Protein lysine acyltransferase that can act as a acetyltransferase, glutaryltransferase, succinyltransferase or malonyltransferase, depending on the context . 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 . Succinylation of histones gives a specific tag for epigenetic transcription activation . Association with the 2-oxoglutarate dehydrogenase complex, which provides succinyl-CoA, is required for histone succinylation . In different complexes, functions either as an acetyltransferase (HAT) or as a succinyltransferase: in the SAGA and ATAC complexes, acts as a histone acetyltransferase . Has significant histone acetyltransferase activity with core histones, but not with nucleosome core particles . Has a a strong preference for acetylation of H3 at ''Lys-9'' (H3K9ac) . Acetylation of histones gives a specific tag for epigenetic transcription activation . Recruited by the XPC complex at promoters, where it specifically mediates acetylation of histone variant H2A.Z.1/H2A.Z, thereby promoting expression of target genes . Involved in long-term memory consolidation and synaptic plasticity: acts by promoting expression of a hippocampal gene expression network linked to neuroactive receptor signaling (By similarity). Acts as a positive regulator of T-cell activation: upon TCR stimulation, recruited to the IL2 promoter following interaction with NFATC2 and catalyzes acetylation of histone H3 at ''Lys-9'' (H3K9ac), leading to promote IL2 expression (By similarity). Required for growth and differentiation of craniofacial cartilage and bone by regulating acetylation of histone H3 at ''Lys-9'' (H3K9ac) (By similarity). Regulates embryonic stem cell (ESC) pluripotency and differentiation (By similarity). Also acetylates non-histone proteins, such as CEBPB, MRE11, PPARGC1A, PLK4 and TBX5 . Involved in heart and limb development by mediating acetylation of TBX5, acetylation regulating nucleocytoplasmic shuttling of TBX5 . Acts as a negative regulator of centrosome amplification by mediating acetylation of PLK4 . Acts as a negative regulator of gluconeogenesis by mediating acetylation and subsequent inactivation of PPARGC1A . Also acts as a histone glutaryltransferase: catalyzes glutarylation of histone H4 on ''Lys-91'' (H4K91glu), a mark that destabilizes nucleosomes by promoting dissociation of the H2A-H2B dimers from nucleosomes . .; (Microbial infection) 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. .
