| Product Name | Human Dickkopf-related protein 4 (DKK4) ELISA Kit |
|---|---|
| Description | All DKKs have several potential sites for cleavage by furin-type proteases. Northern blot analysis detected no expression of DKK4, but RT-PCR analysis detected DKK4 expression in cerebellum, T-cell, esophagus, and lung cDNA libraries. Western blot analysis showed that DKK4 is secreted as 40-, 30- to 32-, and 15- to 17-kD proteins; these proteins were not significantly affected by N-glycanase treatment. N-terminal sequence analysis of the different forms suggested that DKK4 is proteolytically processed, possibly by intracellular furin-type proteases. Functional analysis determined that DKK4 blocks Xenopus Wnt8, Wnt3a, and Wnt2b, but not Dsh or Fz8, induction of a secondary axis in frog embryos, indicating that DKKs antagonize WNT function upstream of WNT receptors. This assay has high sensitivity and excellent specificity for detection of Human DKK4. No significant cross-reactivity or interference between Human DKK4 and analogues was observed. |
