Active Recombinant Human K (lysine) Acetyltransferase 2B

CBP and p300 are large nuclear proteins that bind to many sequence-specific factors involved in cell growth and/or differentiation, including c-jun and the adenoviral oncoprotein E1A. The protein encoded by this gene associates with p300/CBP. It has in vitro and in vivo binding activity with CBP and p300, and competes with E1A for binding sites in p300/CBP. PCAF belongs to the GCN5/PCAF family of nuclear HATs. The proteins consist of N-terminal and C-terminal domains separated by a deep hydrophobic cleft. The C-terminus contains the HAT domain and a bromodomain, while the Nterminus contains a PCAF-specific domain. Numerous studies indicate that these HATs function as histone-acetylating transcriptional co-activators. Besides histones, PCAF also acetylates non-histone proteins. It has histone acetyl transferase activity with core histones and nucleosome core particles, indicating that this protein plays a direct role in transcriptional regulation.
