[Encoded by human YARS Gene, the 528-amino acid Tyrosyl-tRNA Synthetase polypeptide belongs to the Class-I Aminoacyl-tRNA Synthetase Family. Likely to be among the first proteins to appear in evolution, amino acyl-tRNA synthetases catalyze tRNA amino acylation by their cognate amino acid. Under apoptotic conditions, tyrosyl-tRNA synthetase may be secreted and cleaved into an N-terminal IL8-like cytokine fragment that harbors the catalytic site and a C-terminal EMAP II-like cytokine fragment.
