What's a GeneRIF?

Data suggest that the RNA polymerase I (Pol I) I transcription initiation cycle allows comparisons with promoter opening by Pol II and Pol III.
Title: Molecular insight into RNA polymerase I promoter recognition and promoter melting.
These results indicate that Rpa49, Rrn3 and Mot1 directly or indirectly influence biogenesis
Title: Identification of factors that promote biogenesis of tRNA(CGA)(Ser).
Core Factor's intrinsic mobility correlates well with different conformational states of the Pol I cleft, in addition to the stabilization of either Rrn7 N-terminal domain near Pol I wall or the tandem winged helix domain of A49 at a partially overlapping location.
Title: Structural mechanism of ATP-independent transcription initiation by RNA polymerase I.
yeast A34.5/A49 and mammalian PAF49/PAF53 heterodimeric complexes interact through species-specific sequence elements that appear to assume similar structural motifs.
Title: Characterization of the interactions of mammalian RNA polymerase I associated proteins PAF53 and PAF49.
