Rabbit Anti-NFkB, p50 (NF-kB, Nuclear Factor kappa B p50 Subunit, Nuclear Factor of kappa Light Polypeptide Gene Enhancer in B cells 1, NFkB1, DKFZp686C01211, DNA Binding Factor KBF1, EBP-1, KBF1, MGC54151, NF-kappa-B, NF-kB, Nuclear Factor kappa B DNA Binding Subunit)
The NFkB family of induced-activated transcription factors are dimers comprised of members of the NFkB /rel protein family. Activation of NFkB is induced by a remarkably large number of stimuli including viruses, TNF, IL-1, PMA , LPS, UV light, and others. In most cell types, NFkB is present in the cytoplasm as a 50kD (p50) subunit and a 65kD (p65, rel A) subunit. In unstimulated cells, nuclear localization signals present on p65 are masked by members of the IkB family of inhibitory proteins. Subsequent to cell stimulation, IkB undergoes phosphorylation, ubiquitination and degradation by a proteosomedependant pathway, allowing nuclear translocation of the active dimeric NFkB transcription factor. In the nucleus, NFkB binds to consensus sequences where, along with other co-factors, it participates in activating or enhancing the expression of specific genes.
