迄今为止,大多数关于Rho GT3调节的研究都集中在经典的GT3循环- GTP结合和水解-由鸟嘌呤核苷酸交换因子(GEF)、GTP酶激活蛋白(GAP)和GDP解离抑制剂(GDI)控制。最近的研究已经揭示了重要的其他调节机制:microRNA(miRNA)调节Rho GTP酶编码mRNA的转录后加工;棕榈酰化和核靶向影响细胞内分布;翻译后磷酸化,转谷氨酰胺化和AMP化影响Rho GTP酶信号传导;和泛素化控制Rho GTP酶蛋白的稳定性和周转。这些调节模式增加了Rho GTP酶信号传导网络的复杂性,并允许对单个Rho GTP酶进行精确的时空控制。本次审查将讨论这些“非常规”的调控模式和它们对细胞功能的贡献,重点是转录后和翻译后事件超越经典的GTdR循环调控模型。
To date, most studies of Rho GTPase regulation have focused on the classic GTPase cycle – GTP binding and hydrolysis – controlled by guanine nucleotide exchange factors (GEFs), GTPase-activating proteins (GAPs) and GDP-dissociation inhibitors (GDIs). Recent investigations have unveiled important additional regulatory mechanisms: microRNA (miRNA) regulating post-transcriptional processing of Rho GTPase-encoding mRNAs; palmitoylation and nuclear targeting affecting intracellular distribution; post-translational phosphorylation, transglutamination and AMPylation impacting Rho GTPase signaling; and ubiquitination controlling Rho GTPase protein stability and turnover. These modes of regulation add to the complexity of the Rho GTPase signaling network and allow precise spatiotemporal control of individual Rho GTPases. This review will discuss these ‘unconventional’ modes of regulation and their contribution to cellular function, focusing on post-transcriptional and post-translational events beyond the classic GTPase cycle regulatory model.
