阐明核孔复合物(NPC)的结构是理解核质转运分子机制的前提。然而,由于庞大的规模和灵活性,NPC是不可接近的经典结构测定技术,需要互补的方法的共同努力。而自下而上的方法依赖于生化相互作用的研究和NPC成分的晶体结构测定,自上而下的方法试图确定原位完整的NPC的结构。最近,这两种方法已经融合,弥合了从高阶支架结构到近原子分辨率的分辨率差距,并为NPC功能的结构引导实验询问打开了大门。
Elucidating the structure of the nuclear pore complex (NPC) is a prerequisite for understanding the molecular mechanism of nucleocytoplasmic transport. However, due to sheer size and flexibility, the NPC is unapproachable by classical structure determination techniques and requires a joint effort of complementary methods. Whereas bottom up approaches rely on biochemical interaction studies and crystal structure determination of NPC components, top down approaches attempt to determine the structure of the intact NPC in situ. Recently, both approaches have converged, bridging the resolution gap from higher-order scaffold structure to near-atomic resolution and opening the door for structure-guided experimental interrogations of NPC function.
