Histidyl-tRNA synthetase
Histidine-tRNA Ligase, histidyl-tRNA synthetase, HARS
Aminoacyl-tRNA synthetases are a class of enzymes that charge tRNAs with their cognate amino acids. The protein encoded by this gene is a cytoplasmic enzyme which belongs to the class II family of aminoacyl-tRNA synthetases. The enzyme is responsible for the synthesis of histidyl-transfer RNA, which is essential for the incorporation of histidine into proteins. The gene is located in a head-to-head orientation with HARSL on chromosome five, where the homologous genes share a bidirectional promoter. The gene product is a frequent target of autoantibodies in the human autoimmune disease polymyositis/dermatomyositis. [provided by RefSeq, Jul 2008] (from

Review
New
Miami, United States. In Curr Rheumatol Rep, Sep 2015
Histidyl-tRNA synthetase (HRS = Jo-1) represents a key autoantibody target in the anti-synthetase syndrome that is marked by myositis as well as extra-muscular organ complications including interstitial lung disease (ILD).

New
Praha, Czech Republic. In Brain, Aug 2015
Recently, a mutation in histidyl-tRNA synthetase (HARS) was identified in a single patient with a late-onset, sensory-predominant peripheral neuropathy; however, the genetic evidence was lacking, making the significance of the finding unclear.

Structural basis for recognition of G-1-containing tRNA by histidyl-tRNA synthetase.
New
Guangzhou, China. In Nucleic Acids Res, Apr 2015

Idiopathic inflammatory myopathies and the anti-synthetase syndrome: a comprehensive review.
Review
San Diego, United States. In Autoimmun Rev, 2014
Although several research methods and commercial tests are available, routine testing for anti-ARS autoantibodies (other than anti-Jo-1/histidyl-tRNA synthetase) is not widely available, sometimes leading to delays in diagnosis and poor disease outcomes.
