Localization

Specificity
Mucin 5AC glycoprotein (MUC5AC) is a 641kDa glycoprotein belonging to the superfamily of mucins. Mucins are high molecular weight glycoproteins produced by epithelial cells and can be divided into two families; secretory mucins and membrane bound mucins. MUC5AC is a mucus-forming secreted mucin that is found in normal gastric and tracheo-bronchial mucosa, but absent from normal colon. MUC5AC expression is present in primary ovarian mucinous cancer but usually absent in colorectal adenocarcinoma, thus showing an expression pattern opposite to MUC2. Together with a panel of antibodies, Anti-MUC5AC may be useful for differential identification of primary mucinous ovarian tumors from colon adenocarcinoma metastatic to the ovary. MUC5AC antibodies may also be useful for identification of intestinal metaplasia as well as in the identification of pancreatic carcinoma and pre-cancerous changes vs. normal pancreas.

Background: MUC5AC
Given that MUC5AC is the primary mucin produced and secreted by cells lining airway, it is understandable that its expression is dysregulated in a number of respiratory diseases (1,3,5,6). For instance, MUC5AC is overexpressed in asthma and the protein is also more highly glycosylated, specifically fucosylated, in the disease state (1,3,7). Additionally, its overproduction is a key feature in chronic obstructive pulmonary disease (COPD) contributing to mucosal blockage (6). Multiple pathways are associated with overproduction of MUC5AC including NFkappaB, the primary pathway for production and secretion, and also the MAPK and STAT6 pathways (3). In addition to conventional, synthetic therapeutics agents, researchers are exploring natural MUC5AC inhibitors such as flavonoids, glycosides, and steroids to treat associated disorders (3).
