General description

Dickkopf-related protein 3, also known as Dickkopf-3, or Dkk-3, or hDkk-3, and encoded by the gene DKK3/ REIC is a member of the dickkopf family. DKK3 is a 350 amino acid secreted glycoprotein that is composed of an N-terminal signal peptide and two conserved cysteine-rich domains, which are separated by a 12 amino acid linker region. This secreted protein is involved in embryonic development through its interactions with the Wnt signaling pathway. The expression of this gene is decreased in a variety of cancer cell lines and it may function as a tumor suppressor gene.


Purified recombinant fragment of human DKK3 expressed in E. Coli


Anti-DKK3, clone 4G7 Antibody is an antibody against DKK3 for use in western blotting & flow cytometry.

Flow Cytometry Analysis: A 1:200-400 dilution from a representative lot detected DKK3 in MCF-7 cells.
