Anti-ELFN2 antibodies are used in the immunodetection of the protein extracellular leucine rich repeat and fibronectin type III domain containing 2. In humans, the canonical protein has a reported length of 820 amino acid residues and a mass of 89.7 kDa. Its subcellular localization is in the membrane. It is notably expressed in the cerebellum. ELFN2 is reported to inhibit phosphatase activity of protein phosphatase 1 (PP1) complexes. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include dJ63G5.3 (putative Leucine rich protein), leucine-rich repeat and fibronectin type-III domain-containing protein 6, leucine-rich repeat-containing protein 62, and protein phosphatase 1 regulatory subunit 29. ELFN2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of ELFN2 antibodies have been mentioned in research publications and have associated citations. Immunofluorescence is a widely used application for these antibodies. Western Blot, Immunocytochemistry, and Immunohistochemistry are also common applications.
