Description

20(S)-hydroxyCholesterol (20α-Hydroxycholesterol) is an allosteric activator of the oncoprotein smoothened (Smo) that activates the hedgehog (Hh) signaling pathway with an EC50 of 3 μM in a gene transcription reporter assay using NIH3T3 cells[1][2].


20-hydroxycholesterol is an oxysterol that is cholesterol substituted by a hydroxy group at position 20. It has a role as a human metabolite and a mouse metabolite. It is a 20-hydroxy steroid, an oxysterol and a 3beta-hydroxy-Delta(5)-steroid.
