CC   -!- FUNCTION: Envelope protein required for virus entry into host cell and
CC       for cell-cell fusion (syncytium formation). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000305}; Single-pass type
CC       II membrane protein {ECO:0000305}. Note=Component of the intracellular
CC       mature virion (IMV) membrane. {ECO:0000250}.
CC   -!- PTM: Contains two intramolecular disulfide bonds. They are created by
CC       the viral disulfide bond formation pathway, a poxvirus-specific pathway
CC       that operates on the cytoplasmic side of the MV membranes (By
CC       similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the poxviridae A28 protein family.
CC       {ECO:0000305}.
