ProteomicsIsoleucyl-tRNA synthetase interactome
Aminoacyl-tRNA synthetases are key enzymes in protein synthesis, as they catalyze the attachment of amino acids to their designated, cognate tRNAs. As such, mutations in aminoacyl-tRNA synthetases are associated with severe diseases, such as neurodevelopmental disorders. Many of these mutations fall...

ProteomicsSRRM2 wt and SRRM2 S1444P interactome
Multisystem proteinopathy (MSP) is a pleiotropic degenerative disorder which affects the nervous system, muscles, and bones. The identification of risk factors and their molecular contribution to MSP expands our understanding of disease mechanisms. Here, we describe a family with dominantly inherite...

ProteomicsCharacterizing the interactome of human Arginyl-tRNA Synthethase
Prior work revealed nuclear-localized aminoacyl-tRNA synthetases (aaRSs) that checked newly synthesized tRNAs for charging before export to the cytoplasm. To reveal other functions, we sought to identify nuclear proteins that interact with arginyl-tRNA synthetase (ArgRS) in the nucleus. Serine/Arg...

ProteomicsMethionyl-tRNA synthetase interactome
During mRNA translation, tRNAs are charged by aminoacyl-tRNA synthetases (aaRS) and subsequently used by ribosomes. A multi-enzyme aminoacyl-tRNA synthetase complex (MSC) has long been proposed to increase protein synthesis efficiency by passing charged tRNAs directly to ribosomes. An alternative is...

ProteomicsMHCI peptidome of HepG2 with ArgRS or SRRM2 knock down
Cells respond to perturbations like inflammation by sensing changes in metabolite levels. Especially prominent is arginine, which has known connections to the inflammatory response. Here, we found that depletion of arginine during inflammation decreased levels of a nuclear form of arginyl-tRNA synth...

ProteomicsN-terminomics upon Arginyl-tRNA synthetase knock down
Arginine is associated with inflammation, cancer, and amino acid signaling, in part through the mTORC1 pathway. In cell-based assays and in the mouse, we found that arginine regulates nuclear levels of arginyl-tRNA synthetase (ArgRS), and that arginine depletion and inflammation reduced nuclear ArgR...
