1. A therapeutic composition, comprising an isolated aspartyl-tRNA synthetase (DRS) polypeptide of up to about 280 amino acids in length that comprises SEQ ID NO:16 or an amino acid sequence that is at least 95% identical to SEQ ID NO:16, wherein the polypeptide has an extracellular signaling activity and a solubility of at least about 5 mg/mL, and wherein the composition has a purity of at least about 95% on a protein basis and less than about 10 EU endotoxin/mg protein. |
