  • Calreticulin is a soluble, endoplasmic reticulum-resident protein and a molecular chaperone for glycoproteins. We have reconstituted the binding of recombinant calreticulin to two glycoprotein substrates, vesicular stomatitis virus G protein and influenza hemagglutinin, in vitro. The binding was found to be direct and to require monoglucosylated, asparagine-linked oligosaccharides on the substrate glycoprotein but no other cellular factors. The binding could be modulated in vitro by incubation… CONTINUE READING
