SUFU (Suppressor of Fused) was identified in Drosophila as a suppressor of the Fused (Fu) kinase that is essential for Hedgehog signaling during embryonic pattern formation. SUFU suppresses Hedgehog signaling by regulating the localization of the transcription factors Gli and Ci. In Drosophila, SUFU may also positively regulate Hedgehog signaling depending on SUFU protein levels and Hedgehog signal intensity. SUFU may function as a tumor suppressor as inactivation and loss of heterozygosity of SUFU is associated with human rhabdomyosarcomas and medulloblastomas. Deletion of SUFU in mice results in embryonic lethality, while heterozygotes exhibit developmental defects characteristic of basal cell nevus syndrome. This aberrant developmental pathway is attributed to ligand-independent activation of Hedgehog signaling. GSK-3beta binds and phosphorylates SUFU in vitro and additional information predicts that GSK-3beta may positively regulate Hedgehog signaling through modification of SUFU.
