RAS蛋白是从细胞表面受体发出的信号通路的重要组成部分。由于错义突变导致的这些蛋白质的致癌性激活在几种类型的癌症中经常被检测到。大量的生物化学和遗传学研究表明,RAS蛋白控制着一个复杂的分子回路,该回路由一系列相互连接的途径组成。在这篇综述中,我们描述了RAS癌基因如何利用其广泛的信号传导范围来影响驱动肿瘤发生的多个细胞过程。
RAS proteins are essential components of signalling pathways that emanate from cell surface receptors. Oncogenic activation of these proteins owing to missense mutations is frequently detected in several types of cancer. A wealth of biochemical and genetic studies indicates that RAS proteins control a complex molecular circuitry that consists of a wide array of interconnecting pathways. In this Review, we describe how RAS oncogenes exploit their extensive signalling reach to affect multiple cellular processes that drive tumorigenesis.
