Bromodomain-containing protein 4-independent transcriptional activation by autoimmune regulator (AIRE) and NF-κB.

Autoimmune regulator (AIRE) and nuclear factor-κB (NF-κB) are transcription factors (TFs) that direct the expression of individual genes and gene clusters. Bromodomain-containing protein 4 (BRD4) is an epigenetic regulator that recognizes and binds to acetylated histones. BRD4 also has been reported to promote interactions between the positive transcription elongation factor b (P-TEFb) and AIRE or P-TEFb and NF-κB subunit p65. Here, we report that AIRE and p65 bind to P-TEFb independently of BRD4. JQ1, a compound that disrupts interactions between BRD4 and acetylated proteins, does not decrease transcriptional activities of AIRE or p65. Moreover, siRNA-mediated inactivation of BRD4 alone or in combination with JQ1 had no effects on AIRE- and NF-κB-targeted genes on plasmids and in chromatin and on interactions between P-TEFb and AIRE or NF-κB. Finally, ChIP experiments revealed that recruitment of P-TEFb to AIRE or p65 to transcription complexes was independent of BRD4. We conclude that direct interactions between AIRE, NF-κB, and P-TEFb result in efficient transcription of their target genes.
