Entrez ID 55157
Gene name Aspartyl-tRNA synthetase 2, mitochondrial
Gene symbol DARS2
Synonyms (NCBI Gene)
ASPRSLBSLMT-ASPRSmtAspRS
Chromosome 1
Chromosome location 1q25.1
Summary The protein encoded by this gene belongs to the class-II aminoacyl-tRNA synthetase family. It is a mitochondrial enzyme that specifically aminoacylates aspartyl-tRNA. Mutations in this gene are associated with leukoencephalopathy with brainstem and spinal

Protein name Aspartate--tRNA ligase, mitochondrial (EC 6.1.1.12) (Aspartyl-tRNA synthetase) (AspRS)
Protein function Catalyzes the attachment of aspartate to tRNA(Asp) in a two-step reaction: aspartate is first activated by ATP to form Asp-AMP and then transferred to the acceptor end of tRNA(Asp).
