细胞生物学中的许多基本过程都受Rho GTP酶的调控,包括细胞的黏附、迁移和分化。在调节细胞功能的同时,Rho蛋白家族的成员相互合作或相互对抗。由此产生的分子网络显示出在时间和空间上动态调节的多个级别的相互作用。在本综述的第一部分,我们描述了这种串扰的主要机制,它可以发生在三个不同的途径水平:(1)通过调节活性,(2)通过调节蛋白质的表达和稳定性,以及(3)通过调节下游信号通路。在第二部分中,我们通过两个例子来说明Rho蛋白串扰的重要性:基于整合素的黏附和细胞迁移。
Many fundamental processes in cell biology are regulated by Rho GTPases, including cell adhesion, migration and differentiation. While regulating cellular functions, members of the Rho protein family cooperate or antagonize each other. The resulting molecular network exhibits many levels of interaction dynamically regulated in time and space. In the first part of this review, we describe the main mechanisms of this crosstalk, which can occur at three different levels of the pathway: (1) through regulation of activity, (2) through regulation of protein expression and stability, and (3) through regulation of downstream signaling pathways. In the second part, we illustrate the importance of Rho protein crosstalk with two examples: integrin-based adhesion and cell migration.
