Background: R-Spondin 3

Roof plate-specific spondin 3 (RSPO3), also called cysteine-rich and single thrombospondin domain containing-1 (Cristin1), is member of the R-Spondin family of proteins which are involved in the activation and regulation of Wnt signaling pathway. The R-Spondin family, consisting of 4 members, are extracellular glycoproteins which share ~60% amino acid (aa) homology and a conserved protein structure (1). Similar to other R-Spondins, RSPO3 contains two adjacent cysteine-rich furin-like domains with one potential N-glycosylation site, followed by a thrombospondin (TSP1) motif and a C-terminal tail rich in basic residues. The furin-like domains are needed for beta -catenin stabilization (2, 3). Cynomologus RSPO3 shares 97% and 88% aa sequence identity with human and mouse RSPO3, respectively. While every member of the R-Spondin family positive modulators of Wnt/ beta -catenin signaling, each one has a distinct expression pattern (1 - 5). In mouse, RSPO3 is critical for development of the placental labyrinthine layer, probably by promoting VEGF expression and thus vascular development (6, 7). It is found in the roof plate, tail, somites, otic vesicles, cephalic mesoderm, truncus arteriosus, atrioventricular canal of the developing heart, and strongly but transiently in developing limbs (5, 7). R-Spondins regulate Wnt/ beta -catenin by competing with the Wnt antagonist DKK-1 for binding to the Wnt co-receptors LRP-6 and Kremen, reducing their DKK-1-mediated internalization (8, 9). Reports differ on whether R-Spondins bind LRP-6 directly (10). RSPO3 has also been identified as an oncogene (11).
