|Product Overview :||Recombinant Human FZD7(Gln33 - Leu185) fused with a human IgG1 Fc tag at the C-terminus was expressed in CHO.|
|Description :||Frizzled-7 is a member of the Frizzled family of unconventional G-protein-coupled glycoprotein receptors for the Wnt signaling pathway. The Wnt genes encode a large family of glycoproteins that are essential in development and tissue maintenance. Like other Frizzled family members, Frizzled-7 contains a divergent N-terminal signal peptide (amino acid (aa) 1 - 32), a highly conserved extracellular cysteine-rich domain (CRD, aa 44 - 169), a variable-length linker region (aa 170 ‑ 256), a seven-pass transmembrane region (aa 257 - 549), and a variable-length C-terminal cytoplasmic domain (aa 550 - 574). The CRD, which comprises the binding site for Wnts and other ligands such as Syndecan 4 and fibronectin, spans about 130 amino acid residues and contains ten invariant cysteine residues. Expressed alone, it can compete with native Frizzled to inhibit Wnt canonical signaling. Within aa 33 - 185, human Frizzled-7 shares ~99% aa identity with human, rat, canine and bovine Frizzled-7. Mature Frizzled-7 also shares 80% aa identity with Frizzled-1 and Frizzled-2. Roles for Frizzled-7 have been determined in both canonical Wnt/ beta -Catenin-mediated signaling and non‑canonical planar cell polarity and calcium pathways. During development, Frizzled-7 is expressed during gastrulation and in the fetal gut, kidney and lung where it is thought to influence tissue morphogenesis via non-canonical signaling pathways. In the adult, Frizzled-7 is expressed in skeletal muscle, especially in satellite cells that mediate muscle regeneration in response to Wnt-7a. It is expressed in embryonic stem cells (ES), contributing to self-renewal signaling (7). It has been implicated in mesenchymal-to-epithelial transition in colorectal cancer. Frizzled-7 mRNA has also been detected in adult heart and placenta.|
|Predicted N Terminal :||Gln33|
|Form :||Lyophilized from a 0.2 μm filtered solution in PBS.|
|Bio-activity :||Measured by its binding ability in a functional ELISA. In a 100 µL reaction mixture containing biotinylated rmWnt-5a at 100 ng/mL and rhFrizzled-7/Fc Chimera dilutions at 0.1-8,000 ng/mL, the concentration of rhFrizzled-7/Fc Chimera that produces 50% of the optimal binding response is found to be approximately 20-80 ng/mL.
Optimal concentrations should be determined by each laboratory for each application.
