'The meprin A homo-oligomer is a highly glycosylated, secreted zinc metalloprotease of the astacin family and metzincin superfamily. This isoform of meprin is composed of disulfide-bonded dimers of alpha subunits that further associate to form large, secreted megadalton complexes of 10 or more subunits. The aim of this study was ... More
Interaction with the 5D3 monoclonal antibody is regulated by intramolecular rearrangements but not by covalent dimer formation of the human ABCG2 multidrug transporter.

Human ABCG2 is a plasma membrane glycoprotein working as a homodimer or homo-oligomer. The protein plays an important role in the protection/detoxification of various tissues and may also be responsible for the multidrug-resistant phenotype of cancer cells. In our previous study we found that the 5D3 monoclonal antibody shows a ... More
