Anti-TMEFF2 antibodies are used in the immunodetection of the protein transmembrane protein with EGF like and two follistatin like domains 2. In humans, the canonical protein has a reported length of 374 amino acid residues and a mass of 41.4 kDa. It has been described to be a secreted protein. Up to 3 different isoforms have been reported for this protein. It is reported to be highly expressed in adult and fetal brain, spinal cord and prostate. A member of the Tomoregulin protein family, TMEFF2 is believed to be a survival factor for hippocampal and mesencephalic neurons. Post-translational modifications have been described, including O-glycosylation. Synonyms for this target antigen include HPP1, TENB2, TPEF, TR, TR-2, tomoregulin-2, cancer/testis antigen family 120, member 2, and CT120.2. TMEFF2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some TMEFF2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
