What's a GeneRIF?

Phosphorylation controls the oligomeric state of She2 and mRNA localization in yeast.
Title: Phosphorylation controls the oligomeric state of She2 and mRNA localization in yeast.
Combining RNA- and membrane-binding features makes She2p an ideal coordinator of ER tubule and mRNA cotransport.
Title: Association of the yeast RNA-binding protein She2p with the tubular endoplasmic reticulum depends on membrane curvature.
The binding site for She3p was mapped to a single alpha helix that protrudes at right angles from She2p.
Title: Two single-headed myosin V motors bound to a tetrameric adapter protein form a processive complex.
She2p is recruited cotranscriptionally to the nascent bud-localized ASH1, IST2, and EAR1 mRNA
Title: Cotranscriptional recruitment of She2p by RNA pol II elongation factor Spt4-Spt5/DSIF promotes mRNA localization to the yeast bud.
finding on She2p tetramerization resolves previously raised questions on complex formation and mRNP function.
Title: Formation of She2p tetramers is required for mRNA binding, mRNP assembly, and localization.
She2p interacts with both Loc1p and Puf6p and excluding She2p from the nucleus decreases this interaction.
Title: Nuclear shuttling of She2p couples ASH1 mRNA localization to its translational repression by recruiting Loc1p and Puf6p.
Results indicate that the nucleolar transit of RNA-binding proteins such as She2 is necessary for the correct assembly of translationally silenced localizing messenger ribonucleoproteins.
Title: Nuclear transit of the RNA-binding protein She2 is required for translational control of localized ASH1 mRNA.
continuous transport of mRNA by Myo4p-She3p in yeast is accomplished either by multiple high duty cycle monomers or by molecules that may be dimerized by She2p, the homodimeric downstream binding partner of She3p
Title: She3p binds to the rod of yeast myosin V and prevents it from dimerizing, forming a single-headed motor complex.
anchoring of ASH1 mRNA requires molecular remodeling of the Myo4p-She3p-She2p heterotrimeric complex, a process that is apparently altered when mRNA is artificially tethered to She2p.
Title: ASH1 mRNA anchoring requires reorganization of the Myo4p-She3p-She2p transport complex.
She2p is a member of a previously unknown class of nucleic acid binding proteins, composed of a single globular domain with a five alpha helix bundle that forms a symmetric homodimer.
Title: She2p is a novel RNA binding protein with a basic helical hairpin motif.
