'''NMR Structure of IBiD, A Domain of CBP/p300'''<br />


==Overview==
==NMR Structure of IBiD, A Domain of CBP/p300==
The transcriptional coactivators CBP and p300 are critical regulators of, metazoan gene expression. They associate with many different DNA-bound, transcription factors through small, conserved domains. We have identified, a compactly folded 46 residue domain in CBP and p300, the IRF-3 binding, domain (IBiD), and we have determined its structure by NMR. It has a, helical framework containing an apparently flexible polyglutamine loop, that participates in ligand binding. Spectroscopic data indicate that, induced folding accompanies association of IBiD with its partners, which, exhibit no evident sequence similarities. We demonstrate the significance, both in vitro and in vivo of interactions between IBiD and a number of, diverse partners. Thus, IBiD is an important contributor to signal, integration by CBP and p300.

== Function ==
[https://www.uniprot.org/uniprot/CBP_MOUSE CBP_MOUSE] Acetylates histones, giving a specific tag for transcriptional activation. Also acetylates non-histone proteins, like NCOA3 and FOXO1. Binds specifically to phosphorylated CREB and enhances its transcriptional activity toward cAMP-responsive genes. Acts as a coactivator of ALX1 in the presence of EP300 (By similarity).<ref>PMID:10207073</ref> <ref>PMID:11701890</ref> <ref>PMID:15220471</ref> <ref>PMID:16287980</ref>

== Publication Abstract from PubMed ==
The transcriptional coactivators CBP and p300 are critical regulators of metazoan gene expression. They associate with many different DNA-bound transcription factors through small, conserved domains. We have identified a compactly folded 46 residue domain in CBP and p300, the IRF-3 binding domain (IBiD), and we have determined its structure by NMR. It has a helical framework containing an apparently flexible polyglutamine loop that participates in ligand binding. Spectroscopic data indicate that induced folding accompanies association of IBiD with its partners, which exhibit no evident sequence similarities. We demonstrate the significance both in vitro and in vivo of interactions between IBiD and a number of diverse partners. Thus, IBiD is an important contributor to signal integration by CBP and p300.
