Antigen Description
Histidyl-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 58 kDa protein is an autoantigen recognized by Jo-1 antibodies which occur in 33% of patients with polymyositis and dermatomyositis. Jo-1 antibodies indicate an increased risk for lung involvement, and the disease tends to take a severe course with poor response to therapy.
