Supplementary information

The Asialoglycoprotein Receptor 1 (ASGR1) also known as ASGPR 1 or asialoglycoprotein receptor is a well-known protein with a critical role in the mechanism of recognizing and binding to asialoglycoproteins. It has a molecular mass of approximately 46 kDa. ASGR1 is expressed mostly in liver cells specifically hepatocytes. The unique characteristic of this receptor is its lectin-like nature which allows it to bind to specific sugar moieties present on desialylated glycoproteins. Through receptor-mediated endocytosis it facilitates their removal from the bloodstream.
Biological function summary

The function of ASGR1 extends significantly. It operates as part of the asialoglycoprotein receptor complex interfacing directly with the ligand proteins to mediate endocytosis. This process is essential in most mammalian systems for maintaining serum glycoprotein homeostasis. By clearing desialylated glycoproteins from circulation ASGR1 helps prevent potential adverse effects these molecules might cause like immune activation or interference with other biological functions.

Pathways

ASGR1 is integral to glycoprotein clearance pathways. It actively participates in the hepatic clearance pathway ensuring the regulation of serum glycoprotein levels. The removal of asialoglycoproteins involves interactions with several other hepatic proteins such as GalNAc transferase which can further facilitate the remodeling of glycoconjugates. Understanding these interactions is key for comprehending how the liver maintains overall metabolic balance.

ASGR1 is linked to certain liver-related conditions. Dysfunction or aberrant expression of the ASGR1 receptor can relate to elevated levels of serum glycoproteins which might be observed in liver cirrhosis. Elevated glycoproteins can exacerbate the progression of liver diseases. Furthermore ASGR1 protein interaction with viral glycoproteins has implications in hepatitis infections where it may inadvertently facilitate viral entry into hepatocytes affecting liver function and contributing to disease pathology.

Target data

Transmembrane protein predominantly expressed on hepatocytes that plays a key role in endocytosis of plasma glycoproteins that lack terminal sialic acid residues. Specifically recognizes terminal galactose and N-acetylgalactosamine residues, facilitating the clearance of desialylated glycoproteins from circulation. Plays thereby a role in a variety of physiological processes, such as removal of desialylated platelets, elimination of activated lymphocytes and maintenance of serum glycoprotein homeostasis (PubMed : 25485912). Plays a role in the removal of desialylated platelets by activating a feedback loop regulating thrombopoietin (TPO) expression via the JAK2-STAT3 signaling pathway (PubMed : 25485912). Contributes also to recognition and elimination of activated lymphocytes by hepatocytes that can act as cytotoxic effectors (PubMed : 21656538). May also play a physiological role in the regulatory network of lipid homeostasis (By similarity). Upon ligand binding, the receptor-ligand complex is internalized and trafficked to a sorting organelle, where dissociation occurs. The receptor is then recycled back to the cell surface.. (Microbial infection) Plays an essential role in ACE2-independent SARS-CoV-2 entry by acting as alternate receptor.
