A number of ELISA Kits are available that target phenylalanyl-tRNA synthetase, alpha subunit, an alias of the protein, phenylalanyl-tRNA synthetase subunit alpha. The human protein, encoded by the gene FARSA, is an enzyme and member of the Class-II aminoacyl-tRNA synthetase family, Phe-tRNA synthetase alpha subunit type 2 subfamily. The protein's cellular localization is indicated to be cytoplasmic. Additional synonyms or past names for this protein may include: CML33, FARSL, FARSLA, FRSA, PheHA. Homology is conserved in other species, such as Mouse, Rat, Zebrafish, Frog, Chicken.
