DKK-1 蛋白, Rhesus Macaque (HEK293, Fc)

DKK-1 Proteinas are potent antagonists of canonical Wnt signaling, inhibiting LRP5/6-Wnt interactions and forming a ternary complex with KREMEN to promote LRP5/6 internalization. In addition to its proapoptotic function by antagonizing KREMEN1 independently of Wnt, DKK-1 also exhibits antiapoptotic activity. DKK-1 Protein, Rhesus Macaque (HEK293, Fc) is the recombinant Rhesus Macaque-derived DKK-1 protein, expressed by HEK293 , with C-mFc labeled tag.

DKK1 蛋白通过多种机制发挥经典 Wnt 信号传导的有效拮抗剂的作用。它抑制LRP5/6和Wnt之间的相互作用，并与跨膜蛋白KREMEN形成三元复合物，促进LRP5/6的内化。值得注意的是，DKK1 不仅以不依赖 Wnt 的方式拮抗 KREMEN1 的促凋亡功能，而且还表现出抗凋亡活性。该蛋白参与肢体发育，调节 Wnt 信号以确保正常的肢体模式。通过其 C 端富含 Cys 的结构域，DKK1 与 LRP5 和 LRP6 相互作用，特别是与 LRP5 的 β 螺旋桨区域 3 和 4 结合。这种相互作用进一步受到 MESD 和/或 KREMEN 的影响，共同导致 Wnt 介导的信号传导减弱。此外，DKK1 与 LRP6 和 KREM1 形成三元复合物，突显其在调节关键细胞过程以及与 Wnt 信号转导中涉及的关键蛋白相互作用方面的多方面作用。
