Anti-MRPL4 antibodies are used in the immunodetection of the protein mitochondrial ribosomal protein L4. In humans, the canonical protein has a reported length of 311 amino acid residues and a mass of 34.9 kDa. Its subcellular localization is in the mitochondria. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Universal ribosomal protein uL4 protein family, MRPL4 is known to be involved with mitochondrial translation. Synonyms for this target antigen include L4mt, 39S ribosomal protein L4, mitochondrial, mitochondrial large ribosomal subunit protein uL4m, and CGI-28. MRPL4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Some MRPL4 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
