结构研究提供了重要的新的见解如何配体结合促进同源二聚化和激活的EGF受体和其他成员的ErbB家族或受体酪氨酸激酶。这些结构也为ErbB2的独特性质提供了可能的解释,ErbB2没有已知的配体,可以通过简单的过度表达引起细胞转化(和肿瘤发生)。在这些进展的同时,对细胞表面EGF受体的研究越来越多地认为,结构研究缺少关键的机制组件。这是特别明显的结构预测,EGF结合连接到受体二聚化应该是积极的合作,而细胞表面EGF结合的研究表明负协同性。在这篇综述中,我总结了ErbB受体的细胞外区域的解决方案和完整的受体在细胞表面的研究,并试图调和这两种方法所提出的差异。通过结合受体“部分”获得的结果,可以定性地解释整个受体的性质的一些模型。这些考虑强调了将完整的ErbB受体视为完整的变构调节酶的必要性,并将联合收割机的细胞和结构研究结合到一个完整的画面中。
Structural studies have provided important new insights into how ligand binding promotes homodimerization and activation of the EGF receptor and the other members of the ErbB family or receptor tyrosine kinases. These structures have also suggested possible explanations for the unique properties of ErbB2, which has no known ligand and can cause cell transformation (and tumorigenesis) by simple overexpression. In parallel with these advances, studies of the EGF receptor at the cell surface increasingly argue that the structural studies are missing key mechanistic components. This is particularly evident in the structural prediction that EGF binding linked to receptor dimerization should be positively cooperative, whereas cell-surface EGF-binding studies suggest negative cooperativity. In this review, I summarize studies of ErbB receptor extracellular regions in solution and of intact receptors at the cell surface, and attempt to reconcile the differences suggested by the two approaches. By combining results obtained with receptor ‘parts’, it is qualitatively possible to explain some models for the properties of the whole receptor. These considerations underline the need to consider the intact ErbB receptors as intact allosterically regulated enzymes, and to combine cellular and structural studies into a complete picture.
