Transport of nucleic acids through membrane channels: snaking through small holes
1Department of Biochemistry and Cell Biology, State University of New York, Stony Brook 11794.
Abstract:
Transport of nucleic acids through cell membranes is an essential biological process that occurs in all living organisms. This review focuses on two plant systems in which nucleic acid molecules are transported through membrane channels: transport of Agrobacterium T-DNA through nuclear pores and movement of plant viruses through intracellular connections. To provide a broader perspective, nuclear uptake of animal viruses and nuclear import/export of small nuclear (sn) RNA and messenger (m) RNA are described. By comparing the examined cases of nucleic acid transport, the review proposes a set of general rules for this type of transport through membrane channels.

Transporters facilitate either an active or passive movement of solutes. They can allow a single-molecule transport down its...
Overview of Protein Sorting and Transport
Protein sorting can be of two types: signal-based sorting and vesicle-based trafficking. In signal-based sorting, specific amino acid sequences called sorting signals target proteins to the proper location inside the cell either via gated transport or by protein translocation. In gated transport, folded...
Nuclear Protein Sorting
Proteins targeted to the nucleus carry nuclear localization signals or NLS recognized by import receptors in the cytosol. Similarly, proteins with nuclear export signals are recognized by export receptors. Import and export receptors are...
Introduction to Membrane Traffic
The transport of soluble and membrane proteins is mediated by transport vesicles that collect cargo from one cellular compartment and deliver it to another by fusing with the target organelle membrane. The Rab...
