Active GMP Recombinant Human DKK1 Protein

• Cat.No.: DKK1-01HG
• Product Overview: Recombinant human DKK1 protein, was expressed in CHO-K1 cell-derived in an animal component free process under cGMP guidelines.

Specification

• Description: Dickkopf-associated protein 1 (Dkk-1) is the initial member of the Dickkopf protein family, which includes Dkk-1, Dkk-2, Dkk-3, Dkk-4 and the related protein Soggy. dkk protein is a secreted protein with two conserved cysteine-rich structural domains. Each structural domain contains 10 cysteine residues. Human mature Dkk-1 is a glycosylated protein with a molecular weight of 40 KD. Dkk-1 acts as an antagonist of Wnt signaling, and Dkk-1 is expressed throughout development and antagonizes Wnt-7a during limb development. The balance between Wnt signaling and Dkk-1 inhibition is critical for bone formation and internal environmental stability. Insufficient or excessive Dkk-1 activity in bone leads to increased or decreased BMD, respectively. In adults, Dkk-1 is expressed in osteoblasts, osteocytes and neurons. Brain ischemia induces Dkk-1 expression, leading to neuronal death.
