Direct ELISA showing purified anti-human DKK-1 (clone W19277H) bound to plate-immobilized recombinant human DKK-1 protein (Cat. Nos. 778602, 778604, and 778606). The wells were incubated with serially diluted primary antibody at room temperature for 2 hours in 1% BSA-PBS, followed by incubation with HRP goat anti-rat IgG (Cat. No. 405405). TMB substrate (Cat. No. 421501) was used for detection. Absorbance was measured at 450 nm.

DKK-1 (Dickkopf related protein 1) is a member of the Dickkopf family of proteins that include DKK-1, -2, -3, -4, and Soggy. DKK-1 was discovered by its ability to block Wnt signaling during early Xenopus embryogenesis. DKK-1 antagonizes canonical Wnt signaling by inhibiting LRP5/6 interaction with Wnt proteins. DKK-1 forms a ternary complex with LRP5/6 and the transmembrane protein Kremen1/2, promoting internalization of LRP5/6 and down regulation of Wnt signaling. DKK-1 contains two conserved cysteine-rich domains separated by a linker region. The N-terminal cysteine-rich domain is unique to DKKs while the C-terminal cysteine-rich domain has a pattern of 10 cysteines similar to colipase. DKK-1 binds with LRP6 with high affinity and this interaction is enhanced by Kremens. The interactions between DKK-1 and both LRP6 and Kremens are mediated via C-terminal cysteine-rich domain. DKKs are expressed throughout development and play an important role by locally inhibiting Wnt regulated processes such as limb development, somitogenesis, anteroposterior axial patterning, and eye formation. In adults, DKKs are implicated in bone formation and bone disease, cancer and Alzheimer's disease. The balance between Wnt signaling and DKK-1 inhibition is important for bone homeostasis. Increased expression of DKK-1 are found in lung cancers, esophageal squamous cell carcinomas, and hormone-resistant breast cancers. DKK-1 expression is decreased in malignant melanoma and colorectal cancers.
