Human Gene KAT2A (uc002hyx.2) Description and Page Index
  Description: Homo sapiens K(lysine) acetyltransferase 2A (KAT2A), mRNA.
RefSeq Summary (NM_021078): KAT2A, or GCN5, is a histone acetyltransferase (HAT) that functions primarily as a transcriptional activator. It also functions as a repressor of NF-kappa-B (see MIM 164011) by promoting ubiquitination of the NF-kappa-B subunit RELA (MIM 164014) in a HAT-independent manner (Mao et al., 2009 [PubMed 19339690]).[supplied by OMIM, Sep 2009].

DESCRIPTION: RecName: Full=Histone acetyltransferase KAT2A; EC=; AltName: Full=General control of amino acid synthesis protein 5-like 2; AltName: Full=Histone acetyltransferase GCN5; Short=HsGCN5; AltName: Full=Lysine acetyltransferase 2A; AltName: Full=STAF97;
FUNCTION: Functions as a histone acetyltransferase (HAT) to promote transcriptional activation. Acetylation of histones gives a specific tag for epigenetic transcription activation. Has significant histone acetyltransferase activity with core histones, but not with nucleosome core particles. 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. Component of the ATAC complex, a complex with histone acetyltransferase activity on histones H3 and H4.
CATALYTIC ACTIVITY: Acetyl-CoA + [histone] = CoA + acetyl- [histone].
SUBUNIT: Interacts with EP300, CREBBP and ADA2. Component of the TFTC-HAT complex, at least composed of TAF5L, TAF6L, TAF3, TADA3L, SUPT3H/SPT3, TAF2/TAFII150, TAF4/TAFII135, TAF5/TAFII100, KAT2A/GCN5L2, TAF10 and TRRAP. Interacts with TRRAP. Component of the STAGA transcription coactivator-HAT complex, at least composed of SUPT3H, KAT2A, SUPT7L, TAF5L, TAF6L, TADA3L, TAD1L, TAF10, TAF12, TRRAP and TAF9. The STAGA core complex is associated with a subcomplex required for histone deubiquitination composed of ATXN7L3, ENY2 and USP22. Interacts with and acetylates HIV-1 Tat. Component of the ADA2A-containing complex (ATAC), composed of CSRP2BP, KAT2A, TADA2L, TADA3L, ZZ3, MBIP, WDR5, YEATS2, CCDC101 and DR1. In the complex, it probably interacts directly with CSRP2BP, MBIP and WDR5.
TISSUE SPECIFICITY: Expressed in all tissues tested, with most abundant expression in ovary.
SIMILARITY: Belongs to the GCN5 family.
SIMILARITY: Contains 1 bromo domain.
SIMILARITY: Contains 1 N-acetyltransferase domain.

ModBase Predicted Comparative 3D Structure on Q92830
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
