Gene Gene information from NCBI Gene database.
Entrez ID 57505
Gene name Alanyl-tRNA synthetase 2, mitochondrial
Gene symbol AARS2
Synonyms (NCBI Gene)
AARSLCOXPD8LKENPMT-ALARSMTALARS
Chromosome 6
Chromosome location 6p21.1
Summary The protein encoded by this gene belongs to the class-II aminoacyl-tRNA synthetase family. Aminoacyl-tRNA synthetases play critical roles in mRNA translation by charging tRNAs with their cognate amino acids. The encoded protein is a mitochondrial enzyme t

Protein name Alanine--tRNA ligase, mitochondrial (EC 6.1.1.7) (Alanyl-tRNA synthetase) (AlaRS) (Protein lactyltransferase AARS2) (EC 6.-.-.-)
Protein function Catalyzes the attachment of alanine to tRNA(Ala) in a two-step reaction: alanine is first activated by ATP to form Ala-AMP and then transferred to the acceptor end of tRNA(Ala). Also edits incorrectly charged tRNA(Ala) via its editing domain (Pu
