Background Information

The acetyltransferase CREB-binding protein (CREBBP; also known as CBP or KAT2A) and E1A-binding protein P300 (EP300; also known as P300 or KAT2B) are two closely related regulators. Both are widely expressed within and outside the hematopoietic system and serve as tumor activators or suppressors depending on the situation. CREBBP/EP300 regulate various key physiological functions, including cell apoptosis, proliferation and differentiation, DNA repair, and somatic cell reprogramming.
