Cayman Asialoglycoprotein Receptor 1 Rabbit Polyclonal Antibody

Asialoglycoprotein receptor 1 is a calcium-dependent C-type lectin receptor.¹ It is composed of a carbohydrate recognition domain, which primarily recognizes galactosides such as D-galactose and N-acetyl-D-galactosamine (GalNAc), stalk region, transmembrane domain, and cytoplasmic domain. Asialoglycoprotein receptor 1 is expressed in hepatocytes, and alternative splicing produces both long and short isoforms.² The long isoform localizes to the cell membrane, while the short isoform exists as a soluble form that is both secreted and found in the cytoplasm. The asialoglycoprotein receptor is a trimer that is commonly formed by two H1 subunits and one H2 subunit.¹ It is involved in the clearance of desialylated serum glycoproteins and hepatotropic virus entry via endocytosis. Ectopic expression of the gene encoding asialoglycoprotein receptor 1 (ASGR1) increases binding of hepatitis E virus to cells in vitro.³ Knockdown of ASGR1 increases survival and decreases liver injury and plasma TNF-α and IL-1β levels in a mouse model of sepsis.⁴ Decreased protein levels of asialoglycoprotein receptor 1 negatively correlate with hepatocellular carcinoma tumor grade.⁵ The asialoglycoprotein receptor has been used as a target of galactosylated drug conjugates and various lipid-based drug delivery (LBDD) platforms, including lipid nanoparticles (LNPs), liposomes, and micelles, for therapeutic and imaging applications.¹ Cayman’s Asialoglycoprotein Receptor 1 Polyclonal Antibody can be used for ELISA, immunohistochemistry (IHC; paraffin), immunoprecipitation (IP), and Western blot (WB) applications. The antibody recognizes asialoglycoprotein receptor 1 at 33 kDa from human samples. However, due to lipidation, glycation, and phosphorylation the antibody may recognize asialoglycoprotein receptor 1 at approximately 45-50 kDa.
