|Synonyms||DOG1, ORAOV2, TAOS2, TMEM16A|
|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.|
|Cellular Location||Cell membrane; Multi- pass membrane protein. Cytoplasm. Note=Cytoplasmic localization seen in neoplastic cells of head and neck squamous cell carcinoma (HNSCC) tumors.|
|Tissue Location||Broadly expressed with higher levels in liver, skeletal muscle and gastrointestinal muscles|

Expression of DOG-1 protein is elevated in the gastrointestinal stromal tumors (GIST’s), c-kit signaling-driven mesenchymal tumors of the GI tract. DOG-1 is rarely expressed in other soft tissue tumors, which, due to appearance, may be difficult to diagnose. Immunoreactivity for DOG-1 has been reported in 97.8 percent of scorable GIST’s, including all c-kit negative GIST’s. Overexpression of DOG-1 has been suggested to aid in the identification of GISTs, including Platelet-Derived Growth Factor Receptor Alpha mutants that fail to express c-kit antigen. The overall sensitivity of DOG1 and c-kit in GIST’s is nearly identical: 94.4% vs. 94.7%.
