Application

Anti-MAGI2 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.

Biochem/physiol Actions

The gene MAGI2 (membrane associated guanylate kinase, WW and PDZ domain containing 2) encodes a scaffolding protein that functions in the assembly of epithelial tight junction enhancing epithelial integrity. It negatively regulates cell migration and proliferation via PTEN (phosphatase and tensin homolog), a protein involved in cell growth and apoptosis. It has been implicated in celiac disease and ulcerative colitis.

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.

General description

The gene MAGI2 (membrane associated guanylate kinase, WW and PDZ domain containing 2) is mapped to human chromosome 7q21 and spans 1.4 megabases. It contains 21 exons encoding a 2410 amino acid protein that contains nine potential protein-protein interaction domains. These domains include one Guk (guanylate kinase-like) domain, two WW domains and six PDZ domains.
