Surrogate R-spondins for tissue-specific potentiation of Wnt Signaling.

WebRspo proteins function have remained obscure. Recently published work has indicated that Rspo proteins can exert their potentiating effects on Wnt signalling through direct interaction with the extracellular regions of ZNRF3 or RNF43, ultimately inducing formation of a complex comprising ZNRF3/ RNF43, Rspo and LGR4/5/6 (ref. 16).
