The carboxyl-terminal repeat domain of RNA polymerase II is not required for transcription factor Sp1 to function in vitro.

Journal Article

We show that the mammalian transcription Sp1 stimulates accurate transcription in a partially fractionated RNA polymerase II-dependent system from Drosophila cultured cells. Moreover, the extent of stimulation is equal for intact RNA polymerase II (polymerase IIA) and polymerase lacking the unique carboxyl-terminal domain of the largest subunit (polymerase IIB). We conclude that in this system Sp1 interacts with a component of the transcription machinery, other than the carboxyl-terminal domain, which is preserved between mammals and insects.
