TFIIS enhancement of Pol II cleavage is under kinetic control
Abstract The eukaryotic RNA polymerases (Pols) contain subunits or interact with trans-acting factors that confer robust endonuclease activity. A12.2 and C11 are subunits of Pol I and Pol III, respectively. Pol II, however, recruits transcription factor IIS (TFIIS). This evolutionary divergence of A12.2 and C11 being b...
