CC   -!- FUNCTION: Late DNA-binding protein which binds to the hairpin form of
CC       the viral telomeric sequence. Required for the production of mature
CC       virions (MV) (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000250}. Note=Present in the virus
CC       core. {ECO:0000250}.
CC   -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC   -!- MISCELLANEOUS: Each virion contains approximately 670 molecules of I1.
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the chordopoxvirinae I1 family. {ECO:0000305}.
