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}.
