General annotation (Comments)

Function	Catalytic histone acetyltransferase subunit of the RNA polymerase II elongator complex, which is a component of the RNA polymerase II (Pol II) holoenzyme and is involved in transcriptional elongation. Elongator may play a role in chromatin remodeling. May also have a methyltransferase activity By similarity.
Catalytic activity	Acetyl-CoA + histone = CoA + acetylhistone.
Cofactor	Binds 1 4Fe-4S cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L-methionine By similarity.
Subunit structure	Component of the RNA polymerase II elongator complex (Elongator). Elongator associates with the C-terminal domain (CTD) of Pol II largest subunit By similarity.
Subcellular location	Nucleus By similarity.
Sequence similarities	Belongs to the ELP3 family. Contains 1 N-acetyltransferase domain.
