RDI Divison of Fitzgerald Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.

Background: Plakoglobin (also known as gamma catenin) was originally identified as a component of desmones where it is found in association with desmoglein. Gamma-catenin and Beta-catenin are closely related proteins and have significant homology with theDrosphilia armadillo protein. In addition to complexing with E-cadherin, G-catenin and B-catenin have been observed in association with the intracellular domain of N-cadherin. It has been proposed that one molecule of alpha-catenin and at least one molecule of B-catenin and G-catenin simultaneously bind to a single cadherin molecule. Recently, a 19-amino acid sequence of desmoglein (Dsg1) has been recognized as critical for binding of G-catenin. This region has significant homology to catenin-binding domain of classical cadherins, suggesting a common  mechanism for G-catenin localization at both adherens junctions and desmosomes.
