    Protocol

    Specificity / Sensitivity

    MUC1 (VU4H5) Mouse Monoclonal Antibody detects endogenous levels of total MUC1. This antibody does not cross-react with other mucin proteins.

    Species Reactivity:

    Human

    Source / Purification

    Monoclonal antibody (isotype: IgG1k) is produced by immunizing a BALB/c mouse with MUC1 60 mer tandem repeats (BSA conjugated).

    Background

    Mucins represent a family of glycoproteins characterized by repeat domains and dense O-glycosylation (1). MUC1 (or mucin 1) is aberrantly overexpressed in most human carcinomas. Increased expression of MUC1 in carcinomas reduces cell-cell and cell-ECM interactions. MUC1 is cleaved proteolytically, and the large ectodomain can remain associated with the small 25 kDa carboxy-terminal domain that contains a transmembrane segment and a 72-residue cytoplasmic tail (1). MUC1 interacts with ErbB family receptors and potentiates ERK1/2 activation (2). MUC1 also interacts with β-catenin, which is regulated by GSK-3β, PKCγ, and Src through phosphorylation at Ser44, Thr41, and Tyr46 of the MUC1 cytoplasmic tail (3-5). Overexpression of MUC1 potentiates transformation (6) and attenuates stress-induced apoptosis through the Akt or p53 pathways (7,8).
