Frizzled-7 (FZD7), also known as FzE3, is a member of the G-protein coupled receptor Fz/Smo family that functions as a receptor for Wnt proteins. It plays a critical role in the beta-catenin canonical signaling pathway by activating disheveled proteins, inhibiting GSK-3 kinase, and promoting nuclear accumulation of beta-catenin. This recombinant protein is expressed in human 293 cells (HEK293) and features a C-terminal human IgG1 Fc tag.
- Expressed from human 293 cells (HEK293) with Gln 33 - Leu 185 amino acid sequence.
