Localization

Cytoplasm

Specificity

This monoclonal antibody recognizes the peptide core of gastric mucin M1 (recently identified as Mucin 5AC. Its epitope is located in the N-terminal cysteine rich part of the peptide core of MUC5AC. Its epitope is destroyed by beta-mercaptoethanol. This mucin 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

Mucin 5, subtype AC (MUC5AC) is a gel-forming secreted mucin that functions as a protective barrier on surface of epithelial tissues (1-2). MUC5AC is expressed primarily by goblet cells of the surface epithelium, including in the stomach, respiratory tract, gall bladder, endocervix, and endometrium (1-3). Human MUC5AC is located on chromosome 11p15.5, consisting of 5654 amino acids and has a N-terminus, tandem-repeat region (TRR), and a C-terminus, with a theoretical molecular weight of ~585 kDa (1-4). More specifically, the N-terminus contains four von Willebrand factor type D domains, where D1 also has a leucine zipper pattern (1). The TRR is further divided into nine CysD domains and four PTS-rich tandem repeats (1). Finally, the C-terminus has a D4-, B-, C-, and CK-domain (1). The TRR is a site of heavy O-glycosylation that functions in gel and polypeptide formation (1,3).

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).
