      Background InformationP/CAF(sometimes called KAT2B) is a transcription cofactor with a histone acetyltransferase (HAT) activity. Consistent with this protein playing a direct role in transcriptional regulation, P/CAF can acetylate core histones H3 and H4, chromatin proteins HMG17 and HMG I(Y), as well as human immunodeficiency virus Tat, transcription factor MyoD, and general transcription factors TFIIE and TFIIF. A role for P/CAF in cell growth and differentiation is suggested by its interaction in vivo and in vitro with p300/CBP, two large nuclear proteins that bind to sequence-specific factors involved in cell growth/differentiation. A role for P/CAF in cell division is also suggested by data showing that this protein competes with E1A for binding sites in p300/CBP to counteract E1A's mitogenic activity.

      Entrez Gene Number
      Entrez Gene SummarySummary: 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. It has histone acetyl transferase activity with core histones and nucleosome core particles, indicating that this protein plays a direct role in transcriptional regulation. [provided by RefSeq].

      UniProt Number
      UniProt SummaryFUNCTION: Functions as a histone acetyltransferase (HAT) to promote transcriptional activation. Has significant histone acetyltransferase activity with core histones (H3 and H4), and also with nucleosome core particles. Inhibits cell-cycle progression and counteracts the mitogenic activity of the adenoviral oncoprotein E1A. In case of HIV-1 infection, it is recruited by the viral protein Tat. Regulates Tat's transactivating activity and may help inducing chromatin remodeling of proviral genes.

      CATALYTIC ACTIVITY: Acetyl-CoA + [histone] = CoA + acetyl-[histone].

      SUBUNIT STRUCTURE: Interacts with SIRT1. Interacts (unsumoylated form) with NR2C1; the interaction promotes tranactivation activity (By similarity). Interacts with EP300 and CREBBP. Interacts with NCOA1 and NCOA3. Component of a large chromatin remodeling complex, at least composed of MYSM1, KAT2B/PCAF, RBM10 and KIF11/TRIP5. Interacts with NR2C2 (hypophosphorylated and unsumoylated form); the interaction promotes the transactivation activity of NR2C2. Binds to HTLV-1 Tax. Interacts with and acetylates HIV-1 Tat. Interacts with KLF1; the interaction does not acetylate KLF1 and there is no enhancement of its transactivational activity. Interacts with NFE4. Interacts with MECOM.

      SUBCELLULAR LOCATION: Nucleus (By similarity).

      TISSUE SPECIFICITY: Ubiquitously expressed but most abundant in heart and skeletal muscle.

      DOMAIN: The bromodomain mediates binding to HIV-1 Tat.

      SEQUENCE SIMILARITIES: Belongs to the GCN5 family. Contains 1 bromo domain.Contains 1 N-acetyltransferase domain.
