General description
Histone acetyltransferase KAT2A (UniProt: Q92830; also known as EC: 2.3.1.48, General control of amino acid synthesis protein 5-like 2, Histone acetyltransferase GCN5, HsGCN5, Lysine acetyltransferase 2A, STAF97) is encoded by the KAT2A (also known as GCN5, GCN5L2, HGCN5) gene (Gene ID: 2648) in human. Histone acetyltransferase KAT2A belongs to the acetyltransferase family and is expressed in all tissues tested. However, its expression is highest in ovaries. It has three acetyl-CoA-binding regions (aa 579-581; 586-592; 617-620) and one bromodomain. It functions as a histone acetyltransferase (HAT) to promote transcriptional activation. Acetylation of histones gives a specific tag for epigenetic transcription activation. It displays significant histone acetyltransferase activity with core histones, but not with nucleosome core particles. KAT2A is also shown to acetylate non-histone proteins, such as CCAAT/enhancer-binding protein beta (CEBPB). In case of HIV-1 infection, histone acetyltransferase KAT2A is recruited by the viral protein Tat and it can regulates Tat′s transactivating activity and may help in inducing chromatin remodeling of proviral genes. Two isoforms of histone acetyltransferase KAT2A have been reported that are produced by alternative splicing. Isoform 2 lacks the first 410 amino acids.
~94 kDa observed; 93.93 kDa calculated. Uncharacterized bands may be observed in some lysate(s).
