What's a GeneRIF?

Identification of specific residues required to support Grc3-directed Las1-mediated pre-rRNA cleavage.
Title: Characterization of the molecular crosstalk within the essential Grc3/Las1 pre-rRNA processing complex.
Grc3 drives Las1 endoribonuclease cleavage to its targeted C2 site both in vitro and in Saccharomyces cerevisiae. The tetrameric Grc3/Las1 complex is a unique example of a protein-guided programmable endoribonuclease.
Title: Grc3 programs the essential endoribonuclease Las1 for specific RNA cleavage.
Authors propose that Las1 and Grc3 function together in a conserved mechanism to modulate rRNA processing and eukaryotic ribosome biogenesis.
Title: Las1 interacts with Grc3 polynucleotide kinase and is required for ribosome synthesis in Saccharomyces cerevisiae.
Grc3 is a polynucleotide kinase; inactivation reduces the efficiency of termination by Pol I.
Title: Role of the RNA/DNA kinase Grc3 in transcription termination by RNA polymerase I.
