经典钙粘附素是细胞间紧密连接的主要黏附蛋白,是形态发生和组织动态平衡所必需的蛋白质。由于钙粘附素粘附性的亚型差异是钙粘附素功能的核心,一些结构和生物物理方法已经被用来阐明钙粘附素结构、钙粘附素键的生物物理性质和钙粘附素依赖的细胞功能之间的关系。一些实验方法似乎对钙粘附素结合机制提供了相互矛盾的观点。然而,最近的结构和生物物理数据,以及计算机模拟,对经典钙粘素结合产生了新的见解,越来越符合不同的实验结果。这篇综述总结了这些最新的发现,并强调了生成与所有可用实验数据一致的钙粘素相互作用的全面模型所需的一致性和剩余挑战。
Classical cadherins are the principle adhesive proteins at cohesive intercellular junctions, and are essential proteins for morphogenesis and tissue homeostasis. Because subtype-dependent differences in cadherin adhesion are at the heart of cadherin functions, several structural and biophysical approaches have been used to elucidate relationships between cadherin structures, biophysical properties of cadherin bonds, and cadherin-dependent cell functions. Some experimental approaches appeared to provide conflicting views of the cadherin binding mechanism. However, recent structural and biophysical data, as well as computer simulations generated new insights into classical cadherin binding that increasingly reconcile diverse experimental findings. This review summarizes these recent findings, and highlights both the consistencies and remaining challenges needed to generate a comprehensive model of cadherin interactions that is consistent with all available experimental data.
