Anti-FCHSD2 antibodies are used in the immunodetection of the protein FCH and double SH3 domains 2. In humans, the canonical protein has a reported length of 740 amino acid residues and a mass of 84.3 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Up to 3 different isoforms have been reported for this protein. FCHSD2 is a reported adaptor protein that plays a role in endocytosis via clathrin-coated pits. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include NWK1, SH3MD3, F-BAR and double SH3 domains protein 2, FCH and double SH3 domains protein 2, SH3 multiple domains 3, and NWK. FCHSD2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some FCHSD2 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.
