RNA polymerase I Promoter Clearance is complete and Chain Elongation begins (Milkereit and Tschochner, 1998).
The assembly of the initiation complex on the promoter and the transition from a closed to an open complex is then followed by promoter clearance and transcription elongation by RNA Pol I. Unlike the RNA polymerase II system, RNA polymerase I transcription does not require a form of energy such as ATP for initiation and elongation. Regulatory mechanisms operating at both the level of transcription initiation and elongation probably concurrently to adjust the level of rRNA synthesis to the need of the cell.9649439Pubmed1998A specialized form of RNA polymerase I, essential for initiation and growth-dependent regulation of rRNA synthesis, is disrupted during transcriptionMilkereit, PTschochner, HEMBO J. 17:3692-70311032814Pubmed2000The recruitment of RNA polymerase I on rDNA is mediated by the interaction of the A43 subunit with Rrn3Peyroche, GMilkereit, PBischler, NTschochner, HSchultz, PSentenac, ACarles, CRiva, MEMBO J. 19:5473-82inferred by electronic annotationIEAGOIEAReactome Database ID Release 7510696851Database identifier.
