Product Details

Description

The gene fragment corresponding to amino acids 25-559 of the human glypican-3 (GPC3) is expressed in mammalian cells and then is fused with the 6xHis-Myc-tag at the N-terminus. The resulting protein has been validated to be an active protein in the functional ELISA. It can bind to the anti-GPC3 antibody, and the EC50 is 4.739-7.092 ng/ml. Its purity is greater than 92.4% measured by SDS-PAGE. On the gel, this protein migrated to the molecular weight band of 70-90 kDa. The endotoxin of this protein is less than 1.0 EU/ug determined by the LAL method. GPC3 is a cell-surface glycoprotein and has important functions in signaling including cell growth, embryogenesis, and differentiation. GPC3 upregulation has been found in hepatocellular carcinoma (HCC), while GPC3 is absent in normal and cirrhotic liver. GPC3 has recently been identified as a potential hepatocellular carcinoma (HCC) diagnostic and therapeutic target.

Target Background

Function
Cell surface proteoglycan that bears heparan sulfate. Negatively regulates the hedgehog signaling pathway when attached via the GPI-anchor to the cell surface by competing with the hedgehog receptor PTC1 for binding to hedgehog proteins. Binding to the hedgehog protein SHH triggers internalization of the complex by endocytosis and its subsequent lysosomal degradation. Positively regulates the canonical Wnt signaling pathway by binding to the Wnt receptor Frizzled and stimulating the binding of the Frizzled receptor to Wnt ligands. Positively regulates the non-canonical Wnt signaling pathway. Binds to CD81 which decreases the availability of free CD81 for binding to the transcriptional repressor HHEX, resulting in nuclear translocation of HHEX and transcriptional repression. Inhibits the dipeptidyl peptidase activity of DPP4. Plays a role in limb patterning and skeletal development by controlling the cellular response to BMP4. Modulates the effects of growth factors BMP2, BMP7 and FGF7 on renal branching morphogenesis. Required for coronary vascular development. Plays a role in regulating cell movements during gastrulation.
