Uses
Anti-MAGI2 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project
(www.proteinatlas.org). 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

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.
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.
