R-spondin-3 is a protein that in humans is encoded by the RSPO3 gene.^[3][4][5]

Function

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.^[5]

During embryonic development, RSPO3 is expressed in the tail bud and the posterior presomitic mesoderm of the embryo. In tissue engineering, R-spondin 3 has been used to differentiate pluripotent stem cells into paraxial mesoderm progenitors^[6]
