CC   -!- FUNCTION: Facilitates virus attachment to oral epithelial cells by
CC       binding to host beta1 integrin family. Participates in rearrangement of
CC       cellular actin to increase intercellular contacts by binding BDLF2 and
CC       thereby promote virus cell-to-cell spreading (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with BDLF2. Interacts with host beta1 integrin
CC       family (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion membrane; Multi-pass membrane protein.
CC       Host cell membrane. Note=In EBV-infected polarized oral epithelial
CC       cells, is transported to the basolateral membranes and colocalizes with
CC       beta1 integrin. {ECO:0000250}.
CC   -!- DOMAIN: The RGD motif presumably is the main binding site to host beta1
CC       integrins. {ECO:0000250}.
CC   -!- PTM: Extensively glycosylated by O-linked oligosaccharides.
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the herpesviridae BMRF2 family. {ECO:0000305}.
