RSPO1 gene is a member of the R-spondin family. It encodes RSPO1 which is known as a secreted activator protein with two cystein-rich, furin-like domains and one thrombospondin type 1 domain. In mice, RSPO1 induces the rapid onset of crypt cell proliferation and increases intestinal epithelial healing, providing a protective effect against chemotherapy-induced adverse effects. This protein is an activator of the beta-catenin signaling cascade, leading to TCF-dependent gene activation. RSPO1 acts both in the canonical Wnt/beta-catenin-dependent pathway and in non-canonical Wnt signaling pathway, probably by acting as an inhibitor of ZNRF3, an important regulator of the Wnt signaling pathway. It also acts as a ligand for frizzled FZD8 and LRP6.
Product Name:
Mouse R-Spondin 1/RSPO1 Recombinant Protein (RPES3108)
Product Code:
RPES3108
Size:
20µg
Species:
Mouse
Expressed Host:
CHO Stable Cells
Synonyms:
R-spondin,Rspondin
Accession:
NP_619624.2
Sequence:
Met 1-Gln 265
Fusion tag:
C-His
Activity:
Measured by its ability to induce activation of ?-catenin response in a Topflash Luciferase assay using HEK293T human embryonic kidney cells. The ED50 for this effect is typically 50-200 ng/ml in the presence of 50 ng/ml recombinant mouse Wnt3a.
Endotoxin:
<1.0 EU per µg of the protein as determined by the LAL method.
Protein Construction:
A DNA sequence encoding the full length of mouse RSPO1 (NP_619624.2) (Met 1-Gln 265) was fused with a polyhistidine tag at the C-terminus.
Purity:
> 95 % as determined by SDS-PAGE
Mol Mass:
28.5 kDa
AP Mol Mass:
44 kDa
Formulation:
Lyophilized from sterile PBS, pH 7.4
Shipping:
This product is provided as lyophilized powder which is shipped with ice packs.
Stability and Storage:
Lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
