aTyr Pharma to Present Poster Highlighting Research Approach for Identifying Receptor Targets for Extracellular tRNA Synthetases
Poster to be presented at the 2021
Research approach led to the identification of target receptors for two tRNA synthetases and further validates company’s biology platform.
The poster describes a mass spectrometry proteomics-based approach to identify target receptors for two distinct extracellular tRNA synthetase fragments. The utilization of this workflow, which included recombinant protein expression, flow cytometry, and receptor screening in living cells using the ligand-receptor capture TriCEPS technology, resulted in the identification of receptor targets for fragments of the tRNA synthetases AARS and DARS as well as insights into their potential biological activity in immunology, cancer and fibrosis. Furthermore, this approach can be applied more broadly to identify receptor targets of extracellular proteins and other ligands such as peptides, antibodies or viruses.
Details of the abstract and poster presentation are as follows:
Title: A mass spectrometry proteomics-based approach to identify target receptors for novel extracellular tRNA synthetase fragments
The poster is also available on the aTyr website.
“We are pleased to present our findings utilizing a novel approach for identifying receptor targets of extracellular proteins, and for the first time provide insight into the potential biological function of extracellular tRNA synthetases AARS and DARS,” said
aTyr is a biotherapeutics company engaged in the discovery and development of innovative medicines based on novel biological pathways. aTyr’s research and development efforts are concentrated on a newly discovered area of biology, the extracellular functionality and signaling pathways of tRNA synthetases. aTyr has built a global intellectual property estate directed to a potential pipeline of protein compositions derived from 20 tRNA synthetase genes and their extracellular targets. aTyr’s primary focus is ATYR1923, a clinical-stage product candidate which binds to the neuropilin-2 receptor and is designed to down-regulate immune engagement in inflammatory lung diseases.
