About EARS2

Cytogenetic location: 16p12.2 Genomic coordinates (GRCh38): 16:23,520,754-23,557,375 (from NCBI)

This gene has 17 transcripts (splice variants), 203 orthologues, 2 paralogues and is associated with 2 phenotypes. Ubiquitous expression in thyroid (RPKM 6.6), testis (RPKM 6.4) and 25 other tissues.

Summary

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. This protein is encoded by the nuclear genome but is likely to be imported to the mitochondrion where it is thought to catalyze the ligation of glutamate to tRNA molecules. Mutations in this gene have been associated with combined Oxidative Phosphorylation deficiency 12 (COXPD12). Alternative splicing results in multiple transcript variants.
