Anti-LRRN1 antibodies are used in the immunodetection of the protein leucine rich repeat neuronal 1. In humans, the canonical protein has a reported length of 716 amino acid residues and a mass of 80.7 kDa. Its subcellular localization is in the membrane. It is notably widely expressed in many tissue types. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include fibronectin type III, immunoglobulin and leucine rich repeat domains 3, neuronal leucine-rich repeat protein 1, and leucine-rich repeat neuronal protein 1. LRRN1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some LRRN1 antibodies may have been used in research and have associated citations. ELISA and Western Blot are common applications for these antibodies.
