Anti-TMEM203 antibodies are used in the immunodetection of the protein transmembrane protein 203. In humans, the canonical protein has a reported length of 136 amino acid residues and a mass of 15.8 kDa. Its subcellular localization is in the ER. TMEM203 is reported to be involved in regulation of cellular calcium homeotasis. Synonyms for this target antigen include HBeAg-binding protein 1. TMEM203 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Indicated applications for TMEM203 antibodies listed below include Western Blot.
