Summary
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]

Protein interactions

Protein Gene Interaction Pubs
Tat tat The K19A, K41Q, and K51A mutations decrease HIV-1 Tat binding to hGCN5, whereas the K50Q and K50R mutations increase the binding PubMed
tat hGCN5 enhances HIV-1 Tat-mediated transactivation of the HIV-1 LTR promoter PubMed
tat HIV-1 Tat is acetylated by hGCN5 on lysine's 50 and 51 PubMed
tat Binding of HIV-1 Tat to hGCN5 is mediated by amino acids 20-48 of Tat (includes cysteine rich, core, and minimal activation domains of Tat) and by amino acids 111-151 (histone acetyltransferase domain) and 389-476 (bromodomain) of hGCN5 PubMed
tat HIV-1 Tat inhibits the histone acetyltransferase and transcriptional activation activities of hGCN5, an effect mediated by amino acids 86-101 of Tat PubMed
tat HIV-1 Tat recruits hGCN5, as well as other known cellular acetyltransferases, to the HIV-1 LTR promoter, an effect involved in the acetylation of histones H3 and H4, and HIV-1 transcriptional activation PubMed
integrase gag-pol HIV-1 IN binds to GCN5, which requires the C-terminal region (amino acids 244-288) of IN PubMed
gag-pol GCN5 acetylates lysine's 258, 264, 266, and 273 of HIV-1 IN and stimulates the catalytic activity of IN PubMed

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
