Kremen protein 2 (Kremen2)

Receptor for Dickkopf proteins.

Cooperates with DKK1/2 to inhibit Wnt/beta-catenin signaling by boosting the endocytosis of Wnt receptors LRP5 and LRP6 (PubMed:12050670).

Plays a role in limb development; attenuates Wnt signaling in the developing limb to allow normal limb patterning and can also negatively regulate bone formation (PubMed:18505822). .
