This domain catalyses the acetylation of lysine residues on histone H3, including H3K56, H3K9, H3K14, H3K23 and H3K27 [1,2]. The domain functions within a complex with histone chaperones such as VPS75 that regulate substrate specificity [3]. Acetylation of H3K56 by this domain promotes nucleosome assembly, DNA repair and transcriptional regulation during S-phase [1,2]. The domain is also found in other histone acetyltransferases including p300/CBP which share a similar fold but differ in catalytic properties and cofactor requirements [3]. Members of this family show conservation across most eukaryotic fungi.
