UniProtKB description: 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.
