General description
This gene encodes the adenovirus E1A-associated cellular p300 transcriptional co-activator protein. It functions as histone acetyltransferase that regulates transcription via chromatin remodeling and is important in the processes of cell proliferation and differentiation. It mediates cAMP-gene regulation by binding specifically to phosphorylated CREB protein. This gene has also been identified as a co-activator of HIF1A (hypoxia-inducible factor 1 alpha), and thus plays a role in the stimulation of hypoxia-induced genes such as VEGF. Defects in this gene are a cause of Rubinstein-Taybi syndrome and may also play a role in epithelial cancer. (provided by RefSeq)

Biochem/physiol Actions
E1A binding protein p300 (p300) and CBP (CREB binding protein) are highly related transcriptional coactivators. Both proteins have been identified through protein interaction assays. In addition to interacting with a variety of cellular factors and oncoproteins, loss of the wild type CBP alleles in isolated tumors suggests that CBP/p300 might serve as tumor suppressors. The ability of p300 to acetylate many transcription factors, including tumor suppressor p53, E2 factor (E2F), transcription factors II E and -F (TFIIE and -F) etc. demonstrates a novel mechanism of targeted p300 regulation of gene expression. Mutations in the gene encoding the protein have been linked to Rubinstein-Taybi syndrome (RSTS).
