Target
-
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. -
Post-translational
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 - Anti-IKB alpha antibody [6A920] (ab12134)Lane 1: Wild type HAP1 whole cell lysate (20 µg)
Lane 2: IKB alpha knockout HAP1 whole cell lysate (20 µg)

Lane 4: HepG2 whole cell lysate (20 µg)Lanes 1 - 4: Merged signal (red and green). Green - ab12134 observed at 38 kDa. Red - loading control, ab176560, observed at 50 kDa.
ab12134 was shown to specifically react with IKB alpha in wild type cells as signal was lost in IKB alpha knockout cells. Wild-type and IKB alpha knockout samples were subjected to SDS-PAGE. Ab12134 and ab176560 (Rabbit anti alpha Tubulin loading control) were incubated overnight at 4°C at 1 ug/ml and 1/10000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed ab216772 and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed ab216777 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.

The tissue was formaldehyde fixed and a heat mediated antigen retrieval step in citrate buffer was performed. The tissue was blocked in serum before incubation with the primary antibody for 30 minutes at 22°C. An HRP conjugated goat anti-mouse antibody was used as the secondary.

ab12134 detects both phosphorylated and non-phosphorylated forms of IKB alpha by Western blot. Jurkat cells (1E7) were treated for indicated time periods with 10 nm/ml PMA, 1 µM ionomycin and ab12134 (1/10000 dilution). 10 µl of cytoplasmic (C) and nuclear extract (N) were resolved on a 8.75% SDS-PAGE and transferred to Immobilon membrane.µ µ
