WebJul 2, 2013 · R-spondins (RSPOs) are secreted growth factors that potentiate Wnt/β-catenin signaling by binding to leucine-rich repeat–containing G protein–coupled receptors (LGRs). RSPOs also bind to the transmembrane E3 ubiquitin ligases RNF43 and ZNRF3 and trigger their internalization. WebMar 21, 2024 · RNF43 mutation constitutes an important mutated driver gene for the Serrated Neoplasia pathway in both the sporadic and familial Polyposis settings.

WebJun 11, 2024 · It seems to be clear that PA domain mediates the interaction with R-spondins (RSPO)- endogenous negative regulators of RNF43 and ZNRF3. RSPO 1–4 are secreted proteins, which reduce plasma membrane level of RNF43 and ZNRF3 in a leucine-rich repeat-containing G-protein coupled receptors (LGR) 4/5/6 dependent (RSPO1 and 4) or … 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).
