QARS Antibody (N-term) Blocking Peptide

Synthetic peptide

Product Information
Primary Accession P47897
Clone Names 71228135
Additional Information
Gene ID 5859
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.

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.
