Summaries for QARS Gene

Entrez Gene Summary for QARS Gene

  • 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. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2013]

GeneCards Summary for QARS Gene

QARS (Glutaminyl-TRNA Synthetase) is a Protein Coding gene. Diseases associated with QARS include microcephaly, progressive, seizures, and cerebral and cerebellar atrophy and diffuse cerebral and cerebellar atrophy-intractable seizures-progressive microcephaly syndrome. Among its related pathways are Metabolism and Gene Expression. GO annotations related to this gene include glutamine-tRNA ligase activity.
