description:
The NF-KappaB family of transcription factors plays a critical role in numerous cellular processes, particularly the immune response. Our understanding of how the different NF-kappaB subunits act coordinately to regulate gene expression is based on a limited set of genes. We used genome-scale location analysis to identify targets of all five NF-kappaB proteins before and after stimulation of monocytic cells with bacterial lipopolysaccharide (LPS). In unstimulated cells, p50 and p52 bound to a significant number of gene promoters. p50 occupied genes together with RNA polymerase II and defined a set of genes to which other NF-kappaB proteins bound after LPS induction. In stimulated cells, genes bound by multiple NF-kappaB subunits exhibited the greatest increases in RNA polymerase II occupancy and gene expression. This study identifies novel NF-kappaB target genes, reveals how the different NF-kappaB proteins coordinate their activity and maps transcriptional regulatory networks that underlie the host response to infection.
