Interacts with host ITCH; this interaction probably mediates ITCH degradation. Late-budding domains (L domains) are short sequence motifs essential for viral particle budding. They recruit proteins of the host ESCRT machinery (Endosomal Sorting Complex Required for Transport) or ESCRT-associated proteins. Contains one L domain: a PPXY motif which is involved in the interaction with ITCH, a member of the NEDD4 family. Belongs to the varicellovirus ORF0 protein family.
