Biological Activity

Allosteric activator of the Hedgehog signaling pathway Smoothened (Smo) oncoprotein; binds at a site distinct from the canonical cyclopamine binding site. Activates Hedgehog (Hh) signaling (EC50 ~ 3μM for induction of Hh reporter gene transcription in in NIH 3T3 cells). Induces Smo accumulation in primary cilia; also exhibits osteogenic activity and activates the liver X receptor (LXR).
