EPRS-like_RNA binding domain. This short RNA-binding domain is found in several higher eukaryote aminoacyl-tRNA synthetases (aaRSs). It is found in three copies in the mammalian bifunctional EPRS in a region that separates the N-terminal GluRS from the C-terminal ProRS. In the Drosophila EPRS, this domain is repeated six times. It is found at the N-terminus of TrpRS, HisRS and GlyR and at the C-terminus of MetRS. This domain consists of a helix- turn- helix structure, which is similar to other RNA-binding proteins. It is involved in both protein-RNA interactions by binding tRNA and protein-protein interactions, which are important for the formation of aaRSs into multienzyme complexes.
