What's a GeneRIF?

These analyses identified an essential region of Bdp1 that is positioned within the active site cleft of Pol III and necessary for transcription initiation.
Title: A Region of Bdp1 Necessary for Transcription Initiation That Is Located within the RNA Polymerase III Active Site Cleft.
A structural model of the interaction interface between Bdp1 (RNA poplymerase III essential subunit) and Brf1 (TFIIIB B-related factor) shows the main Bdp1 anchorage site provided by a small set of residues belonging to a Brf1 segment of residues 470-495.
Title: Structural characterization of the interaction between TFIIIB components Bdp1 and Brf1.
Entry of Brf1 and Bdp1 into the transcription complex imposes a strict sequence preference for the downstream half of the TATA box that matches the TATA box of the pol III-transcribed U6 small nuclear RNA gene.
Title: The Saccharomyces cerevisiae RNA polymerase III recruitment factor subunits Brf1 and Bdp1 impose a strict sequence preference for the downstream half of the TATA box.
Bdp1p is required for periodic integration of the Ty1 retrotransposon and targeting of Isw2p to tDNAs.
