This receptor, a C-type lectin, is involved in the recognition and binding of terminal galactose on the glycan chains and is responsible for the clearance of asialoglycoproteins, and redetermined as an Ashwell-Morell Receptor (126).

Sia covers penultimate galactose residue that is recognized by an asialoglycoprotein receptor.
At the same time, a hepatic galactose specific receptor (asialoglycoprotein receptor) from a rabbit liver was characterized (120) and a similar clearance mechanism for the desialylated cells, for erythrocytes in the rabbit was reported for the first time (121,122).
Mammalian hepatocytes possess large numbers of high-affinity, cell-surface receptors (asialoglycoprotein receptor, ASGP-R) that can bind asialoglycoproteins [13-15].

Crystal structure of the carbohydrate recognition domain of the H1 subunit of the asialoglycoprotein receptor.
For example, competition for clearance by the asialoglycoprotein
receptor of the liver between asialylated intestinal ALP and asialoglycoproteins
can lead to increased serum concentrations of intestinal ALP (5).
