Aminoacyl-tRNA synthetases catalyze the aminoacylation of tRNA by their cognate amino acid. Because of their central role in linking amino acids with nucleotide triplets contained in tRNAS, aminoacyl-tRNA synthetases are thought to be among the first proteins that appeared in evolution. Isoleucine-tRNA synthetase belongs to the class-I aminoacyl-tRNA synthetase family and has been identified as a target of autoantibodies in the autoimmune disease polymyositis/dermatomyositis. Alternatively spliced transcript variants have been found. [provided by RefSeq, Nov 2012]

A study in the blowfly *Calliphora stygia* identified 22 candidate ionotropic receptors (IRs) in adult antennae, including co-receptors IR8a, IR25a, and IR76b, and representatives from 10 of 13 conserved antennal IR groups [Leitch et al. DOI: 10.1186/s12864-015-1466-8].
