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 A16; this heterodimer further interact with A56/K2
CC       fusion regulatory heterodimer (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000250}; Single-pass type
CC       II membrane protein {ECO:0000305}. Note=Component of the mature virion
CC       (MV) membrane. The mature virion is located in the cytoplasm of
CC       infected cells and is probably released by cell lysis (By similarity).
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the poxviridae A16/G9/J5 family. {ECO:0000305}.
