MUC7 (mucin 7) is the lower molecular weight (200- 300kDa) mucin of the two types of oral cavity mucins, and is also called MG2. The other type of mucin, MG1, has high molecular weight (1000kDa). This gene is localized to human chromosome 4q13-q21, and is highly polymorphic in nature. This protein is composed of three domains namely, 4 and 1 potential N- glycosylation sites at its either ends, and a tandem repeat domain located centrally. MUC7 is composed of 68% carbohydrate and 30% protein. This protein has a molecular weight of 180kDa, and is highly expressed in sublingual and submandibular glands.

Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: MUC7 (mucin 7) has anti-bacterial, anti-viral and anti-fungal properties. It is expressed in the airway secretions of asthmatics. Variants in this gene are linked to decreased susceptibility to asthma in African-American population. In patients with rheumatoid arthritis, this protein is highly sulfated. MUC7*6/*6 polymorphism is linked to higher oral hygiene, as well as higher chances of dental caries.
