What's a GeneRIF?

study suggests that the structure and function of Arc1p can be modulated via biotinylation in response to temperature changes.
Title: Modulating the Structure and Function of an Aminoacyl-tRNA Synthetase Cofactor by Biotinylation.
An ab initio model of both trimeric and the pentameric complexes containing Arc1,GluRS and MetRS.
Title: Quaternary structure of the yeast Arc1p-aminoacyl-tRNA synthetase complex in solution and its compaction upon binding of tRNAs.
dual localization of (c)ERS is controlled by binding to Arc1p
Title: Yeast mitochondrial Gln-tRNA(Gln) is generated by a GatFAB-mediated transamidation pathway involving Arc1p-controlled subcellular sorting of cytosolic GluRS.
assembly of the Arc1p-synthetase complex is mediated exclusively by the N-terminal domains of the synthetases and that the two enzymes bind to largely independent sites on Arc1p.
Title: Molecular determinants of the yeast Arc1p-aminoacyl-tRNA synthetase complex assembly.
These results are consistent with a model according to which Arc1p is a bifunctional protein involved in the subcellular localization of ScMetRS and ScGluRS via its N-terminal domain and of tRNA via its C-terminal domain.
Title: Arc1p is required for cytoplasmic confinement of synthetases and tRNA.
Present study suggests a more complex picture for Arc1p-mediated stimulation of yeast tRNA glutamylation than just a role in increasing the glutamyl-tRNA synthetase binding affinity for tRNAGlu.
Title: Role of Arc1p in the modulation of yeast glutamyl-tRNA synthetase activity.
The structure of the interacting domain of yeast glutamyl-tRNA synthetase (GluRS) and its accessory protein Arc1p was determined and refined to 1.9 A resolution.
Title: Structures of the interacting domains from yeast glutamyl-tRNA synthetase and tRNA-aminoacylation and nuclear-export cofactor Arc1p reveal a novel function for an old fold.
cytoplasmic location of Arc1p is maintained by Xpo1p-dependent nuclear export
Title: The tRNA aminoacylation co-factor Arc1p is excluded from the nucleus by an Xpo1p-dependent mechanism.
