PL 7 Human
Threonyl-tRNA Synthetase Human Recombinant
Catalog No. ENZ-304

Synonyms:
Threonyl-tRNA synthetase cytoplasmic, EC 6.1.1.3, Threonine-tRNA ligase, ThrRS, MGC9344, PL-7, TARS.

Introduction:
Threonyl-tRNA Synthetase is a member of the aminoacyl-tRNA synthetase family, key enzymes of protein biosynthesis which charge tRNA molecules with the respective amino acids. This 83 kDa protein is an autoantigen recognized by PL-7 antibodies which occur in a subset of patients with polymyositis and dermatomyositis. Preliminary data suggest that PL-7 antibodies (similar to Jo-1 antibodies) indicate an increased risk for lung involvement, but this needs to be confirmed for a larger number of cases.
