Glypican 3 (GPC3), also known as GTR2-2, intestinal protein OCI-5 and MXR7, is a member of the heparan sulfate (HS) proteoglycan family (1).  In mammals, six glypican family members have been identified, all sharing a conserved core protein that is linked to the cell membrane by a glycosylphosphatidylinositol (GPI) anchor. GPC3 can be cleaved by furin to produce two subunits that are linked by disulfide bonds: a 40 kDa N-terminal alpha subunit that can be secreted into the blood and a 30 kDa membrane-bound C-terminal beta subunit containing two HS glycan chains (1-3). Several isoforms of GPC3 due to alternative splicing have been reported (1). Within the mature extracellular domain, human GPC3 shares 96% amino acid sequence identity with both mouse and rat GPC3.  GPC3 is an important biomarker present in the serum of hepatocellular carcinoma patients, which distinguishes benign from cancerous nodules (4). Glypican 3 is over-expressed in hepatocellular carcinomas and binding of GPC3 to CD81 promotes development of carcinomas by activation of Hippo pathways in hepatocytes (5).  Our Avi-tag Biotinylated Recombinant  Glypican 3  features biotinylation at a single site contained within the Avi-tag, a unique 15 amino acid peptide.  Protein orientation will be uniform when bound to streptavidin-coated surface due to the precise control of biotinylation and the rest of the protein is unchanged so there is no interference in the protein's bioactivity.
