Gene Gene information from NCBI Gene database.
Entrez ID 23395
Gene name Leucyl-tRNA synthetase 2, mitochondrial
Gene symbol LARS2
Synonyms (NCBI Gene)
HLASALEURSPRLTS4mtLeuRS
Chromosome 3
Chromosome location 3p21.31
Summary This gene encodes a class 1 aminoacyl-tRNA synthetase, mitochondrial leucyl-tRNA synthetase. Each of the twenty aminoacyl-tRNA synthetases catalyzes the aminoacylation of a specific tRNA or tRNA isoaccepting family with the cognate amino acid. [provided b
