This complex is thought to interact with the nascent RNA strand during RNA polymerase II elongation[1]. This family includes the homologs from RNA polymerase I and III. In RNA polymerase I, Rpa43 is at leas ...Rpb7 bind to Rpb4 to form a heterodimer. This complex is thought to interact with the nascent RNA strand during RNA polymerase II elongation[1]. This family includes the homologs from RNA polymerase I and III. In RNA polymerase I, Rpa43 is at least one of the subunits contacted by the transcription factor TIF-IA [2]. The N terminus of Rpb7p/Rpc25p/MJ0397 has a SHS2 domain that is involved in protein-protein interaction [3].
Domain
