Background

MUC1 is a large cell surface mucin glycoprotein expressed by most glandular and ductal epithelial cells and some hematopoietic cell lineages. It is expressed on most secretory epithelium, including mammary gland and some hematopoietic cells. It is expressed abundantly in lactating mammary glands and overexpressed abundantly in >90% breast carcinomas and metastases. Transgenic MUC1 has been shown to associate with all four cebB receptors and localize with erbB1 (EGFR) in lactating glands. The MUC1 gene contains seven exons and produces several different alternatively spliced variants. The major expressed form of MUC1 uses all seven exons and is a type I transmembrane protein with a large extracellular tandem repeat domain. The tandem repeat domain is highly O glycosylated and alterations in glycosylation have been shown in epithelial cancer cells.

Tissue Specificity

Expressed on the apical surface of epithelial cells, especially of airway passages, breast and uterus. Also expressed in activated and unactivated T-cells. Overexpressed in epithelial tumors, such as breast or ovarian cancer and also in non-epithelial tumor cells. Isoform 7 is expressed in tumor cells only. .

Applications

IHC

Field of Research

Cancer, Cell Type Markers, Cytoskeleton/ECM, ECM Proteins, Extracellular Matrix, Invasion/Microenvironment, Signal Transduction, Tags & Cell Markers, Tumor Associated, Tumor Immunology, Tumor-Associated Antigens

Purification

Ascites

Concentration

Adding 1 ml of PBS buffer will yield a concentration of 100 μg/ml.

Form

Lyophilized

Reconstitution

Add 1ml of PBS buffer will yield a concentration of 100ug/ml.

Function

The alpha subunit has cell adhesive properties. Can act both as an adhesion and an anti-adhesion protein. May provide a protective layer on epithelial cells against bacterial and enzyme attack.
