AVS Bio - hRSPO1-Fc

RSPO1 is a secreted activator protein with two cysteine-rich, furin-like domains and one thrombospondin type 1 domain. The encoded protein is a ligand for leucine-rich repeatcontaining G-protein coupled receptors (LGR proteins) and positively regulates the Wnt/β- catenin signaling pathway. In mice, the protein induces the rapid onset of crypt cell proliferation and increases intestinal epithelial healing, providing a protective effect against chemotherapy-induced adverse effects. Although R-spondins are unable to initiate Wnt signaling, they can potently enhance responses to low-dose Wnt proteins.
