Bifunctional aminoacyl-tRNA synthetase is an enzyme that in humans is encoded by the EPRS gene. [5] [6]

Gene

Alternative splicing has been observed for this gene, but the full-length nature and biological validity of the variant have not been determined. [6]

Function

Aminoacyl-tRNA synthetases are a class of enzymes that charge tRNAs with their cognate amino acids. The protein encoded by this gene is a multifunctional aminoacyl-tRNA synthetase that catalyzes the aminoacylation of glutamic acid and proline tRNA species. [6]

Phosphorylation of EPRS is reported to be essential for the formation of GAIT (Gamma-interferon Activated Inhibitor of Translation) complex that regulates the translation of multiple genes in monocytes and macrophages. [7]

Interactions

EPRS has been shown to interact with POU2F1, [8] Heat shock protein 90kDa alpha (cytosolic), member A1 [9] and IARS. [10]

In molecular biology, the protein domain WHEP-TRS refers to helix-turn-helix domains. They are found in variable numbers in glutamyl-prolyl tRNA synthetase (EPRS). This protein domain has an important function in protein–protein interactions between synthetases. WHEP domains exhibit high-affinity interactions with tRNA, indicating a putative evolutionary relationship to facilitate tRNA binding to fused synthetases, thereby enhancing catalytic efficiency.

Karin Musier-Forsyth, an American biochemist, is an Ohio Eminent Scholar on the faculty of the Department of Chemistry & Biochemistry at Ohio State University. Musier-Forsyth's research involves biochemical, biophysical and cell-based approaches to understand the interactions of proteins and RNAs involved in protein synthesis and viral replication, especially in HIV.

Xiang-Lei Yang (杨湘磊) is a Chinese-born American molecular biologist. She is a professor at The Scripps Research Institute, located in La Jolla, California. Her work has contributed to the establishment of physiological importance of aminoacyl-tRNA synthetases beyond their classical role in supporting mRNA translation and their disordered processes that contribute to disease. She founded the Translation Machinery in Health and Disease Gordon Research Conference, an ongoing biannual international conference since 2015. She helped co-found aTyr Pharma, a Nasdaq-listed biotechnology company.
