Anti-MRPS18-3 antibodies are used in antigen-specific immunodetection in biological samples. The target MRPS18-3 is a known alias name of the protein mitochondrial ribosomal protein S18A, encoded by the MRPS18A gene in humans. This 196-amino acid residue protein is known to be involved in mitochondrial translation and protein translation, among other biological processes. It is localized to the mitochondria of the cell. It is reported to be widely expressed in many tissue types. Other synonyms for MRPS18-3 include HumanS18b and MRP-S18-3.
