Summary
RNA molecules move between the nucleus and cytoplasm via specific pathways. Proteins bound to each RNA type provide signals for this essential nucleocytoplasmic transport in eukaryotic cells.
Area of Science:
- Molecular Biology
- Cell Biology
- Genetics
Background:
- RNA molecules are synthesized in the nucleus and must reach specific cellular locations for function.
- Nucleocytoplasmic transport is crucial for gene expression and cellular processes in eukaryotic cells.
- Understanding RNA transport mechanisms is fundamental to cell biology.
Purpose of the Study:
- To review the specific transport pathways for various RNA classes between the nucleus and cytoplasm.
- To highlight the molecular mechanisms governing nucleocytoplasmic RNA transport.
- To emphasize the role of associated proteins in mediating RNA transport.
Main Methods:
- Literature review of recent studies on RNA transport.
- Focus on messenger RNA, small nuclear RNA, ribosomal RNA, and transfer RNA.
- Analysis of molecular mechanisms and protein-RNA interactions.
Main Results:
- Specific transport pathways exist for different RNA classes.
- Nucleocytoplasmic transport relies on distinct signals for each RNA type.
- Proteins associated with RNA largely provide these transport signals.
Conclusions:
- Substantial progress has been made in understanding RNA transport mechanisms.
- Protein-bound signals are key mediators of RNA nucleocytoplasmic transport.
- Further research into these mechanisms will illuminate fundamental cellular processes.

02:22Regulated mRNA Transport
In eukaryotes, transcription and translation are compartmentalized; an mRNA is first synthesized in the nucleus and then selectively transported to the cytoplasm for protein synthesis. Before transport, a pre-mRNA undergoes several steps of post-transcriptional modifications including splicing, 5' capping, and the addition of a poly-adenine tail. Various proteins bind to the pre-mRNA during these modifications. The mRNA transport takes place with the help of multiple proteins playing specific...
01:45Overview of Protein Sorting and Transport
Eukaryotic cells have different membrane-bound organelles with distinct protein requirements. The process by which proteins are targeted to a specific organelle is called protein sorting.
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...

01:42Directionality of Nuclear Transport
Ras-related nuclear protein or Ran is a small G protein that cycles between its GTP and GDP bound states. Ran specific regulators, a Ran GTPase Activating Protein or RanGAP present in the cytosol and a Ran guanine nucleotide exchange factor or RanGEF present inside the nucleus regulate GTP/GDP exchange. A high concentration of GTP inside the cells, in addition to this asymmetric distribution of Ran-specific regulators, leads to a higher RanGTP concentration inside the nucleus. This...
01:20Cotranslational Protein Translocation
Translocation of proteins across membranes is an ancient process that occurs even in bacteria and archaebacteria. In fact, the components of the translocation machinery are still conserved between prokaryotes and eukaryotes.

01:27Post-translational Translocation of Proteins to the RER
A sizable fraction of proteins destined for ER are first synthesized in the cell cytosol and then transported across the ER membrane–a process called post-translational translocation. Similar to cotranslationally translocated proteins, these proteins also use the Sec translocon complex to enter the ER lumen.
Targeting proteins to the ER
Hsp40 and Hsp70 chaperone molecules bind the translated proteins in the cytosol to prevent their folding. The chaperone binding helps to keep the signal...
