De CREB-bindingseiwit domeinen, KIX, TAZ1 en TAZ2 binden elk stevig aan de beide transactivatie domeinen 9aaTADs van de transcriptiefactor p53.
Functie
Het CREBBP-gen is betrokken bij de transcriptionele coactivatie van veel verschillende transcriptiefactoren. Het werd voor het eerst geïsoleerd als een nucleuseiwit dat zich bindt aan het cAMP-reactie-elementbindend eiwit (CREB). Het gen speelt een kritische rol bij de embryonale ontwikkeling, controle van de groei en homeostase door te koppelen aan chromatine en het zo geschikt te maken voor de herkenning van de transcriptiefactor. Het door het gen gecodeerde eiwit heeft een eigen histon-acetyltransferase activiteit en werkt ook ondersteunend voor het stabiliseren van bijkomende eiwitinteracties met het transcriptieomplex. Het eiwit acetyleert zowel histonen als non-histon eiwitten. Het eiwit heeft zeer sterk vergelijkbare regio's met het eiwit EP300 en hun bromodomein, cysteïne-histidine-rijke regio's en het histonacetyltransferasedomein.
