Rho 家族 GTP 酶属于 Ras GTP 酶超家族,可转导细胞内信号,已知可调节多种细胞过程,包括细胞极性、形态发生、迁移、细胞凋亡、囊泡运输、病毒运输和细胞转化。三个最具特征的 Rho 家族成员是 Cdc42、RhoA 和 Rac1。 Cdc42 调节内吞作用、内质网和高尔基体之间的运输、高尔基体后运输和胞吐作用。 Cdc42 通过与 Wiskott-Aldrich 综合征蛋白 (N-WASP) 和 Arp2/3 复合体相互作用来影响运输,从而导致肌动蛋白动力学发生变化。 Rac1 通过与其效应器、PI3 激酶、synaptojanin 2、IQGAP1 和磷脂酶 D1 相互作用介导内吞和外吐囊泡运输。 RhoA 通过控制其下游靶标 Rho 激酶参与内吞作用的调节。有趣的是,这些 GTP 酶在受感染宿主细胞中病毒蛋白和基因组运输的不同阶段发挥着重要作用。重要的是,Cdc42、Rac1 和 RhoA 的失调会导致多种疾病,包括恶性转化。在某些情况下,细胞转化需要 Rho GTP 酶的过度激活。在本文中,我们回顾了与 Rho GTP 酶在细胞内转运和细胞转化中的功能相关的一些发现。
Rho family GTPases belong to the Ras GTPase superfamily and transduce intracellular signals known to regulate a variety of cellular processes, including cell polarity, morphogenesis, migration, apoptosis, vesicle trafficking, viral transport and cellular transformation. The three best-characterized Rho family members are Cdc42, RhoA and Rac1. Cdc42 regulates endocytosis, the transport between the endoplasmic reticulum and Golgi apparatus, post-Golgi transport and exocytosis. Cdc42 influences trafficking through interaction with Wiskott-Aldrich syndrome protein (N-WASP) and the Arp2/3 complex, leading to changes in actin dynamics. Rac1 mediates endocytic and exocytic vesicle trafficking by interaction with its effectors, PI3kinase, synaptojanin 2, IQGAP1 and phospholipase D1. RhoA participates in the regulation of endocytosis through controlling its downstream target, Rho kinase. Interestingly, these GTPases play important roles at different stages of viral protein and genome transport in infected host cells. Importantly, dysregulation of Cdc42, Rac1 and RhoA leads to numerous disorders, including malignant transformation. In some cases, hyperactivation of Rho GTPases is required for cellular transformation. In this article, we review a number of findings related to Rho GTPase function in intracellular transport and cellular transformation.
