Human R-Spondin1 PicoKine® Quick ELISA Kit, Carrier-free

R-spondin-1 is a secreted protein that in humans is encoded by the Rspo1 gene. It is mapped to chromosome 1p34. This gene encodes 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 repeat-containing G-protein coupled receptors (LGR proteins) and positively regulates the Wnt 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. Alternative splicing results in multiple transcript variants.
