SOST Protein, Human (Biotinylated, HEK293, His, Avi)

SOST proteins act as potent inhibitors of bone growth by effectively inhibiting Wnt signaling and subsequent bone formation. SOST exerts its inhibitory effect by interacting with key Wnt pathway components, including LRP4, LRP5, and LRP6. SOST Protein, Human (Biotinylated, HEK293, His, Avi) is the recombinant human-derived SOST protein, expressed by HEK293 , with C-Avi, N-10*His labeled tag. The total length of SOST Protein, Human (Biotinylated, HEK293, His, Avi) is 190 a.a., with molecular weight of Monomer:33 kDa; Dimer:66 kDa.

SOST protein serves as a potent negative regulator of bone growth by effectively inhibiting Wnt signaling and subsequent bone formation. Through interactions with key components of the Wnt pathway, including LRP4, LRP5, and LRP6, SOST exerts its inhibitory influence. Notably, its interaction with LRP4, mediated via the extracellular domain, facilitates the suppression of Wnt signaling, while interactions with LRP5, specifically through the first two YWTD-EGF repeat domains, contribute to the inhibition of Wnt-mediated signaling. These molecular interactions underscore the crucial role of SOST in modulating the intricate signaling cascades that govern bone development, providing essential regulatory mechanisms to maintain bone homeostasis.

Immobilized Human LRP-6 mFc at 5 μg/mL (100 μL/well) can bind Biotinylated Human SOST His with a linear range of 0.005-2.089 μg/mL.
