Variations in the rate of secretion of different glycosylated forms of rat α1-acid glycoprotein

Open full text 11 citations

Abstract

Various studies have shown that oligosaccharides play an important role in the intracellular transport and secretion of glycoproteins. We show here a difference in the rate of secretion of two mature glycoforms of a single protein, alpha 1-acid glycoprotein. This indicates the existence of kinetically different pathways for these two forms for transport from the medial Golgi to the extracellular medium.
