| description | The ePHD ("extended plant homeodomain") zinc finger is characterized as Cys2HisCys5HisCys2His. This entry represents the ePHD finger of Jade-2. Jade-2 is a homeodomain (PHD) zinc finger protein that is closely related to Jade-1, which functions as an essential regulator of multiple cell signaling pathways. Like Jade-1, Jade-2 is required for ING4 and ING5 to associate with histone acetyltransferase (HAT) HBO1 and Eaf6 to form a HBO1 complex that has a histone H4-specific acetyltransferase activity, a reduced activity toward histone H3, and is responsible for the bulk of histone H4 acetylation in vivo. Jade-2 contains a canonical PHD finger followed by this non-canonical ePHD finger, both of which are zinc-binding motifs [, ]. |
