The transcriptional coactivator CBP/p300 associates with through 2 sites, an N-terminal domain that interacts with the C-terminal region of unphosphorylated p65, and a second domain that only interacts with p65 phosphorylated on serine-276. Phosphorylation by PKA both weakens the interaction between the N- and C-terminal regions of p65 and creates an additional site for interaction with CBP/p300. Therefore, PKA regulates the transcriptional activity of NF-kappa-B by modulating its interaction with CBP/p300.The p50 (NFKB1)/p65 (RELA) heterodimer is the most abundant form of NFKB. The NFKB complex is inhibited by I-kappa-B proteins (NFKBIA or NFKBIB ), which inactivate NFKB by trapping it in the cytoplasm.
Bovine Transcription factor p65 (RELA) ELISA Kit employs a two-site sandwich ELISA to quantitate RELA in samples. An antibody specific for RELA has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyRELA present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for RELA is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of RELA bound in the initial step. The color development is stopped and the intensity of the color is measured.
