Anti-Signal Recognition Particle 9kDa antibodies are used in antigen-specific immunodetection in biological samples. The target Signal Recognition Particle 9kDa is a known alias name of the protein signal recognition particle 9, encoded by the SRP9 gene in humans. This 86-amino acid residue 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). It is localized to the cytoplasm of the cell. Other synonyms for Signal Recognition Particle 9kDa include ALURBP, signal recognition particle 9 kDa protein, and signal recognition particle 9kD.
