General description
ASGR2 (asialoglycoprotein receptor 2) is one of the two subunits of the hetero-oligomeric ASGP-R, which is expressed specifically on hepatocytes. It is also called H2 and shares high homology with the other subunit called H1. ASGP-R is present on the plasma membrane of hepatocytes, towards the sinusoidal side, and undergoes endocytic recycling. This receptor is a type II membrane protein, and thus, ASGR2 has its N-terminal towards the cytoplasm, one transmembrane region, a stalk region and a Ca2+-dependent CRD (carbohydrate recognition domain). The molecular weight of this subunit is ~ 50kDa.

Application
All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.
The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions
ASGR2 (asialoglycoprotein receptor 2) forms a subunit of ASGR, which internalizes desialylated glycoproteins, and transports them to lysosomes. It is also a receptor for hepatitis B virus (HBV), the chronic infection of which can affect the male reproductive system. As ASGR is also expressed in human testis, it might be responsible for HBV infection in the luminal compartment of testis. This receptor is also involved in the immune regulation and inflammatory processes in hepatocytes, and promotes liver cell toxicity. An alternatively spliced form of ASGR2 subunit, called sH2a is found in serum of healthy individuals. The serum level of this form is changed in liver fibrosis, and defines the status of hepatocyte function. Thus, it has potential as a non-invasive marker for liver function and fibrosis.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.

During acute or chronic hepatitis B virus (HBV) infection, the virus can invade the male reproductive system, pass through the blood-testis barrier and integrate into the germ line, resulting in abnormal spermatozoa. However, the pathway remains unclear. The asialoglycoprotein receptor

It has been recently identified that hepatocytes can act as cytotoxic effectors and can kill contacted cells by way of CD95 ligand-CD95 and perforin-dependent pathways. However, it remained unknown whether hepatocyte-mediated cell killing is indiscriminant or is directed toward targets
