General description
IGF2R (insulin-like growth factor 2 receptor) is a transmembrane glycoprotein. It is one of the two mannose 6-phosphate (M6P) receptors found in mammalian cells. It has 15 consecutive repeating regions making up a repetitive structure. The domains 3 and 9 contain M6P-binding sites. Domain 5 contains M6P-N-acetylglucosamine residue- binding site. The IGF-II binding site is located in domain 11. It belongs to p-lectin family and has a molecular weight of 300kDa. It has an N-terminal, a small cytosolic C-terminal, a transmembrane region and a large exosolic domain.
Immunogen
Cation-independent mannose-6-phosphate receptor precursor recombinant protein epitope signature tag (PrEST)
Application
Anti-IGF2R antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.

Biochem/physiol Actions
IGF2R (insulin-like growth factor 2 receptor) regulates multiple cellular processes such as, cell survival, proliferation, migration and invasion, endocytosis, lysosomal trafficking. Its ligands are divided in two major classes- mannose 6-phosphate (M6P)-containing and non-M6P. The former class includes lysosomal acid hydrolases, TGF (transforming growth factor)-β, proliferin, thyroglobulin, and granzyme B, while the latter class includes mitogen, plasminogen, insulin-like growth factor II (IGF-II) and retinoic acid. Binding of plasminogen to IGF2R leads to the conversion and activation of plasminogen to plasmin. This gene is also mutated in multiple cancers where it might lead to tumorigenesis. It is down-regulated in breast cancer where it supposedly facilitates tumorigenesis. It decreases the metastatic capacity of receptor-deficient SCC-VII squamous cell carcinoma cells, which in turn is modulated by M6P-binding site within domain 3.
Features and Benefits
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.
Linkage
Corresponding Antigen APREST86865.
Physical form
Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
