Homo sapiens

Also known as PCH6; ArgRS; RARSL; DALRD2; PRO1992

Gene ID: 57038 | Gene type: protein coding

About RARS2

Cytogenetic location: 6q15 Genomic coordinates (GRCh38): 6:87,513,938-87,589,987 (from NCBI)

This gene has 58 transcripts (splice variants), 195 orthologues, 1 paralogue and is associated with 3 phenotypes. Ubiquitous expression in adrenal (RPKM 9.8), testis (RPKM 8.4) and 25 other tissues.

Summary

This nuclear gene encodes a protein that localizes to the mitochondria, where it catalyzes the transfer of L-arginine to its cognate tRNA, an important step in translation of mitochondrially-encoded proteins. Defects in this gene are a cause of pontocerebellar hypoplasia type 6 (PCH6). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]
