These Signal Recognition Particle 19kDa ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. Signal Recognition Particle 19kDa is an alias of the human SRP19 gene, which encodes the protein, signal recognition particle 19. The protein is a known component of the signal recognition particle (SRP) complex, a ribonucleoprotein complex that mediates the cotranslational targeting of secretory and membrane proteins to the endoplasmic reticulum (ER) (By similarity). The SRP19 protein is 144 amino acid residues in length and 16.2 kilodaltons in mass. However, as many as 3 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. Other names for this target antigen include signal recognition particle 19 kDa protein, signal recognition particle 19kD, and signal recognition particle 19kDa.
