Anti-MRPS27 antibodies are used in the immunodetection of the protein mitochondrial ribosomal protein S27. In humans, the canonical protein has a reported length of 414 amino acid residues and a mass of 47.6 kDa. Its subcellular localization is in the mitochondria and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably expressed in hepatocellular carcinoma tissues compared with adjacent non-tumoral liver tissues. A member of the Mitochondrion-specific ribosomal protein mS27 protein family, MRPS27 is reported to be a RNA-binding component of the mitochondrial small ribosomal subunit (mt-SSU) that plays a role in mitochondrial protein synthesis. Synonyms for this target antigen include 28S ribosomal protein S27, mitochondrial, mitochondrial 28S ribosomal protein S27, mitochondrial small ribosomal subunit protein mS27, and S27mt. A number of MRPS27 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Flow Cytometry, Immunofluorescence, and Immunohistochemistry are also common applications.
