If terminal sialic acid residues are removed from glycoproteins, the resulting proteins are known as asialoglycoproteins.
[1][2] In rats, the exposure of subterminal galactose or GalNAc residues may assist in receptor-mediated endocytosis of asialoglycoproteins by asialoglycoprotein receptors on Kuppfer cells.
The human ortholog of this gene is non-functional, but hepatocyte asialoglycoprotein receptors are functional in both humans and rats.
