- SynonymDKK3,REIC,RIG
- SourceHuman Dkk-3 (R335G), His Tag (DK3-H5220) is expressed from human 293 cells (HEK293). It contains AA Ala 22 - Ile 350 (Accession # Q9UBP4-1(R335G)).Predicted N-terminus: Ala 22Request for sequence
- Molecular Characterization
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 37.0 kDa. The protein migrates as 45-65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>95% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

- BackgroundMembers of the dickkopf-related protein family (DKK-1, -2, -3, and -4) are secreted proteins with two cysteine-rich domains separated by a linker region. And DKK3 has been proposed as tumour suppressor gene and a marker for tumour blood vessels. DKK3 is the only DKK family member abundantly expressed in normal lung, but silenced by promoter hypermethylation in a large fraction of lung cancer cell lines and lung tumors. Downregulation of DKK3 was correlated with tumor progression and expression of nuclear beta-catenin in lung tumors. Ectopic expression of DKK3 in lung cancer cells with DKK3 hypermethylation induced apoptosis and inhibited TCF-4 activity as well as nuclear accumulation of beta-catenin and expression of TCF-4 targets c-Myc and cyclin D1. DKK3 modulates FGF and Activin/Nodal signaling to regulate mesoderm induction during early Xenopus development, was reported.
