Mediates the endocytosis of plasma glycoproteins to which the terminal sialic acid residue on their complex carbohydrate moieties has been removed. The receptor recognizes terminal galactose and N-acetylgalactosamine units. After ligand binding to the receptor, the resulting complex is internalized and transported to a sorting organelle, where receptor and ligand are disassociated. The receptor then returns to the cell membrane surface. Interacts with LASS2. Expressed exclusively in hepatic parenchymal cells. Calcium is required for ligand binding. Hepatic asialoglycoprotein receptor subunit 2
