Activation (right): Wnt protein binds to the LRP5/6 receptor and the Frizzled co-receptor to activate signalling pathways. With the help of protein complexes with Disheveled (Dsh), Axin, and Adenomatous Polyposis coli, this receptor complex inhibits the phosphorylation of β-catenin (APC) causing β-catenin accumulation in the cytoplasm and translocated to the nucleus. Inactivation pathway (left): sclerostin will inhibit Wnt signalling pathway causing dissociation of LRP 5/6 complex and frizzled receptor.14,29,33,34) LRP, lipoprotein receptor-related protein; GSK3, glycogen synthase kinase 3; APC, adenomatous polyposis coli; Dsh, disheveled.
