aTyr Pharma Announces LTBP1 as Target of DARS tRNA Synthetase Fragment
aTyr Pharma, Inc. (Nasdaq: LIFE) has announced the identification of LTBP1 as a target through its tRNA synthetase platform in collaboration with Dualsystems Biotech AG. LTBP1 serves as a key regulator of transforming growth factor beta (TGF-β), involved in fibrotic diseases. The company plans to present further findings related to LTBP1 at an upcoming scientific conference. This discovery is aimed at advancing the development of new therapeutic candidates targeting immune regulation and fibrosis.
- Identification of LTBP1 as a key target for fibrotic diseases enhances drug discovery efforts.
- Collaboration with Dualsystems Biotech AG accelerates research capabilities.
- None.
LTBP1 is key regulator of TGF-β, a major driver of fibrosis.
Latest target identified from company’s platform in collaboration with Dualsystems Biotech AG.
SAN DIEGO, Dec. 15, 2022 (GLOBE NEWSWIRE) -- aTyr Pharma, Inc. (Nasdaq: LIFE), a biotherapeutics company engaged in the discovery and development of first-in-class medicines from its proprietary tRNA synthetase platform, today announced new findings from its tRNA synthetase platform. The target for a naturally occurring fragment of Aspartyl-tRNA Synthetase (DARS) was identified as latent transforming growth factor beta binding protein 1 (LTBP1).
LTBP1 is an extracellular matrix protein and key regulator of transforming growth factor beta (TGF-β), a central player in the pathogenesis of fibrotic diseases. The company expects to present additional findings around the interaction between LTBP1 and this fragment of DARS at an upcoming scientific conference.
“The extracellular functionality of the many splice variants and other natural fragments of tRNA synthetases is a burgeoning area of immunobiology. Elucidating the relationship between these fragments and biological pathways involved with human disease is a paradigm shift for understanding the unique role these fragments play in regulating our immune environment and helps to establish their clinical utility,” said Paul Schimmel, Ph.D., Professor of Molecular Medicine at The Scripps Research Institute and Director and Founder of aTyr. “The ability to identify the targets of tRNA synthetase fragments provides the opportunity for many therapeutic applications of a new class of medicines based on this platform.”
“We continue to generate exciting discoveries and build upon our platform with yet another target identified from our library of extracellular tRNA synthetase protein fragments,” said Sanjay S. Shukla, M.D., M.S., President and CEO of aTyr. “This work, which was conducted in collaboration with Dualsystems Biotech AG, a highly specialized company that uses cutting-edge technology to provide custom proteomic services, has helped us to accelerate our drug discovery efforts. The identification of LTBP1, a key target implicated in fibrosis and immune regulation, and its interaction with this fragment of DARS may provide an opportunity to generate a potential new therapeutic candidate.”
