Research Backgrounds

Function:

Protein lysine acyltransferase that can act as a acetyltransferase, glutaryltransferase or succinyltransferase, 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. 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, 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. 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.

Subcellular Location:

Nucleus. Chromosome. Cytoplasm>Cytoskeleton>Microtubule organizing center>Centrosome.
Note: Mainly localizes to the nucleus (PubMed:27796307). Also localizes to centrosomes in late G1 and around the G1/S transition, coinciding with the onset of centriole formation (PubMed:27796307).

Component of the STAGA transcription coactivator-HAT complex, at least composed of SUPT3H, KAT2A, SUPT7L, TAF5L, TAF6L, TADA3L, TAD1L, TAF10, TAF12, TRRAP and TAF9. The STAGA core complex is associated with a subcomplex required for histone deubiquitination composed of ATXN7L3, ENY2 and USP22. Component of the ADA2A-containing complex (ATAC), composed of KAT14, KAT2A, TADA2L, TADA3L, ZZ3, MBIP, WDR5, YEATS2, CCDC101 and DR1. In the complex, it probably interacts directly with KAT14, MBIP and WDR5. Interacts with PML (By similarity). Interacts with CEBPB. Interacts with TACC1, TACC2 and TACC3. Interacts with RELA (By similarity). Interacts with NFATC2 (By similarity). Interacts with TBX5. Interacts with PLK4. Associates with the 2-oxoglutarate dehydrogenase complex. Interacts with XPC; leading to KAT2A recruitment to promoters and subsequent acetylation of histones. Interacts with ERCC3/XPB; leading to KAT2A recruitment to promoters and subsequent acetylation of histones.

(Microbial infection) Interacts with and acetylates HIV-1 Tat.

Family&Domains:

Loop3 is required for substrate specificity and adopts different structural conformations in succinyl-CoA-bound and acetyl-CoA-bound forms. Tyr-645 has an important role in the selective binding of succinyl-CoA over acetyl-CoA.

Belongs to the acetyltransferase family. GCN5 subfamily.
