Anti-TMEM30B antibodies are used in the immunodetection of the protein transmembrane protein 30B. In humans, the canonical protein has a reported length of 351 amino acid residues and a mass of 38.9 kDa. Its subcellular localization is in the cell membrane. A member of the CDC50/LEM3 protein family, TMEM30B is reported to be an accessory component of a P4-ATPase flippase complex which catalyzes the hydrolysis of ATP coupled to the transport of aminophospholipids from the outer to the inner leaflet of various membranes and ensures the maintenance of asymmetric distribution of phospholipids. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include cell cycle control protein 50B and P4-ATPase flippase complex beta subunit TMEM30B. TMEM30B gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Some TMEM30B antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
