Is predicted to encode a protein with the following domains: PHD-finger; Zinc finger, PHD-finger; Zinc finger protein neuro-d4; Zinc finger, FYVE/PHD-type; Zinc finger, RING/FYVE/PHD-type; and Zinc finger, PHD-type. Is an ortholog of C. elegans dpff-1. In C. elegans, dpff-1 is involved in apoptotic process; meiotic cell cycle; and response to heat.
