What's a GeneRIF?

analysis establishes the structural foundation for the recognition of aberrantly stalled 80S ribosomes by the Dom34.Hbs1.GTP complex during Dom34-mediated mRNA surveillance pathways
Title: Structural insights into ribosomal rescue by Dom34 and Hbs1 at near-atomic resolution.
Translational effects of Dom34 required the 5'-UTR of the PMT1 transcript, which bound recombinant Dom34 directly at a CA/AC-rich sequence and regulated in vitro translation. Polysomal profiling revealed that Dom34 stimulates general translation moderately, but that it is especially required for translation of transcripts encoding Pmt isoforms 1, 4 and 6.
Title: Dom34 Links Translation to Protein O-mannosylation.
Study found that Dom34 rescues ribosomes that stall at the 3' end of mRNAs that are truncated. Dom34 rescues ribosomes in the 3' untranslated region of many genes. Surprisingly, many ribosomes populate this noncoding region, and these ribosomes seem to move along the mRNA without recognizing codons, presumably not translating, and eventually arrest.

Roles of dom34:hbs1 in nonstop protein clearance from translocators for normal organelle protein influx.
Title: Roles of dom34:hbs1 in nonstop protein clearance from translocators for normal organelle protein influx.
Dom34:Hbs1 facilitates the decay of nonstop mRNAs from the 3' end by exosomes and is required for the complete degradation of nonstop mRNA decay intermediates.
Title: Dom34:hbs1 plays a general role in quality-control systems by dissociation of a stalled ribosome at the 3' end of aberrant mRNA.
The close structural similarity of Dom34 and Hbs1 to eukaryotic release factors (eRFs) enabled the authors to propose a model for the ribosome-bound eRF1-eRF3 complex.
Title: Structure of the no-go mRNA decay complex Dom34-Hbs1 bound to a stalled 80S ribosome.
The slow growth of cells lacking Dom34 and haploinsufficient for a protein of the 40S subunit is caused by a severe shortage of 40S subunits available for translation initiation.
Title: Why Dom34 stimulates growth of cells with defects of 40S ribosomal subunit biosynthesis.
findings show that Dom34:Hbs1 (two interacting factors genetically implicated in no-go decay) interacts with the ribosome to promote subunit dissociation and peptidyl-tRNA drop-off
Title: Dom34:Hbs1 promotes subunit dissociation and peptidyl-tRNA drop-off to initiate no-go decay.
Results identify important functional regions of Dom34 and suggest that the proposed endonuclease activity of Dom34 is not required for mRNA cleavage in NGD.
Title: Analysis of Dom34 and its function in no-go decay.
Dom34 has a role in an mRNA decay pathway called No-Go decay and the interaction of Dom34 with Hbs1 results in an increase in the affinity constant of Hbs1 for GTP but not GDP
