SOST Protein, Human (HEK293, His-Avi)

SOST protein acts as a potent inhibitor of bone growth by effectively suppressing Wnt signaling and subsequent bone formation. Through interactions with key Wnt pathway components, including LRP4, LRP5, and LRP6, SOST exerts inhibitory effects. Its interaction with LRP4, mediated by the extracellular domain, suppresses Wnt signaling, while interactions with LRP5, specifically through the first two YWTD-EGF repeat domains, contribute to Wnt-mediated signaling inhibition. These interactions emphasize SOST's crucial role in regulating bone development and maintaining bone homeostasis. SOST Protein, Human (HEK293, His-Avi) is the recombinant human-derived SOST protein, expressed by HEK293, with N-His, N-Avi labeled tag. The total length of SOST Protein, Human (HEK293, His-Avi) is 190 a.a., with molecular weight of 28-40 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.
