Mouse Anti-p300 (CREBBP/EP300 Inhibitory Protein 1, Cyclic AMP Responsive Enhancer Binding Protein, EP300: E1A Binding Protein p300, EP300, RB and P300 Binding Protein EID 1, Retinoblastoma Protein Associated Protein)
p300 is a relatively stable, ubiquitously expressed, nuclear phosphoprotein which is conserved among a variety of mammalian species. It is actively synthesized and phosphorylated in both quiescent and proliferating cells.
Cyclic AMP-responsive enhancer binding protein (CREB) binding protein (CBP) and p300 are closely related transcriptional coactivators and have been shown to directly interact with many different DNA-binding transcription factors including nuclear hormone receptors, CREB, c-Fos, C-Jun/v-Jun, c-Myb/v-Myb, TFIIB and MyoD. Both CBP and p300 have been shown to display histone acetyltransferase (HAT) activity, capable of acetylating all four core histone particles in nucleosomes. As a result of HAT activity, it has been suggested CBP and p300 may play a direct role in activating chromatin for transcription.
