CC   -!- FUNCTION: DNA-directed RNA polymerase-associated factor required for
CC       the transcription of viral early genes as well as for transcription
CC       termination. Within minutes after virus entry, recruits the core RNA
CC       polymerase, the early transcription factor (ETF) and other enzymes
CC       needed for transcription initiation, elongation, and termination
CC       thereby allowing synthesis of early mRNAs which are extruded through
CC       pores in the core particle. Recruits the multifunctional J3 protein,
CC       with poly(A) polymerase-stimulatory, cap nucleoside-2'-O-
CC       methyltransferase, and transcription elongation activities. Interacts
CC       with NPH-I, a DNA-dependent ATPase required for the termination of
CC       early transcripts. Acts as a transcription termination factor by
CC       binding, together with the capping enzyme/VTF, to the termination motif
CC       5'-UUUUUNU-3' in the nascent mRNA. Involved as well in the packaging of
CC       RNA polymerase and other components needed for early transcription in
CC       assembling virus particles (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Part of the early transcription complex composed of ETF,
CC       RAP94, and the DNA-directed RNA polymerase. Interacts (via N-terminus)
CC       with NPH-I. Interacts with J3. Interacts with ETF heterodimer (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion {ECO:0000305}. Note=All the enzymes and
CC       other proteins required to synthesize early mRNAs are packaged within
CC       the virion core along with the DNA genome. {ECO:0000250}.
CC   -!- INDUCTION: Expressed in the late phase of the viral replicative cycle.
CC   -!- DOMAIN: Interacts with ETF via its N-terminus and with DNA-directed RNA
CC       polymerase via its C-terminus. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the poxviridae protein RAP94 family.
CC       {ECO:0000305}.
