Abstract
Provided are compositions comprising newly identified protein fragments of aminoacyl-tRNA synthetases, polynucleotides that encode them and complements thereof, related agents, and methods of use thereof in diagnostic, drug discovery, research, and therapeutic applications.
Claims11
A therapeutic composition, comprising a pharmaceutically-acceptable carrier and an antibody or antigen-binding fragment thereof that exhibits binding specificity for an isolated aminoacyl-tRNA synthetase (AARS) polypeptide selected from SEQ ID NOs:
- 12, 14, 24, and 26 or an epitope comprising at least 5 amino acids selected from SEQ ID NOs:
- 32 and 94, wherein the composition has a purity of at least about 90% on a protein basis and less than about 10 EU endotoxin/mg protein.
