项目摘要
G proteins, which cycle between the two different GTP- and GDP-bound conformations, play important roles as a "molecular switch" in many intracellular signaling pathways. The G protein families include the translation factors, the trimeric G proteins, and the small GTPases. Although the small GTPases are involved in the regulation of cell growth/differentiation, vesicle trafficking, and cell shape/adhesion, there are still many other GTPases, of which functions are unknown. In the Scientific Research on Priority Areas "G-protein signal", we investigated novel GTPases exhibiting unique biochemical and/or structural properties different from typical small GTPases and found that the atypical G proteins play important roles in lysosome biogenesis, cilia formation, and recycling-endosome dynamics. Thus, our findings contributed much toward an understanding of the novel functions of G proteins.
G 蛋白在两种不同的 GTP 和 GDP 结合构象之间循环,在许多细胞内信号传导途径中作为“分子开关”发挥着重要作用。 G 蛋白家族包括翻译因子、三聚体 G 蛋白和小 GTP 酶。尽管小 GTP 酶参与细胞生长/分化、囊泡运输和细胞形状/粘附的调节,但仍有许多其他 GTP 酶,其功能尚不清楚。在优先领域“G蛋白信号”科学研究中,我们研究了具有不同于典型小GTP酶的独特生化和/或结构特性的新型GTP酶,发现非典型G蛋白在溶酶体生物合成、纤毛形成和回收中发挥重要作用-内体动力学。因此,我们的发现对理解 G 蛋白的新功能做出了很大贡献。
