Dkk-1 Luminex Assays

Dkk-1 (Dickkopf related protein 1) is a secreted antagonist of Wnt/beta-Catenin signaling. It interacts with LRP-6, and internalized complexes of Dkk-1/LRP-6/Kremen 2 can downregulate Wnt signaling. The balance between Wnt signaling and Dkk-1 inhibition is critical for bone formation and homeostasis. In addition, Dkk-1 can act as either a tumor suppressor or promoter of metastasis.
