[https://www.uniprot.org/uniprot/ARC1_YEAST ARC1_YEAST] Binds to tRNA and functions as a cofactor for the methionyl-tRNA synthetase (MetRS) and glutamyl-tRNA synthetase (GluRS). Forms a complex with MetRS and GluRS and increases their affinity for cognate tRNAs due to the presence of a tRNA binding domain in its middle and C-terminal part. Binds specifically G4 quadruplex nucleic acid structures (these are four-stranded right-handed helices, stabilized by guanine base quartets). Also required for cytoplasmic confinement of the synthetases and tRNA.<ref>PMID:11069915</ref> <ref>PMID:17131041</ref> <ref>PMID:8895587</ref> <ref>PMID:9659920</ref>
