Product Overview:
Recombinant Mouse Dkk2(Ser26-Ile259) fused with Leu35Pro substitution and His tag at C-terminal was expressed in E. coli.
Dickkopf related protein 2 (Dkk-2) is a member of the Dickkopf family of secreted Wnt modulators. Dkk proteins contain a signal peptide and two conserved cysteine-rich domains that are separated by a linker region. The second cysteine-rich domain mediates Dkk-2 binding activities, and its interaction with LRP beta propellers has been mapped. The 226 aa, ~35 kDa mature mouse Dkk-2 shares 99%, 96%, 96%, 96% and 94% aa identity with rat, human, dog, horse and cow Dkk-2, respectively, and can activate the canonical Wnt signaling pathway in Xenopus embryos. Dkk proteins modify Wnt engagement of a receptor complex composed of a Frizzled protein and a low-density lipoprotein receptor-related protein, either LRP5 or LRP6. When LRP6 is over-expressed, direct high-affinity binding of Dkk-2 to LRP can enhance canonical Wnt signaling. However, when Dkk-2 and LRP6 form a ternary complex with Kremen2, Wnt signaling is inhibited due to internalization of Dkk-2/LRP6/Krm2 complexes. Thus, depending on the cellular context, Dkk-2 can either activate or inhibit canonical Wnt signaling. In contrast, binding of Dkk-1 or Dkk-4 to LRP is consistently antagonistic. Dkk proteins are expressed in mesenchymal tissues and control epithelial transformations. Dkk-2 expression has been studied most in bone and eye, although it is expressed as early as periimplantation in mice. Mouse Dkk-1 or Dkk-2 deficiencies have opposite effects on bone homeostasis, despite down-regulating Wnt antagonism in both cases. Dkk-2 expression is induced by Wnts in bone, and is thought to enhance bone density by promoting terminal differentiation of osteoblasts and mineral deposition. In contrast, Dkk-1 negatively regulates late osteoblast proliferation, which limits bone density. Dkk-2-deficient mice are blind, exhibiting faulty differentiation of corneal epithelium and ectopic blood vessels in the periocular mesenchyme.
