Cholesterylation
WebDec 1, 2024 · Cholesterol modification, or cholesterylation of SMO is a recently defined mechanism to activate SMO. Cholesterol covalently conjugates to the side chain carboxyl of Asp95 (D95) through an ester bond. D95N mutation of SMO, which abolishes cholesterylation, fails to translocate to primary cilia and transduces Hh signaling. WebApr 14, 2011 · Abstract. We report the first chemical probe for bioorthogonal chemical tagging of post-translationally cholesterylated proteins with an azide in living cells. This enables rapid multiplexed fluorescence detection and affinity labelling of protein cholesterylation, as exemplified by Sonic hedgehog protein, opening up new …
