KARS1 - lysyl-tRNA synthetase 1 Gene
Also Known as KRS; KARS; KARS2; LEPID; CMTRIB; DEAPLE; DFNB89
Species: Homo sapiens
About KARS1
This gene has 12 transcripts (splice variants), 226 orthologues, 4 paralogues and is associated with 8 phenotypes. Ubiquitous expression in testis (RPKM 57.5), lymph node (RPKM 40.9) and 25 other tissues.
Summary
Aminoacyl-tRNA synthetases are a class of Enzymes that charge tRNAs with their cognate Amino acids. Lysyl-tRNA synthetase is a homodimer localized to the cytoplasm which belongs to the class II family of tRNA synthetases. It has been shown to be a target of autoantibodies in the human autoimmune diseases, polymyositis or dermatomyositis. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
