Clone 3H17 is a ZooMAb rabbit recombinant monoclonal antibody that specifically detects human Dickkopf-related protein 3 (DKK3).

His-tagged recombinant fragment corresponding to 300 amino acids (almost full length mature protein) from human Dickkopf-related protein 3 (DKK3).

Affinity Binding Assay: A representative lot of this antibody bound recombinant DKK3 protein with a KD of 5.7 x 10-9 in an affinity binding assay.

Immunocytochemistry Analysis: A 1:1,000 dilution from a representative lot detected DKK3 in MCF-7 cells.

Flow Cytometry Analysis: 0.1 μg from a representative lot detected DKK3 in one million MCF-7 cells.

Immunohistochemistry (Paraffin) Analysis: A 1:1,000 dilution from a representative lot detected DKK3 in human cerebral cortex tissue sections.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user

Anti-DKK3, clone 3H17 ZooMAb, Cat. No. ZRB1074, is a recombinant Rabbit monoclonal antibody that targets DKK3 and is tested for use in Affinity Binding Assay, Flow Cytometry, Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.

Dickkopf-related protein 3 (UniProt: Q9UBP4; also known as Dickkopf-3, Dkk-3, hDkk-3) is encoded by the DKK3 (also known as REIC, UNQ258/PRO295) gene (Gene ID: 27122) in human. DKK is a family of secreted glycoproteins that display Wnt inhibitory activity. They act as high affinity ligands for the transmembrane proteins Kremen1 and 2, which are known to modulate Wnt signaling. They play a role in vertebrate development via locally inhibiting Wnt-regulated processes such as antero posterior axial patterning, limb development, somitogenesis and eye formation. DKK3 is synthesized with a signal peptide (aa 1-21), which is subsequently cleaved off in the mature form. High expression of DKK3 is reported in heart, brain, and spinal cord. DKK3 is shown to antagonize canonical Wnt signaling by inhibiting LRP5/6 interaction with Wnt and by forming a ternary complex with Kremen protein, which is known to promote internalization of LRP5/6. The C-terminal cysteine-rich domain of DKK3 mediates its interaction with LRP5 and LRP6. DKK3 is shown to induce a redistribution of β-catenin to the cell membrane where β-catenin promotes cell-cell adhesion by binding to the cytoplasmic domain of E-cadherin to form adheren junction complex. This binding also prevents nuclear translocation of β-catenin that reduces Wnt-mediated LEF/TCF transactivation. DKK3 is proposed to act as a tumor suppressor protein and its over-expression is shown to suppress tumor growth. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
