About AARS2

Cytogenetic location: 6p21.1 Genomic coordinates (GRCh38): 6:44,298,731-44,313,347 (from NCBI)

This gene has 2 transcripts (splice variants), 195 orthologues, 2 paralogues and is associated with 5 phenotypes. Ubiquitous expression in small intestine (RPKM 2.7), ovary (RPKM 2.7) and 25 other tissues.

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 that specifically aminoacylates alanyl-tRNA. Mutations in this gene are a cause of combined Oxidative Phosphorylation deficiency 8.
