Dynamic nuclear pore complexes: life on the edge.


PMID 16777596

Abstract

The exchange of molecules between the nucleus and cytoplasm is mediated through nuclear pore complexes (NPCs) embedded in the nuclear envelope. Altering the interactions between transport receptors and their cargo has been shown to be a major regulatory mechanism to control traffic through NPCs. New evidence now suggests that NPC proteins play active roles in translocation, and that transport is also controlled by dynamic changes in NPC composition and architecture. This view of ever-changing NPCs necessitates the re-evaluation of current models of nuclear transport and how this process is regulated.
