DKK-1 Protein, Cynomolgus/Rhesus Macaque (HEK293, Fc)

DKK-1 Proteinas are potent antagonists of canonical Wnt signaling, inhibiting LRP5/6-Wnt interactions and forming a ternary complex with KREMEN to promote LRP5/6 internalization. In addition to its proapoptotic function by antagonizing KREMEN1 independently of Wnt, DKK-1 also exhibits antiapoptotic activity. DKK-1 Protein, Cynomolgus/Rhesus Macaque (HEK293, Fc) is the recombinant Rhesus Macaque-derived DKK-1 protein, expressed by HEK293 , with C-mFc labeled tag.

DKK1 protein functions as a potent antagonist of canonical Wnt signaling through multiple mechanisms. It inhibits the interaction between LRP5/6 and Wnt and forms a ternary complex with the transmembrane protein KREMEN, facilitating the internalization of LRP5/6. Notably, DKK1 not only antagonizes the pro-apoptotic function of KREMEN1 in a Wnt-independent manner but also exhibits anti-apoptotic activity. The protein is implicated in limb development, where it modulates Wnt signaling to ensure normal limb patterning. Through its C-terminal Cys-rich domain, DKK1 interacts with LRP5 and LRP6, specifically engaging with beta-propeller regions 3 and 4 of LRP5. This interaction is further influenced by MESD and/or KREMEN, collectively leading to the attenuation of Wnt-mediated signaling. Additionally, DKK1 forms a ternary complex with LRP6 and KREM1, highlighting its multifaceted role in regulating crucial cellular processes and interactions with key proteins involved in Wnt signaling.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
