CC   -!- FUNCTION: Late protein which probably plays a role in virus entry into
CC       the host cell. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000305}; Single-pass
CC       membrane protein {ECO:0000305}. Note=Component of the membrane of the
CC       mature virion.
CC   -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC   -!- SIMILARITY: Belongs to the chordopoxvirinae I2 family. {ECO:0000305}.
