Anti-TMEM16A DOG1, clone DG1/447

1 mg/ml in sterile PBS, BSA free, sodium azide free. Expression of TMEM16A (DOG1) protein is elevated in the gastrointestinal stromal tumors (GISTÆs), c-kit signaling-driven mesenchymal tumors of the GI tract. TMEM16A is rarely expressed in other soft tissue tumors, which, due to appearance, may be difficult to diagnose. Immunoreactivity for TMEM16A has been reported in 97.8 percent of scorable GISTÆs, including all c-kit negative GISTÆs. Overexpression of TMEM16A has been suggested to aid in the identification of GISTs, including Platelet-Derived Growth Factor Receptor Alpha (PDGFR alpha) mutants that fail to express c-kit antigen. The overall sensitivity of TMEM16A and c-kit in GISTÆs is nearly identical: 94.4% vs. 94.7%. Protein function: Calcium-activated chloride channel (CaCC) which plays a role in transepithelial anion transport and smooth muscle contraction. Required for the normal functioning of the interstitial cells of Cajal (ICCs) which generate electrical pacemaker activity in gastrointestinal smooth muscles. Acts as a major contributor to basal and stimulated chloride conductance in airway epithelial cells and plays an important role in tracheal cartilage development. [The UniProt Consortium]
