General description
MUC1 (Mucin 1) is O-glycosylated, carbohydrate rich, transmembrane glycoprotein. It has approximately 13 members in the family. It is localized on the apical surface of mucosal epithelia in the lung, eye, breast and stomach. It is overexpressed in several epithelial cancers, including pancreatic ductal adenocarcinoma. It is a heterodimer consisting of N-terminal (MUC1-N) and C-terminal (MUC1-C) subunits. N-terminal (MUC1-N) end contains tandem repeats (VNTR) which forms the mucin component.
Mucin 1 is encoded by the gene mapped to human chromosome 1q22.

Biochem/physiol Actions
MUC1 (Mucin 1) plays a major role in the formation of epithelium lining of the gastrointestinal tract. In gastrointestinal tract, it lubricates to protect the epithelia from oesophagus to the colon. It also lubricates the epithelia of some organs such as pancreas and gall bladder. It participates in the mucosal defensive system by functioning at the mucosal surface. It is directly involved in several signaling pathways as a modulator that affects oncogenesis, motility and metastasis.
Mutated MUC1 gene increases the risk of developing upper gastrointestinal cancers in Caucasian populations.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.
Linkage
Corresponding Antigen APREST86683.
Physical form
Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
