受体酪氨酸激酶(RTK)根据其胞外成分(或“胞外结构域”)的结构可分为20类。RTK胞外结构域在结构上是模块化的,包括从15个不同的折叠拓扑中提取的结构域。我们在这里介绍这个丰富的领域架构的概述,为后续章节提供结构生物学参考材料。此外,我们描述了与RTK胞外域结合的配体的结构生物学以及随后的信号转导性质在RTK超家族中是如何变化的-特别是,识别出四种不同的受体激活模式。然而,这个非常广泛的受体家族的大部分分子细节仍然只有部分了解。
The receptor tyrosine kinases (RTKs) can be classified in twenty classes on the basis of the structural architecture of their extracellular components (or “ectodomains”). RTK ectodomains are modular in structure and comprise domains drawn from fifteen distinct fold topologies. We present here an overview of this rich domain architecture to provide structural biology reference material for the ensuing chapters. In addition, we describe how the structural biology of ligand binding to the RTK ectodomain and the subsequent nature of signal transduction vary across the RTK superfamily – in particular, four distinct modes of receptor activation are discerned. However, much of the molecular detail of this remarkably broad family of receptors remains only partially understood.
