Product Specifications

Immunogen

Hydrogen fluoride deglycosylated milk mucin.

Reactivity Notes

Mouse reactivity reported in scientific literature (PMID: 1372533) No record of testing in other species.

Specificity

Reacts very little with normal tissue. Found to react with breast, colon and ovarian carcinomas and adinocarcinoma. SM3 recognises the under-glycosylated form of MUC1 and is therefore tumour specific.

Clonality

Monoclonal

Host

Mouse

Isotype

IgG2a Kappa

Background: MUC-1

Mucin 1 (MUC1), also known as episialin, EMA (epithelial membrane antigen), PEM (polymorphic epithelial mucin), and CA-15-3 antigen, is a membrane-bound type I transmembrane glycoprotein (1,2). MUC1 is typically expressed in the luminal or glandular epithelial cells of the gastrointestinal tract, breast, lungs, and more, and is often overexpressed in epithelial cancers, but also serves a protective role against infection and helps regulate inflammatory response (2,3). Human MUC1 is 1255 amino acids (aa) in length with a theoretical molecular weight of 122 kDa; however, depending on the amount of glycosylation can weigh between 250 - 500 kDa (2,4). Structurally, MUC1 consists of a N-terminal domain which contains a signal peptide, a variable number tandem repeat region (VNTR), and a SEA domain, as well a C-terminal domain which has the extracellular domain (ECD), transmembrane domain (TMD), and cytoplasmic tail (CT) (2,3). The VNTR is comprised of between 25 - 125 repeats of a 20 aa conserved sequence (3). MUC1 is heavily O-glycosylated in the VNTR and has moderate N-glycosylation sites following the VNTR and in the ECD (2). Glycosylation contributes to MUC1's functional properties (2). The MUC1 gene contains seven exons, giving rise to several MUC1 isoforms as a result of alternative splicing (2).

Overexpression of mucins, including MUC1, is a feature of many epithelial cancers (1,3,5,6). The presence of truncated glycan structures called tumor-associated carbohydrate antigens (TACAs) on MUC1 play a role in cancer progression and a loss of apical-basal polarity (5). Carbohydrate-binding partners called lectins are the primary binding partners of TACAs that give rise to the pro-tumor microenvironment and metastasis (5). Given this unique feature, TACAs are a potential target for cancer immunotherapies (5). There are a number of vaccines, drugs, and antibodies targeting MUC1 for treatment of a variety of cancers including breast, lung, and prostate (6). In addition to a role in cancer progression, MUC1, and specifically the CT portion, has been shown to have a positive, anti-inflammatory role in a variety of lung and airway infections (7).
