See IHC antigen retrieval protocols.

1/250.00000 - 1/500.00000
  • Application notes
    Is unsuitable for Flow Cyt or ICC/IF.

    • Target

    • Function

      Antagonizes canonical Wnt signaling by inhibiting LRP5/6 interaction with Wnt and by forming a ternary complex with the transmembrane protein KREMEN that promotes internalization of LRP5/6. DKKs play an important role in vertebrate development, where they locally inhibit Wnt regulated processes such as antero-posterior axial patterning, limb development, somitogenesis and eye formation. In the adult, Dkks are implicated in bone formation and bone disease, cancer and Alzheimer disease.

    • Tissue specificity

      Placenta.

    • Sequence similarities

      Belongs to the dickkopf family.

    • Domain

      The C-terminal cysteine-rich domain mediates interaction with LRP5 and LRP6.

    • Cellular localization

        The smear bands detected by ab109416 are similar to those reported by the papers (PMID: 18546262, 28090290, 24008318), which should be due to the glycosylation of DKK1.
