CEBPB

(redirected from NF-IL6)

CEBPB

A gene on chromosome 20q13.1 that encodes a transcription factor which binds as a homodimer to various DNA regulatory regions, and as a heterodimer to CEBP-beta, CEBP-delta and CEBP-gamma. CEBP-beta binds to regulatory regions—e.g., IL-1 response element in IL-6 gene—of genes involved in immune and inflammatory responses.

Although NF-[kappa]B is thought of as a genetic switch that can control early-response gene expression, the synergistic interaction of NF-[kappa]B with other transcription factors such as Stat (14, 15), Ap-1 (16), cAMP-response element binding protein (17), nuclear factor AT (18, 19), and NF-IL6 (20) is required to achieve a purposeful induction of a particular gene.
There is also some evidence to show that occupied estrogen receptors inhibit IL-6 gene expression by preventing the binding of NF-[kappa]B and NF-IL6 transcription factors to their respective binding sites in the IL-6 gene promoter (69).
