What's a GeneRIF?

Gle1 is required for tRNA to stimulate Dbp5 ATPase activity in vitro and promote Dbp5-mediated tRNA export in vivo in Saccharomyces cerevisiae.
Title: Gle1 is required for tRNA to stimulate Dbp5 ATPase activity in vitro and promote Dbp5-mediated tRNA export in vivo in Saccharomyces cerevisiae.
The nucleoporin Gle1 activates DEAD-box protein 5 (Dbp5) by promoting ATP binding and accelerating rate limiting phosphate release.
Title: The nucleoporin Gle1 activates DEAD-box protein 5 (Dbp5) by promoting ATP binding and accelerating rate limiting phosphate release.
Gle1 is a multifunctional DEAD-box protein regulator that modulates Ded1 in translation initiation.
Title: Gle1 is a multifunctional DEAD-box protein regulator that modulates Ded1 in translation initiation.
Gle1 specifically binds IP(6); this interaction is required for the full potentiation of Dbp5 ATPase activity during both mRNA export and translation termination
Title: Control of mRNA export and translation termination by inositol hexakisphosphate requires specific interaction with Gle1.
Study identified several charged surface residues that, when mutated, weaken the binding of Gle1 and inhibit the ability of Gle1 to stimulate Dbp5's ATPase activity.
Title: Structure of the C-terminus of the mRNA export factor Dbp5 reveals the interaction surface for the ATPase activator Gle1.
Study shows that Gle1 and inositol hexakisphosphate are required for efficient translation termination, in addition, Gle1 has a conserved physical association with the initiation factor eIF3.
Title: The mRNA export factor Gle1 and inositol hexakisphosphate regulate distinct stages of translation.
the Gle1-mRNA export pathway is mediated by cytoplasmic inositol hexakisphosphate production
Title: Cytoplasmic inositol hexakisphosphate production is sufficient for mediating the Gle1-mRNA export pathway.
Gle1, Nab2 and Gfd1 associate in a complex;Gfd1 serves as a bridging factor between Gle1 and Nab2-bound mRNA during export
Title: Nuclear export of the yeast mRNA-binding protein Nab2 is linked to a direct interaction with Gfd1 and to Gle1 function.
Our results define specific functions for Gle1 and InsP6 in mRNA export and suggest that local activation of Dbp5 at the nuclear pore is critical for mRNA export.
Title: Activation of the DExD/H-box protein Dbp5 by the nuclear-pore protein Gle1 and its coactivator InsP6 is required for mRNA export.
Dbp5 activation at NPCs requires Gle1 and InsP6. This would facilitate spatial control of the remodelling of mRNP protein composition during directional transport and provide energy to power transport cycles.
Title: Inositol hexakisphosphate and Gle1 activate the DEAD-box protein Dbp5 for nuclear mRNA export.
