Histidyl-tRNA synthetase (HARS) also known as histidine-tRNA ligase, is an enzyme which in humans is encoded by the HARS gene. ^{[5] [6]}

Function

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. ^[7] The gene is located in a head-to-head orientation with HARSL on chromosome five, where the homologous genes share a bidirectional promoter. ^[5]

Clinical significance

The gene product is a frequent target of autoantibodies in the human autoimmune disease polymyositis/dermatomyositis. ^[7]

Interactions

HARS has been shown to interact with EEF1B2 ^[8] and EEF1G. ^[8]
