Distribution of an asialoglycoprotein receptor on rat hepatocyte cell surface
Direct ferritin immunoelectron microscopy was applied to visualize the distribution of the hepatocyte cell surface of the asialoglycoprotein receptor which is responsible for the rapid clearance of serum glycoproteins and lysosomal catabolism. For this purpose, rabbit antibody against the purified hepatic binding protein specific for asialoglycoproteins was prepared and coupled to ferritin by g...
متن کاملAn in vivo Method for Determination of Endosomal Distribution of Both Ligand and Asialoglycoprotein Receptor in Rat Liver
Introduction Alcoholic liver injury is a significant medical problem throughout the world. Protein trafficking pathways, including endocytosis, appear to be especially susceptible to the deleterious effects of alcohol. Using the asialoglycoprotein receptor (ASGPR) as a model, we have studied ethanol-induced alterations in the process of receptormediated endocytosis (RME). The ASGPR, a hepatocyt...
متن کاملImmunocytochemical localization of the receptor for asialoglycoprotein in rat liver cells
We used high-resolution immunocytochemistry on ultrathin frozen sections labeled with colloidal gold to study the subcellular distribution of the asialoglycoprotein receptor in rat liver. The receptor was localized along the entire hepatocyte plasma membrane, including the bile capillary membrane, but was scarce intracellularly. Sinusoidal lining (Kupffer) cells and blood cells showed no immuno...
متن کاملRecycling of the Hepatic Asialoglycoprotein Receptor in Isolated Rat Hepatocytes
We recently reported that the dissociation of internalized receptor-1261-asialo-orosomucoid (ASOR) complexes by isolated hepatocytes is a biphasic process; most complexes dissociate rapidly but 25-50% dissociate slowly (Oka, J. A., and Weigel, P. H. J. Biol. Chern. 258, 10253-10262). Cells were allowed to endocytose a pulse of surface-bound '''I-ASOR, and were washed and then incubated at 37 "C...
متن کاملDifferential ligand binding by two subunits of the rat liver asialoglycoprotein receptor.
The rat liver asialoglycoprotein receptor consists of two types of subunits, a predominant polypeptide designated rat hepatic lectin 1 (RHL-1) and a minor polypeptide, RHL-2/3, that comes in two differentially glycosylated forms. The exact stoichiometry and arrangement of the subunits in the RHL oligomer are not known. The carbohydrate-recognition domain of RHL-2/3 has been prepared by limited ...
