|Other Names||Glutamine--tRNA ligase, Glutaminyl-tRNA synthetase, GlnRS, QARS|
|Target/Specificity||The synthetic peptide sequence used to generate the antibody AP7986a was selected from the N-term region of human QARS. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||Glutamine--tRNA ligase (PubMed:26869582). Plays a critical role in brain development (PubMed:24656866).|
|Cellular Location||Cytoplasm, cytosol. Cytoplasm|
|Tissue Location||Highly expressed in fetal cerebral cortex, particularly in the ventricular zone, inner subventricular zone, outer subventricular zone, and cortical plate|

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. In metazoans, 9 aminoacyl-tRNA synthetases specific for glutamine (gln), glutamic acid (glu), and 7 other amino acids are associated within a multienzyme complex. Although present in eukaryotes, glutaminyl-tRNA synthetase (QARS) is absent from many prokaryotes, mitochondria, and chloroplasts, in which Gln-tRNA(Gln) is formed by transamidation of the misacylated Glu-tRNA(Gln). Glutaminyl-tRNA synthetase belongs to the class-I aminoacyl-tRNA synthetase family.
