Asialoglycoprotein receptor 1 (ASGR1)

Mediates the endocytosis of plasma glycoproteins to which the terminal sialic acid residue in 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.
