Poxvirus early transcription factor (VETF), large subunit
The poxvirus early transcription factor (VETF), in addition to the viral RNA polymerase, is required for efficient transcription of early genes in vitro. VETF is a heterodimeric protein that binds specifically to early gene promoters. The heterodimer is comprised of an 82 kDa (this family) subunit and a 70 kDa subunit.
