Previous GeneCards Identifiers for DKK2 Gene
This gene encodes a protein that is a member of the dickkopf family. The secreted protein contains two cysteine rich regions and is involved in embryonic development through its interactions with the Wnt signaling pathway. It can act as either an agonist or antagonist of Wnt/beta-catenin signaling, depending on the cellular context and the presence of the co-factor kremen 2. Activity of this protein is also modulated by binding to the Wnt co-receptor LDL-receptor related protein 6 (LRP6). [provided by RefSeq, Jul 2008]
GeneCards Summary for DKK2 Gene
DKK2 (Dickkopf WNT Signaling Pathway Inhibitor 2) is a Protein Coding gene. Among its related pathways are Reelin Pathway (Cajal-Retzius cells) and HIV Life Cycle. Gene Ontology (GO) annotations related to this gene include RNA polymerase II transcription factor activity, sequence-specific DNA binding. An important paralog of this gene is DKK1.
UniProtKB/Swiss-Prot for DKK2 Gene
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 (By similarity).
