About Physiocrines
Physiocrines act as extracellular signaling molecules to orchestrate physiological homeostasis in response to stress, which often involves an immune system response. Physiocrines are naturally occurring human proteins derived from tRNA synthetases. They play fundamental roles in human physiology as part of the resolution of different types of immune responses. As potent endogenous modulators of inflammation, Physiocrines offer the opportunity for modulating biological pathways through new naturally occurring mechanisms, many of which have multiple therapeutic advantages, including improved selectivity, efficacy and reduced side effect profiles compared to many existing anti-inflammatory therapeutics.

About aTyr Pharma
aTyr Pharma develops biotherapeutics based on Physiocrine biology. aTyr's key programs currently focus on grave, rare immune disorders. These diseases are serious potentially life threatening autoimmune conditions, for which there are currently no effective, safe, long term treatments. aTyr established a dominant intellectual property estate to protect the core therapeutics, as well as associated diagnostics. The privately held biotech was founded by The Scripps Research Institute Professor Paul Schimmel, a leading aminoacyl tRNA synthetase scientist, and is backed by top life sciences investors including Alta Partners, Cardinal Partners, Domain Associates and Polaris Ventures.
