Product Summary for MUC2 Antibody (CCP58) - Azide and BSA Free

Immunogen

A synthetic peptide of 29 amino acids, KYPTTTPISTTTMVTPTPTPTGTQTPTTT from MUC2 protein, coupled to KLH. (Uniprot: Q02817)

Epitope

GTQTP(GlyThrGlnThrPro)

Localization

Cytoplasmic and Cell surface

Specificity

Recognizes a single glycoprotein of 520kDa, identified as mucin 2 (MUC2). This monoclonal antibody shows no cross-reaction with human milk fat globule membranes, MUC1, or MUC3. Its epitope has been defined as GTQTP(GlyThrGlnThrPro). Mucins are high molecular weight glycoproteins, which constitute the major component of the mucus layer that protects the gastric epithelium. MUC2 is specifically expressed in goblet cells of the small intestine in about 65% of colonic carcinomas and about 40% of gastric carcinomas. MUC2 is rarely expressed outside of the GI tract with the exceptions of mucinous carcinoma of breast and clear cell-type carcinomas of the ovary.

Background: MUC2

MUC2, also called mucin 2, is a member of the mucin protein family which are heavily glycosylated, high molecular weight proteins that are produced by goblet cells in epithelial tissues including the intestinal and respiratory tract (1). Mucins can form gels and function in lubrication of mucosal surfaces which serve as a protective barrier of the epithelial lining and an innate host defense (1). Mucins are divided into two groups based on whether they are membrane-bound or secreted, where MUC2 belongs to the secretory group (1,2). Secreted mucins have a distinctive composition characterized by a large central exon "mucin domain" containing O-glycosylated tandem repeat regions rich in proline, threonine, and serine residues, non-repetitive domains, and cysteine-rich domains (1,2). The mucin domain is flanked by 5' and 3' D domains, a B-like domain, a C-like domain, and a Ck-domain (1,2). MUC2 was the first secretory mucin identified in humans (3,4). Full-length MUC2 protein is synthesized as 5179 amino acids (aa) in length with a theoretical molecular weight of ~540 kDa (5).

Changes or perturbations to MUC2 expression has been associated with a number of disease pathologies (1-4, 6). Specifically, altered MUC2 composition has been indicated in colorectal cancer, inflammatory bowel diseases (IBD) including ulcerative colitis and Chron's disease, and chronic obstructive pulmonary disease (COPD) (1-4, 6). In general, decreased or reduced MUC2 expression is associated with colorectal cancer disease progression and development of IBD (1-4, 6). Additionally, studies have found that upon intestinal infection due to parasites or bacteria MUC2 expression is increased, as is overall mucus secretion (3, 6).
