LRP5 Mutations Linked to High Bone Mass Diseases Cause Reduced LRP5 Binding and Inhibition by SOST

Open access

Abstract

The low density lipoprotein (LDL) receptor-related protein 5 (LRP5) is a co-receptor for Wnt proteins and a major regulator in bone homeostasis. Human genetic studies have shown that recessive loss-of-function mutations in LRP5 are linked to osteoporosis, while on the contrary, dominant missense LRP5 mutations are associated with high bone mass (HBM) diseases. All LRP5 HBM mutations are clustered in a single region in the LRP5 extracellular domain and presumably result in elevated Wnt signaling in bone forming cells. Here we show that LRP5 HBM mutant proteins exhibit reduced binding to a secreted bone-specific LRP5 antagonist, SOST, and consequently are more refractory to inhibition by SOST. As loss-of-function mutations in the SOST gene are associated with Sclerosteosis, another disorder of excessive bone growth, our study suggests that the SOST-LRP5 antagonistic interaction plays a central role in bone mass regulation and may represent a nodal point for therapeutic intervention for osteoporosis and other bone diseases.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
