  • 機能Inhibits 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.
  • 関連疾患Ectodermal dysplasia, anhidrotic, with T-cell immunodeficiency autosomal dominant
  • 配列類似性Belongs to the NF-kappa-B inhibitor family.
    Contains 5 ANK repeats.
  • 翻訳後修飾Phosphorylated; 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.
  • 細胞内局在Cytoplasm. 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.
