PTRF
Polymerase I and transcript release factor, also known as PTRF, is a protein which in humans is encoded by the ''PTRF'' gene.〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=284119 )〕 ==Function== Termination of RNA polymerase I catalyzed transcription is a 2-step process that involves pausing of transcription elongation and release of both the pre-ribosomal RNA and Pol I from the DNA template. The pausing is mediated by TTF1 and PTRF. PTRF is a soluble protein containing putative leucine zipper, nuclear localization signal, and PEST domains.
