CC -!- FUNCTION: Envelope protein part of the entry-fusion complex responsible
CC for the virus membrane fusion with host cell membrane during virus
CC entry. Also plays a role in cell-cell fusion (syncytium formation) (By
CC similarity). {ECO:0000250}.
CC -!- SUBUNIT: Part of a stable entry-fusion complex (EFC) which is at least
CC composed of proteins A16, A21, A28, G3, G9, H2, J5, and L5. Formation
CC of the viral membrane is necessary for the assembly of the complex.
CC Interacts with G3 (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000250}; Single-pass type
CC III membrane protein {ECO:0000305}. Note=Component of the mature virion
CC (MV) membrane (By similarity). The mature virion is located in the
CC cytoplasm of infected cells and is probably released by cell lysis.
CC {ECO:0000250}.
CC -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC -!- PTM: Most cysteines are linked by disulfide bonds. They are created by
CC the viral disulfide bond formation pathway, a poxvirus-specific redox
CC pathway that operates on the cytoplasmic side of the MV membranes (By
CC similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the chordopoxvirinae L5 family. {ECO:0000305}.
