Plays a role in the sorting of ODV envelope proteins to the host inner nuclear membrane. May facilitate the fusion and release of nucleocapsids into the cytoplasm. Modulates the expression levels of IE0 and IE1. Interacts with proteins IE0 and IE1. Interacts with protein FP25K. Interacts with host importin alpha-16. Early in infection, localizes both in the host nucleus and cytoplasm while later in infection localizes in viral-induced microvesicles within the host nucleus. Palmitoylated.
