Western blot analysis on Hela cell lysates using anti-Phospho-IkappaB-alpha (pS32) RabMAb (Cat. #AJ1389d). Cells were either (A) untreated (B) treated with Calyculin A and TNF-a
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
Tissue Specificity
A phospho specific peptide corresponding to residues surrounding Serine 32 of human IkappaB-alpha was used as an immunogen.
Cellular Localization
Cytoplasm. Nucleus. Note=Shuttles between the nucleus and the cytoplasm by a nuclear localization signal (NLS) and a CRM1-dependent nuclear export (By similarity)
