Anti-TMEM231 antibodies are used in the immunodetection of the protein transmembrane protein 231. In humans, the canonical protein has a reported length of 316 amino acid residues and a mass of 36.1 kDa. Its subcellular localization is in the cell projections. Up to 3 different isoforms have been reported for this protein. It is notably expressed in the hippocampus, fallopian tube, cerebral cortex, caudate, and bronchus. A member of the TMEM231 protein family, TMEM231 is reported to be a transmembrane component of the tectonic-like complex, a complex localized at the transition zone of primary cilia and acting as a barrier that prevents diffusion of transmembrane proteins between the cilia and plasma membranes. Post-translational modifications have been described, including glycosylation. TMEM231 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some TMEM231 antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. ELISA, Western Blot, Immunocytochemistry, and Immunofluorescence are also common applications.
