Recombinant Human MUC1 Protein, GST-tagged

• Cat.No.: MUC1-5745H
• Product Overview: Human MUC1 partial ORF ( NP_877418.1, 315 a.a. - 420 a.a.) recombinant protein with GST-tag at N-terminal.

Specification

• Description: This gene is a member of the mucin family and encodes a membrane bound, glycosylated phosphoprotein. The protein is anchored to the apical surface of many epithelia by a transmembrane domain, with the degree of glycosylation varying with cell type. It also includes a 20 aa variable number tandem repeat (VNTR) domain, with the number of repeats varying from 20 to 120 in different individuals. The protein serves a protective function by binding to pathogens and also functions in a cell signaling capacity. Overexpression, aberrant intracellular localization, and changes in glycosylation of this protein have been associated with carcinomas. Multiple alternatively spliced transcript variants that encode different isoforms of this gene have been reported, but the full-length nature of only some has been determined. [provided by RefSeq

Q&As

What are the structural characteristics of the MUC1 protein?

The MUC1 protein consists of a short extracellular region, a transmembrane region, and a long intracellular region. The extracellular region is rich in sugar chains, which make the MUC1 protein adherent.

What is the role of the MUC1 protein in cancer?

In cancer, the expression of the MUC1 protein usually increases abnormally and changes in glycosylation occur. This can affect cell adhesion, proliferation, and invasion, promoting the spread and metastasis of cancer cells.

Is the MUC1 protein involved in the immune system?

Yes, the MUC1 protein is closely related to the immune system. In some cases, abnormal expression of the MUC1 protein may interfere with the function of immune cells, thereby reducing the immune response.

In which diseases is MUC1 involved in the diagnosis and treatment?

MUC1 protein is overexpressed in many types of cancer, including breast, stomach, ovarian, and others. Therefore, the MUC1 protein can be a potential target for cancer diagnosis and treatment.

What are the main physiological functions of MUC1 protein?

The MUC1 protein mainly plays the role of protecting and lubricating the mucosal surface. It prevents bacteria and other pathogens from entering our body, while also helping to maintain cell-to-cell adhesion.

Is the MUC1 protein associated with other diseases?

MUC1 protein may be associated with a number of other diseases, such as lung infections and inflammatory bowel disease. However, the research related to cancer is more extensive and in-depth.
