Recombinant Human Glypican 3 Protein Summary

Details of Functionality
Measured by its binding ability in a functional ELISA. When Recombinant Human Glypican 3 is immobilized at 0.5 μg/mL (100 µL/well), the concentration of Recombinant Human FGF basic 146 aa (Catalog # 233-FB) that produces 50% of the optimal binding response is approximately 0.6-3 ng/mL.
Source
Mouse myeloma cell line, NS0-derived human Glypican 3 protein
Met1-His559 with a C-terminal 6-His tag
Accession #
N-terminal Sequence
No results obtained: Gln25 predicted, Ser359 & Val483
Structure / Form
Glypican 3 is subject to endoproteolytic processing by proprotein convertases (PC). By amino acid sequencing, three peptides (the first with a blocked N-terminus most likely starts with Gln25, the second peptide starts with Ser359 after a furin cleavage site, and the third peptide starts with Val483) are present in the recombinant GPC3 preparation. Peptides 2 and 3 are detected at a 1:1 ratio. All three peptides remained associated via disulfide bonds.

Background

Glypicans (GPC) are a family of heparan sulfate proteoglycans that are attached to the cell surface by a glycosylphosphatidylinositol (GPI) anchor. Six members of this family have been identified in mammals (GPC1-GPC6). All glypican core proteins contain an N-terminal signal peptide, a large globular cysteine-rich domain (CRD) with 14 invariant cysteine residues, a stalk-like region containing the heparan sulfate attachment sites, and a C-terminal GPI attachment site. While glypican proteins do not share strong amino acid sequence identity (they range from 17-63%), the conserved cysteine residues in their CRDs suggests similarity in their
three‑dimensional structure (1, 2).

Mutations in GPC3 cause a rare disorder in humans, Simpson-Golabi-Behmel Syndrome, which is characterized by pre and postnatal overgrowth of multiple tissues and organs and an increased risk for developing embryonic tumors (3). These features are also present in the mouse knock-out of GPC3 indicating that GPC3 regulates cell survival and inhibits cell proliferation during development (4). Glypican 3 has been implicated in regulating many different signaling pathways including: IGF, FGF, BMP and Wnt. An endoproteolytic processing of GPC3 by proprotein convertases is required for the modulation of Wnt signaling (5). Direct interaction with FGF-basic has been observed and is mediated by the heparan sulfate chains (6).
