HOMOLOGY

FAMILY

class-II aminoacyl-tRNA synthetase family

CATEGORY

enzyme

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytosolic

basic FUNCTION	responsible for the synthesis of histidyl-transfer RNA, which is essential for the incorporation of histidine into proteins
	catalyzing the transfer of the aminoacyl moiety from histidyl-adenylate to the terminal adenosine (A76) of tRNA
	key role for histidyl-tRNA synthetase in the pathogenesis of idiopathic inflammatory myopathy
	can likely trigger both innate and adaptive immune responses that culminate in severe muscle inflammation that is the hallmark of idiopathic inflammatory myopathy
