DKK1 Protein, Human (HEK293, His-Avi)

DKK-1 Proteinas, a potent antagonist of canonical Wnt signaling, inhibits LRP5/6-Wnt interaction and forms a ternary complex with KREMEN, facilitating LRP5/6 internalization. Beyond antagonizing KREMEN1's pro-apoptotic function independently of Wnt, DKK-1 exhibits anti-apoptotic activity. Implicated in limb development, it modulates Wnt signaling for normal limb patterning. Interacting with LRP5/6 through its C-terminal Cys-rich domain, DKK-1 attenuates Wnt-mediated signaling influenced by MESD and/or KREMEN, emphasizing its multifaceted role in regulating cellular processes. DKK1 Protein, Human (HEK293, His-Avi) is the recombinant human-derived DKK1 protein, expressed by HEK293, with C-Avi, C-His labeled tag. The total length of DKK1 Protein, Human (HEK293, His-Avi) is 235 a.a., with molecular weight of 45-55 kDa.

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.
