Recombinant Human Asialoglycoprotein receptor 1 (ASGR1), Truncated

Uniprot Id

P07306

Target Species

Human

Target Name

ASGR1

Target Full Name

Asialoglycoprotein receptor 1

Target Function

Mediates the endocytosis of plasma glycoproteins to which the terminal sialic acid residue on their complex carbohydrate moieties has been removed. The receptor recognizes terminal galactose and N-acetylgalactosamine units. After ligand binding to the receptor, the resulting complex is internalized and transported to a sorting organelle, where receptor and ligand are disassociated. The receptor then returns to the cell membrane surface.

Target Subcellular Location

[Isoform H1a]: Membrane; Single-pass type II membrane protein.; [Isoform H1b]: Secreted.

Target Tissue Specificity

Expressed exclusively in hepatic parenchymal cells.

Target Research Area

Signal Transduction

Target Background

This gene encodes a subunit of the asialoglycoprotein receptor. This receptor is a transmembrane protein that plays a critical role in serum glycoprotein homeostasis by mediating the endocytosis and lysosomal degradation of glycoproteins with exposed terminal galactose or N-acetylgalactosamine residues. The asialoglycoprotein receptor may facilitate hepatic infection by multiple viruses including hepatitis B, and is also a target for liver-specific drug delivery. The asialoglycoprotein receptor is a hetero-oligomeric protein composed of major and minor subunits, which are encoded by different genes. The protein encoded by this gene is the more abundant major subunit. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
