The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
The peptide is specifically recognized by IkBa (Tyr-42) phospho-specific antibody (ab24783) in ELISA, and has been shown to
block the reactivity of ab24783 during Western blot. In addition, the peptide is recommended for use in blocking ab24783
reactivity in immunocytochemistry.
This product is an active protein and may elicit a biological response in vivo, handle with caution.

Nuclear factor of kappa light polypeptide gene enhancer in B cells inhibitor alpha
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.
Ectodermal dysplasia, anhidrotic, with T-cell immunodeficiency autosomal dominant
Belongs to the NF-kappa-B inhibitor family. Contains 5 ANK repeats.
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.
Cytoplasm. Nucleus. Shuttles between the nucleus and the cytoplasm by a nuclear localization signal (NLS) and a CRM1-dependent nuclear export.
