Description

Description: The B33B4WP monoclonal antibody recognizes human NF kappa B (NFkB) p65 subunit when serine 529 is phosphorylated. NFkB, also known as nuclear factor kappa-light chain enhancer of activated B cells, is a ubiquitous transcription factor that regulates the transcription of many genes involved in cell proliferation, apoptosis, development, immunity and cancer. Functional NFkB is a homo- or hetero-dimer composed of 5 members of the NFkB family: p65 (RelA), c-Rel, RelB, p50 (NFkB1, p105 precursor protein), and p52 (NFkB2, p100 precursor protein). The activity of the complex is negatively regulated by binding to IkB inhibitors that sequester NFkB into the cytoplasm, inhibiting its transcriptional activity. NFkB-activating agents like tumor necrosis factor (TNF) alpha, interleukin-1 beta, lipopolysaccharide, camptothecin, and phorbol ester (PMA) induce the phosphorylation and degradation of IkB, leading to the translocation of NFkB to the nucleus where it binds to kB motifs and regulates gene expression. The activity of p65-containing NFkB complexes is positively regulated by phosphorylation of the p65 subunit at serine 529 and/or serine 536. The B33B4WP monoclonal antibody recognizes a single band at 65 kDa in reduced SDS lysates from TNF alpha-stimulated HeLa cells. Applications Reported: This B33B4WP antibody has been reported for use in intracellular staining followed by flow cytometric analysis.

Nuclear factor kB p65 (NF-kB p65) is encoded by the RELA gene and is present on chromosome 11 in humans. NF-kB P65 is also known as RelA (v-rel avian reticuloendotheliosis viral oncogene homolog A) and belongs to the Rel family of proteins. It is one of the two subunits of NF-kB (Nuclear factor kappa-light-chain-enhancer of activated B cells) that heterodimerizes with the other subunits p50 or p52. However, binding of TNF alpha to its cognate receptor phosphorylates IKK which in turn phosphorylates I kB allowing proteasomal degradation of I kB. It specifically plays a key role in transcription of immunoglobulin k (kappa) gene in mature B-lymphoid cells.
