R-spondin-3 is a protein that in humans is encoded by the RSPO3 gene.This gene encodes a member of the thrombospondin type 1 repeat supergene family. In addition the protein contains a furin-like cysteine-rich region. Furin-like repeat domains have been found in a variety of eukaryotic proteins involved in the mechanism of signal transduction by receptor tyrosine kinases.
