Histone Acetyltransferase

The histone acetyltransferase (HAT) enzymes p300 and CBP are closely related paralogs that serve as transcriptional coactivators. The p300 and CBP catalyze the acetylation of Lys residues in histones and other proteins. Serving as transcriptional coactivators, p300 and CBP participate in numerous ways to regulate cell growth, differentiation, and gene expression across many organ systems and physiologic pathways. Dysregulation of p300/CBP by mutation, altered expression, or other mechanisms has been linked to disease states, including various malignancies such as acute leukemias and prostate cancer. Furthermore, p300/CBP is critical in development as evidenced by the genetic disorder Rubinstein-Taybi syndrome, which occurs with loss of function mutations in single alleles of either p300 or CBP.

Inhibitors of p300/CBP HAT activity have been developed and are under investigation as therapeutics for a number of diseases.
