抗-CD207 兔抗

HPA011216    Human Protein Atlas characterization data

Langerin (CD207) is a C-type lectin, which is expressed on Langerhans cells. It contains a C-type carbohydrate recognition domain (CRD) in its extracellular region. It also contains a Ca²⁺-dependent sugar binding region. It is a type II transmembrane protein, and its extracellular region also contains the neck region. This neck region forms coiled-coils of α-helices which give rise to oligomers of CD207. It contains a proline-rich motif (WPREPPP) in its intracellular domain, which in turn is composed of 43 amino acids. This proline-rich motif might be involved in signal transduction. CD207 gene is localized to human chromosome 2p13.

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.

Langerin (CD207) is an endocytic receptor which is involved in the formation of Birbeck granules, which are a part of the endosomal compartments exclusive to Langerhans cells. It recognizes the surface glucoconjugates present on pathogens such as, human immunodeficiency virus (HIV), and internalizes them into Birbeck granules. It therefore, prevents the transfer of HIV from Langerhans cells to T-cells, by degrading it. It forms the first step in antigen processing and presentation to immune cells. It recognizes a wide range of pathogens such as, Mycobacterium leprae, herpes simplex virus 2, and fungi such as, Malassezia furfur and Candida species. CD207 also binds to measles virus and presents it to CD4⁺ T cells.

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.
