Protein lysine acyltransferase that can act both as a acetyltransferase and succinyltransferase, depending on the context (By similarity). Acts as a histone lysine succinyltransferase: catalyzes succinylation of histone H3 on 'Lys-79' (H3K79succ), with a maximum frequency around the transcription start sites of genes (By similarity). Succinylation of histones gives a specific tag for epigenetic transcription activation (By similarity). Association with the 2-oxoglutarate dehydrogenase complex, which provides succinyl-CoA, is required for histone succinylation (By similarity). In different complexes, functions either as an acetyltransferase (HAT) or as a succinyltransferase: in the SAGA and ATAC complexes, acts as a histone acetyltransferase (By similarity). Has significant histone acetyltransferase activity with core histones, but not with nucleosome core particles (By similarity). Acetylation of histones gives a specific tag for epigenetic transcription activation (By similarity). Also acetylates non-histone proteins, such as tbx5 (PubMed:29174768). Involved in heart and limb development by mediating acetylation of tbx5 (PubMed:29174768).

Belongs to the acetyltransferase family. GCN5 subfamily.
