Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate TMEM27 in samples. An antibody specific for TMEM27 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTMEM27 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TMEM27 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TMEM27 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:TMEM27 encodes a transmembrane protein that is important for trafficking amino acid transporters to the apical brush border of proximal tubules. It also plays a role in controlling insulin exocytosis by regulating formation of the SNARE (soluble N-ethylmaleimide-sensitive-factor attachment protein receptor) complex in pancreatic beta cells. TMEM27 has an N-terminal signal sequence, followed by a noncatalytic extracellular domain, a transmembrane segment, and a cytosolic domain. The extracellular domain contains an O-glycosylation site and 2 N-glycosylation sites. Human TMEM27 shares 47.8% identity with the C-terminal end of ACE2, but it lacks an ACE2-like catalytic domain. Northern blot analysis of rat, mouse, and human tissues detected a transcript of about 1.8 kb exclusively in kidney.
