Previous GeneCards Identifiers for DKK1 Gene
This gene encodes a member of the dickkopf family of proteins. Members of this family are secreted proteins characterized by two cysteine-rich domains that mediate protein-protein interactions. The encoded protein binds to the LRP6 co-receptor and inhibits beta-catenin-dependent Wnt signaling. This gene plays a role in embryonic development and may be important in bone formation in adults. Elevated expression of this gene has been observed in numerous human cancers and this protein may promote proliferation, invasion and growth in cancer cell lines. [provided by RefSeq, Sep 2017]
GeneCards Summary for DKK1 Gene
DKK1 (Dickkopf WNT Signaling Pathway Inhibitor 1) is a Protein Coding gene. Diseases associated with DKK1 include Chiari Malformation Type I and Osteoporosis, Juvenile. Among its related pathways are Primary Focal Segmental Glomerulosclerosis FSGS and Mesodermal Commitment Pathway. Gene Ontology (GO) annotations related to this gene include signal transducer activity and low-density lipoprotein particle receptor binding. An important paralog of this gene is DKK2.
UniProtKB/Swiss-Prot for DKK1 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 (PubMed:22000856). 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 (PubMed:17143291). Inhibits the pro-apoptotic function of KREMEN1 in a Wnt-independent manner, and has anti-apoptotic activity (By similarity).
