Extended PHD finger found in bromodomain and PHD finger-containing protein 3 (BRPF3) and similar proteins
The extended plant homeodomain (ePHD) zinc finger is characterized as Cys2HisCys5HisCys2His. This model includes the ePHD finger of BRPF3. BRF3 is a homolog of BRPF1 and BRPF2. It is a scaffold protein that forms a novel monocytic leukemic zinc finger protein (MOZ)/MOZ-related factor (MORF) H3 histone acetyltransferase (HAT) complex with other regulatory subunits. BRPF3 contains a plant homeodomain (PHD) finger followed by this non-canonical ePHD finger, a bromodomain, and a proline-tryptophan-tryptophan-proline (PWWP) domain.

Evidence:
Comment:based on the structure evidence that human Borjeson-Forssman-Lehmann syndrome-associated protein PHF6 (PDB 4NN2) binds three Zn2+ ions through its ePHD finger
Comment:The extended PHD finger is characterized by Cys2HisCys5HisCys2His.
