Anti-LARP4 antibodies are used in the immunodetection of the protein La ribonucleoprotein 4. In humans, the canonical protein has a reported length of 724 amino acid residues and a mass of 80.6 kDa. Its subcellular localization is in the cytoplasm. Up to 7 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. LARP4 is known to be involved with cytoskeleton organization and protein translation. Synonyms for this target antigen include La ribonucleoprotein domain family member 4, c-Mpl binding protein, and la-related protein 4. LARP4 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of LARP4 antibodies have been mentioned in research publications and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
