Gene Gene information from NCBI Gene database.
Entrez ID 4141
Gene name Methionyl-tRNA synthetase 1
Gene symbol MARS1
Synonyms (NCBI Gene)
CMT2UILFS2ILLDMARSMETRSMRSMTRNSSPG70TTD9
Chromosome 12
Chromosome location 12q13.3
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. The encoded protein is a component of the multi-tRNA synthetase co
