Gene Gene information from NCBI Gene database.
Entrez ID 55687
Gene name TRNA mitochondrial 2-thiouridylase
Gene symbol TRMU
Synonyms (NCBI Gene)
LCAL3MTO2MTU1TRMTTRMT1
Chromosome 22
Chromosome location 22q13.31
Summary This nuclear gene encodes a mitochondrial tRNA-modifying enzyme. The encoded protein catalyzes the 2-thiolation of uridine on the wobble positions of tRNA(Lys), tRNA(Glu), and tRNA(Gln), resulting in the formation of 5-taurinomethyl-2-thiouridine moieties
