Glypican-3/GPC3 Protein, Mouse (sf9, His)

GPC3 is a cell surface proteoglycan that regulates Hedgehog and Wnt signaling. Glypican-3/GPC3 Protein, Mouse (sf9, His) is the recombinant mouse-derived Glypican-3/GPC3 protein, expressed by Sf9 insect cells , with C-His labeled tag.

Glypican-3 (GPC3) Protein, a cell surface proteoglycan, intricately regulates signaling pathways crucial for developmental processes. It negatively modulates the hedgehog signaling pathway by competing with the hedgehog receptor PTC1 for binding to hedgehog proteins, leading to complex internalization and subsequent lysosomal degradation. Conversely, GPC3 exerts positive regulation on both canonical and non-canonical Wnt signaling pathways. In the canonical Wnt pathway, it binds to the Wnt receptor Frizzled, enhancing the interaction between Frizzled and Wnt ligands. GPC3 also binds to CD81, reducing the availability of free CD81 for binding to the transcriptional repressor HHEX, resulting in nuclear translocation of HHEX and transcriptional repression. Additionally, GPC3 inhibits the dipeptidyl peptidase activity of DPP4. Functionally, GPC3 plays essential roles in limb patterning, skeletal development, renal branching morphogenesis, coronary vascular development, and cell movements during gastrulation. This multifaceted protein exists as a heterodimer formed by disulfide linkage and interacts with various molecules, including DPP4, FGF2, WNT5A, WNT3A, WNT7B, hedgehog proteins SHH and IHH, and Wnt receptors FZD4, FZD7, and FZD8, highlighting its central role in developmental processes.
