EP300 (Histone acetyltransferase p300) is a protein that switches other genes on and off. The public catalogues list it as an oncogene driver, a tumour suppressor, a biomarker and a fusion partner, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Colorectal cancer, Bladder & urothelial cancer, Head and neck squamous cell carcinoma and 5 more. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Functions as a histone acetyltransferase and regulates transcription via chromatin remodeling. Acetylates all four core histones in nucleosomes. Histone acetylation gives an epigenetic tag for transcriptional activation. Mediates acetylation of histone H3 at 'Lys-122' (H3K122ac), a modification that localises at the surface of the histone octamer and stimulates transcription, possibly by promoting nucleosome instability. Mediates acetylation of histone H3 at 'Lys-18' and 'Lys-27' (H3K18ac and H3K27ac, respectively). Also able to acetylate histone lysine residues that are already monomethylated on the same side chain to form N6-acetyl-N6-methyllysine (Kacme), an epigenetic mark of active chromatin associated with increased transcriptional initiation. Location: Cytoplasm; Nucleus; Chromosome (UniProt). Locus 22q13.2 (HGNC).
