat anti-rabbit IgG polyclonal was used as secondary antibody.
ab7217 staining IKB alpha in NIH3T3 mouse fibroblast cells by Immunocytochemistry/ Immunofluorescence. The cells were fixed in formaldehyde, permeabilised in 0.025% Triton X and then blocked using 5% serum for 1 hour at 23°C. Samples were then incubated with primary antibody at 1/500 for 1 hour at 23°C. The secondary antibody used was a goat anti-rabbit IgG conjugated to Alexa Fluor® 568 (red) used at a 1/1000 dilution.
