Protein: Histone acetyltransferase GCN5 (AtGCN5) (EC 2.3.1.48) (BIG TOP protein) (Q9AR19)
Organism: Arabidopsis thaliana (Mouse-ear cress)
Function: Acetylates histone H3 and ADA2 proteins in vitro. Acetylates 'Lys-14' of histone H3. Acetylation of histones gives a specific tag for epigenetic transcription activation. Operates in concert with certain DNA-binding transcriptional activators. Acts via the formation of large multiprotein complexes that modify the chromatin (By similarity).
Subcellular location: Nucleus {ECO:0000305}.
