Scientific Background :P300 encodes the adenovirus E1A-associated cellular p300 transcriptional co-activator protein (1). P300 is related by sequence to CBP and like CBP can stimulate transcription through activation of CREB. The P300 activity is specifically inhibited by the adenovirus oncoprotein E1A. P300 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. P300 is a components of DRAF1 (double-stranded RNA-activated factor-1), a positive regulator of interferon-stimulated gene transcription that functions as a direct response to viral infection (2).
