p300/CBP

p300 and CBP are specialized proteins that help control gene activity in our cells. They act like molecular switches, attaching chemical groups to other proteins, including DNA-associated proteins called histones. This process, known as acetylation, makes it easier for genes to be turned on or off. By modifying chromatin structure, p300 and CBP influence which genes are active, playing crucial roles in processes like cell growth, development, and response to signals. They are essential for normal cell function and are linked to various health conditions when their activity is disrupted.
