Abstract

RNA polymerase II molecules that transcribe the late strand of the 5.3-kb circular polyomavirus genome stall just upstream of the DNA replication origin, in a region containing multiple binding sites for polyomavirus large T antigen. Stalling of RNA polymerases depends on the presence of functional large T antigen and on the integrity of large T antigen binding site A. To gain insight into the interaction between DNA-bound large T antigen and RNA polymerase II, we mapped the position of stalled RNA polymerases by analyzing nascent RNA chains associated with these polymerases. Elongation of RNA in vitro, followed by hybridization with a nested set of DNA fragments extending progressively farther into the stalling region, allowed localization of the 3' end of the nascent RNA to a position 5 to 10 nucleotides upstream of binding site A. Ribonuclease treatment of nascent RNAs on viral transcription complexes, followed by in vitro elongation and hybridization, allowed localization of the distal end of stalled RNA polymerases to a position 40 nucleotides upstream of binding site A. This RNA footprint shows that elongating RNA polymerases stall at a site very close to the position of DNA-bound large T antigen and that they protect approximately 30 nucleotides of nascent RNA against ribonuclease digestion.
