Physics of the Nuclear Pore Complex: Theory, Modeling and Experiment

Area of Science:

• Cell Biology
• Biophysics
• Nanoscience

Background:

• Eukaryotic cells feature a nucleus enclosed by the nuclear envelope (NE), necessitating transport of molecules across it.
• The Nuclear Pore Complex (NPC) acts as a nanomachine controlling this bi-directional transport, ensuring cellular function.
• NPCs exhibit high specificity, speed, and robustness, with conserved mechanisms across eukaryotes.

Purpose of the Study:

• To review the physical understanding of Nuclear Pore Complex (NPC) architecture and function.
• To critically analyze experimental studies of NPCs in cells and artificial mimics using theoretical and computational models.
• To discuss connections between NPC operation principles and broader biophysics/bionanotechnology.

Main Methods:

• Analysis of experimental data from molecular cell biology and biophysics.
• Utilizing theoretical and computational modeling approaches.
• Examining artificial NPC mimics with reduced complexity.

Main Results:

• NPC function can be largely explained by fundamental physical concepts.
• Experimental studies and computational models provide insights into NPC architecture and transport mechanisms.
• Artificial NPC mimics recapitulate key aspects of biological pore function.

Conclusions:

• The physical principles governing NPC operation are conserved and understandable.
• Interdisciplinary approaches combining biology, physics, and modeling are crucial for understanding NPCs.
• NPCs offer insights into fundamental biophysical processes and bionanotechnology applications.
