Summaries for MARS Gene

Entrez Gene Summary for MARS Gene

  • This gene encodes a member of the class I family of aminoacyl-tRNA synthetases. These enzymes play a critical role in protein biosynthesis by charging tRNAs with their cognate amino acids. The encoded protein is a component of the multi-tRNA synthetase complex and catalyzes the ligation of methionine to tRNA molecules. [provided by RefSeq, Jan 2011]

GeneCards Summary for MARS Gene

MARS (Methionyl-TRNA Synthetase) is a Protein Coding gene. Diseases associated with MARS include Interstitial Lung And Liver Disease and Charcot-Marie-Tooth Disease, Axonal, Type 2U. Among its related pathways are Gene Expression and One carbon pool by folate. Gene Ontology (GO) annotations related to this gene include nucleotide binding and aminoacyl-tRNA ligase activity.

UniProtKB/Swiss-Prot for MARS 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.

Function for MARS Gene

Molecular function for MARS Gene

GENATLAS Biochemistry:
methionine tRNA synthetase
UniProtKB/Swiss-Prot CatalyticActivity:
ATP + L-methionine + tRNA(Met) = AMP + diphosphate + L-methionyl-tRNA(Met).
UniProtKB/Swiss-Prot EnzymeRegulation:
Enzyme activity is increased by spermidine, EEF1A1, and when the Mg(2+) concentration is increased from 5 mM to 13 mM (in vitro), possibly by promoting the dissociation of the complex between the enzyme and its product.
UniProtKB/Swiss-Prot Function:
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.

  • Charcot-Marie-Tooth disease 2U (CMT2U) [MIM:616280]: An axonal form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies (designated CMT1 when they are dominantly inherited) and primary peripheral axonal neuropathies (CMT2). Neuropathies of the CMT2 group are characterized by signs of axonal degeneration in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle weakness and atrophy. CMT2U is a slowly progressive, autosomal dominant form characterized by late-adult onset. {ECO:0000269 PubMed:23729695, ECO:0000269 PubMed:24354524}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Interstitial lung and liver disease (ILLD) [MIM:615486]: An autosomal recessive, life-threatening disorder characterized by respiratory insufficiency and progressive liver disease with onset in infancy or early childhood. Clinical features include failure to thrive, hypotonia, intermittent lactic acidosis, aminoaciduria, hypothyroidism, interstitial lung disease, pulmonary alveolar proteinosis, anemia, and liver canalicular cholestasis, steatosis, and iron deposition. {ECO:0000269 PubMed:24103465, ECO:0000269 PubMed:25913036}. Note=The disease is caused by mutations affecting the gene represented in this entry.
