Toward the atomic structure of the nuclear pore complex: when top down meets bottom up.


ABSTRACT: Elucidating the structure of the nuclear pore complex (NPC) is a prerequisite for understanding the molecular mechanism of nucleocytoplasmic transport. However, owing to its 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, thereby bridging the resolution gap from the higher-order scaffold structure to near-atomic resolution and opening the door for structure-guided experimental interrogations of NPC function.
