Anti-RPS25 antibodies are used in the immunodetection of the protein ribosomal protein S25. In humans, the canonical protein has a reported length of 125 amino acid residues and a mass of 13.7 kDa. Its subcellular localization is in the cytoplasm. A member of a the Eukaryotic ribosomal protein eS25 protein family, RPS25 is a known component of the small ribosomal subunit. Synonyms for this target antigen include eS25, 40S ribosomal protein S25, small ribosomal subunit protein eS25, and S25.
