Summary
Nuclear pore complexes (NPCs) regulate transport between the nucleus and cytoplasm. Recent studies reveal NPCs as dynamic, modular machines, advancing our understanding of their complex molecular architecture.
Area of Science:
- Cell biology
- Molecular biology
- Structural biology
Background:
- Nuclear pore complexes (NPCs) are essential gateways for nucleocytoplasmic transport.
