SOST is a secreted antagonist of WNT signaling that acts by binding to LRP5/6 (Li et al, 2005; Semenov et al, 2005; Veverka et al, 2005). Binding of SOST requires the first two YWTD EGF repeats of LRP5/6 and appears to inhibit WNT signaling by preventing the formation of the LRP5/6:FZD receptor complex (Li et al, 2005; Semenov et al, 2005).
