Summaries for KARS Gene

Entrez Gene Summary for KARS Gene

  • 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]

GeneCards Summary for KARS Gene

KARS (Lysyl-TRNA Synthetase) is a Protein Coding gene. Diseases associated with KARS include charcot-marie-tooth disease, recessive intermediate, b and deafness, autosomal recessive 89. Among its related pathways are Gene Expression and Metabolism. GO annotations related to this gene include nucleic acid binding and tRNA binding.

UniProtKB/Swiss-Prot for KARS Gene

  • Catalyzes the specific attachment of an amino acid to its cognate tRNA in a 2 step reaction: the amino acid (AA) is first activated by ATP to form AA-AMP and then transferred to the acceptor end of the tRNA. When secreted, acts as a signaling molecule that induces immune response through the activation of monocyte/macrophages. Catalyzes the synthesis of diadenosine oligophosphate (Ap4A), a signaling molecule involved in the activation of MITF transcriptional activity. Interacts with HIV-1 virus GAG protein, facilitating the selective packaging of tRNA(3)(Lys), the primer for reverse transcription initiation.

UniProtKB/Swiss-Prot:

SYK_HUMAN :
  • The N-terminal domain (1-65) of the cytoplasmic isoform is a functional tRNA-binding domain (By similarity), is required for nuclear localization, is involved in the interaction with DARS, but has a repulsive role in the binding to EEF1A1. A central domain (208-259) is involved in homodimerization and is required for interaction with HIV-1 GAG and incorporation into virions. The C-terminal domain (452-597) is not required for interaction with AIMP2.
  • Belongs to the class-II aminoacyl-tRNA synthetase family.
