Two models have been proposed to explain molecular mechanism of Dkk's inhibition role in canonical Wnt pathway: in the first model, Dkk1 competes for binding of Wnt co-receptor LRP6; in the second model, Dkk1 can form a ternary complex with LRP6 and Kremen at the presence of Kremen, and triggers the endocytosis of this ternary complex quickly. The controversies between these two models exist during these years.

现今有两种模型分别解释Dkk抑制经典Wnt信号的分子机制：在第一种模型中，一些研究者认为Dkk1主要通过在细胞外与配体Wnt竞争受体LRP6从而抑制Wnt信号；在第二种模型中，另一些研究者们则认为在Kremen存在的情况下，Dkk1通过诱导形成Dkk1-LRP6-Kremen三元复合物，并迅速诱导这个三元复合物的内吞从而发挥抑制功能。
