P300/CBP-associated factor

P300/CBP-associated factor (PCAF) is an enzyme that plays a key role in regulating how genes are turned on or off in our cells. It works by adding small chemical tags to histones, which are proteins around which DNA is wrapped. This process influences gene activity, impacting processes like cell growth, development, and response to the environment. PCAF is involved in controlling gene expression and can affect how cells function, making it important in normal biology and in diseases like cancer.
