Has histone acetyltransferase activity in vitro, with specificity for histone H4. acetyl-CoA + L-lysyl-[protein] = CoA + H(+) + N(6)-acetyl-L-lysyl-[protein] C-terminally tagged constructs localize to the nuclear membrane and perinuclear region. N-terminally tagged constructs show a punctate cytoplasmic distribution. Belongs to the camello family.
