A number of ELISA Kits are available that target Srp54a, an alias of the protein, signal recognition particle 54. The human protein, encoded by the gene SRP54, is a member of the GTP-binding SRP family, SRP54 subfamily. The protein's cellular localization is indicated to be cytoplasmic and nuclear. Homology is conserved in other species, such as Mouse, Rat, Fly, Yeast, Zebrafish, Frog, Chicken.
