The Hedgehog (Hh) proteins play a universal role in metazoan development. Nevertheless, fundamental differences exist between Drosophila and vertebrates in the transduction of the Hh signal, notably regarding the role of primary cilia in mammalian cells. In this issue of Genes & Development, Chen and colleagues (pp. 1910-1928) demonstrate that mouse Suppressor of fused (Sufu) regulates the stability of the transcription factors Gli2 and Gli3 by antagonizing the conserved Gli degradation device mediated by Hib/Spop in a cilia-independent manner.
刺猬(Hh)蛋白在多细胞动物发育中发挥着普遍作用。然而,果蝇和脊椎动物在Hh信号转导方面存在根本差异,特别是在初级纤毛在哺乳动物细胞中的作用方面。在本期《基因与发育》中,陈及其同事(第1910 - 1928页)证明,小鼠融合抑制因子(Sufu)通过以不依赖纤毛的方式拮抗由Hib/Spop介导的保守Gli降解机制,来调节转录因子Gli2和Gli3的稳定性。
