What's a GeneRIF?

RNA polymerase I (Pol I) lobe-binding subunit Rpa12.2 promotes RNA cleavage and proofreading.
Title: RNA polymerase I (Pol I) lobe-binding subunit Rpa12.2 promotes RNA cleavage and proofreading.
Study demonstrate that Rpa12p interacts with the transcription factor Msn4p and prevents its binding to the promoter of AYR1, a key enzyme involved in triacylglycerol biosynthesis and mobilization of nonpolar lipids. These results suggest that the deletion of RPA12 derepresses Msn4p, thus activating the transcription of AYR1, which leads to the accumulation of triacylglycerol in the rpa12D mutant.
Title: The RNA polymerase I subunit Rpa12p interacts with the stress-responsive transcription factor Msn4p to regulate lipid metabolism in budding yeast.
