CC -!- FUNCTION: Acts with RNA polymerase to initiate transcription from early
CC gene promoters. Is recruited by the RPO-associated protein of 94 kDa
CC (RAP94) to form the early transcription complex, which also contains
CC the core RNA polymerase. ETF heterodimer binds to early gene promoters
CC (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Heterodimer of a 70 kDa and a 82 kDa subunit. Part of the
CC early transcription complex composed of ETF, RAP94, and the DNA-
CC directed RNA polymerase (By 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. This is necessary because
CC viral early mRNAs are synthesized within minutes after virus entry into
CC the cell and are extruded through pores in the core particle.
CC -!- SIMILARITY: Belongs to the helicase family. VETF subfamily.
CC {ECO:0000305}.
