RT Journal Article SR Electronic T1 How does cholesterol affect the way Hedgehog works? JF Development JO Development FD The Company of Biologists Limited SP 3055 OP 3061 DO 10.1242/dev.02472 VO 133 IS 16 A1 Wendler, Franz A1 Franch-Marro, Xavier A1 Vincent, Jean-Paul YR 2006 UL http://dev.biologists.org/content/133/16/3055.abstract AB Members of the Hedgehog (Hh) family of proteins are conserved morphogens that spread and modulate cell fates in target tissue. Mature Hh carries two lipid adducts, a palmitoyl group at the N terminus and cholesterol at the C terminus. Recent findings have addressed how these lipid modifications affect the function and transport of Hh in Drosophila. In contrast to the palmitoyl adduct, cholesterol appears not to be essential for signalling. However, the absence of the cholesterol adduct affects the spread of Hh within tissues. As we discuss here, the exact nature of this effect is controversial.
