Data Sheet
Recombinant Human R-spondin 1 (J2-004) is expressed in E. coli.
This product is a bioactive domain consisting of 21 to 146 amino acids which contain two adjacent cysteine-rich furin-like domains (Fu1 and Fu2).
Fu1 binds to the extracellular domain of ZNRF3 and RNF43, and Fu2 binds to the extracellular domain of LGR4/5/6.

| Background | R-spondin 1 (roof plate-specific spondin 1), also known as Cristin 3, is one of the R-spondin family members that regulates to the activation of canonical WNT/β-catenin signaling. In the absence of R-spondin, Frizzled (Fz) is endocytosed by being ubiquitinated by the binding of the ubiquitin ligase RNF43/ZNRF3, Fz on the cell membrane decreases, and Wnt signals are not activated enough. Conversely, in the presence of R-spondin, RNF43/ZNRF3 forms trimers with LGR and R-spondin and is endocytosed, making it unable to ubiquitinate Fz. As a result, Fz on the cell membrane increases, and Wnt signals are strongly activated. Organoid culture is typically utilized niche factors that act on Wnt, EGF, BMP and Notch signals that control stem cell differentiation. Among these signals, R-spondin 1 contributes to the activation of Wnt signals. |
