CC   -!- FUNCTION: Envelope protein which probably plays a role in virus entry
CC       into the host cell. Is probably involved in the virus attachment to the
CC       host cell surface and associates with the entry/fusion complex (EFC).
CC       Needed for fusion and penetration of the virus core into host cell (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with G4; this interaction involves formation of a
CC       transient disulfide-bonded intermediate, allowing disulfide bond
CC       transfer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000305}; Single-pass
CC       membrane protein {ECO:0000305}. Note=Localizes to the membrane
CC       surrounding the core of mature virus particles (MV). {ECO:0000250}.
CC   -!- INDUCTION: Expressed late in the viral replicative cycle.
CC   -!- PTM: Myristoylated. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the chordopoxvirinae L1 family. {ECO:0000305}.
