Informations sur le gène

human ... CLDN7(1366)

Description générale

CLDN7 (claudin-7) belongs to the family of tight junction proteins called claudins, which are responsible for the maintenance of epithelial barrier function. This family has at least 24 members, and they are all membrane proteins. It has a short N-terminal facing the cytosol, two extraplasmic domains, and cytosolic C-terminal. Its spans the membrane four times.

Immunogène

Claudin-7 recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project 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. We also provide Prestige Antibodies® protocols and other useful information.

Actions biochimiques/physiologiques

CLDN7 (claudin-7) prevents the invasion and migration of human lung cancer cells, and induces apoptosis by activating caspases, post cisplatin treatment of lung cancer cells. It interacts with CD44 and EpCAM, and might form a membrane-anchoring protein complex, which helps it to reside in the plasma membrane. It is up-regulated in colon cancer, where it facilitates tumorigenesis. Its expression is also associated with inflammatory bowel disease (IBD) and colitis-associated cancer. It is either completely inactivated or under-expressed in human breast cancer, and is also linked with relapse of the same. Studies on human breast cancer MCF-7 cell line, show that tumor necrosis factor (TNF)α induces the expression of CLDN7, which leads to accumulation of β-catenin in the cytosol. This way CLDN7 regulates apoptosis of MCF-7 cell line. It is over-expressed in epithelial ovarian cancer, where it might be involved in its invasion.

Caractéristiques et avantages

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.
