PTRF Binds the Polymerase I Transcription Complex/Nascent Pre rRNA Complex paused at the TTF-I:Sal Box (R-HSA-74993)

Species Homo sapiens

Summation

Dissociation of paused ternary complexes requires the Polymerase I-transcript release factor (PTRF) a leucine zipper protein. PTRF is capable of dissociating ternary Pol I transcription complexes, interacting with both TTF-I and Pol I to mediate the release of both Pol I and nascent transcripts from the template.
