    Protocol

    Specificity / Sensitivity

    Phospho-NF-κB p65 (Ser276) Antibody detects NF-κB p65 only when phosphorylated at Ser276. It also cross-reacts with the homologous phosphorylated residues in c-Rel (Ser267) and NF-κB1 p105/p50 (Ser337).

    Species Reactivity:

    Human, Mouse, Rat

    The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.

    Species predicted to react based on 100% sequence homology:

    Bovine, Dog, Pig

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser276 of human NF-κB p65. Antibodies are purified by protein A and peptide affinity chromatography.

    Background

    Transcription factors of the nuclear factor κB (NF-κB)/Rel family play a pivotal role in inflammatory and immune responses (1,2). There are five family members in mammals: RelA, c-Rel, RelB, NF-κB1 (p105/p50), and NF-κB2 (p100/p52). Both p105 and p100 are proteolytically processed by the proteasome to produce p50 and p52, respectively. Rel proteins bind p50 and p52 to form dimeric complexes that bind DNA and regulate transcription. In unstimulated cells, NF-κB is sequestered in the cytoplasm by IκB inhibitory proteins (3-5). NF-κB-activating agents can induce the phosphorylation of IκB proteins, targeting them for rapid degradation through the ubiquitin-proteasome pathway and releasing NF-κB to enter the nucleus where it regulates gene expression (6-8). NIK and IKKα (IKK1) regulate the phosphorylation and processing of NF-κB2 (p100) to produce p52, which translocates to the nucleus (9-11).
    Phosphorylation of NF-κB p65 by PKA and/or MSK1 at Ser276 allows for increased interaction with the transcriptional coactivator p300/CBP to further enhance the transcriptional activity of this transcription factor (12-14)
