Is predicted to encode a protein with the following domains: WSTF, HB1, Itc1p, MBD9 motif 1; Bromodomain; WHIM2 domain; Zinc finger, PHD-type; Williams-Beuren syndrome DDT (WSD), D-TOX E motif; Zinc finger, RING/FYVE/PHD-type; ATP-utilising chromatin assembly and remodelling N-terminal; WSTF/Acf1/Cbp146; WHIM1 domain; Bromodomain-like superfamily; DDT domain; and Zinc finger, FYVE/PHD-type. Is an ortholog of C. elegans athp-2.
