Q2M1P5

功能描述

对hedgehog信号通路调控至关重要:作为sonic hedgehog (Shh)和Indian hedgehog (Ihh)通路的负调控因子和正调控因子,在SMO下游通过SUFU依赖和非依赖机制发挥作用 (PubMed:21633164)。参与微管动力学调控。为纤毛顶端的正确组织和SUFU-GLI2复合物的纤毛定位控制所必需 (By similarity)。为响应Shh时GLI3定位于纤毛所必需。通过阻止配体缺失时转录激活因子GLI2的不当激活,负调控Shh信号通路。通过阻止转录因子GLI3加工为其抑制形式,正调控Shh信号通路。在角质形成细胞中,促进SUFU-GLI2复合物解离、GLI2核易位及Shh信号通路激活 (By similarity)。参与表皮分化及软骨细胞发育调控 (By similarity)。 {ECO:0000250|UniProtKB:B7ZNG0, ECO:0000269|PubMed:21633164}。
