Cholesterol 67-78 7-dehydrocholesterol reductase Homo sapiens 90-95 16687448-5 2006 DHCR7 has previously been implicated to function as a positive regulator of Hh signaling that acts to regulate the cholesterol adduction of Hh ligand or to affect Hh signaling in the responding cell. Cholesterol 115-126 7-dehydrocholesterol reductase Homo sapiens 0-5 16687448-7 2006 Our analysis also raises the possibility that the human condition SLOS is caused not only by disruption of the enzymatic role of DHCR7 as a reductase in cholesterol biosynthesis, but may also involve defects in DHCR7 resulting in derepression of Shh signaling.
