Promotes the release of progeny virus from the host cell nucleus by accelerating the lysis and death of the host cell. May interact with host MAD2L2/MAD2B. Initially associates with the endoplasmic reticulum and Golgi apparatus and ultimately localizes to the nuclear membrane. Glycosylated by host. Palmitoylated at cytoplasmic tail. Belongs to the adenoviridae ADP family.
