R-Spondin 1, Human, CHO

R-Spondin-1 Protein, Human is a potent activator of the Wnt/β-catenin signaling pathway and a secretory glycoprotein that promotes the proliferation of intestinal stem cells and liver fibrosis studies, used in organoid research. This is a recombinant human RSPO1 protein expressed in CHO cells with a C-6*His tag.

R-Spondin-1, Human (RSPO1) is a potent activator of the Wnt/β-catenin signaling pathway and a secretory glycoprotein belonging to the R-Spondin family. RSPO1 homotetramers synergize with LRP5/6 via LGR4/5/6 and activate the Wnt/β-catenin pathway by inhibiting DKK1/Kremen-mediated LRP6 endocytosis. RSPO1 promotes β-catenin nuclear translocation, drives HSC activation in liver fibrosis, inhibits adipocyte thermogenic gene expression, and promotes intestinal epithelial proliferation. RSPO1/R-spondin-1 Protein, Human (CHO, His) is a recombinant human RSPO1 protein expressed in CHO cells with a C-6*His tag.
