Summary
Nuclear pore complexes (NPCs) and their transport factors are crucial for moving molecules into and out of the nucleus. Emerging research reveals their surprising roles in cell division and chromosome segregation during mitosis.
Area of Science:
- Cell Biology
- Molecular Biology
- Genetics
Background:
- Nuclear pore complexes (NPCs) regulate macromolecule transport between the cytoplasm and nucleus.
- Nuclear transport machinery components facilitate cargo movement and accumulation.
- Established roles in nuclear transport, but emerging links to mitosis.
Purpose of the Study:
- To review the evolving understanding of nuclear transport factors in mitosis.
- To discuss emerging hypotheses on the role of nuclear transport machinery in mitotic progression.
Main Methods:
- Literature review of recent findings.
- Synthesis of observations linking nuclear transport to mitotic processes.
Main Results:
- Growing evidence connects nuclear transport machinery to chromosome segregation.
- Components are implicated in spindle assembly and kinetochore function.
- Involvement in the spindle assembly checkpoint is increasingly recognized.
Conclusions:
- Nuclear transport apparatus components play significant roles in mitotic progression.
- Further research is needed to elucidate these novel functions.
- This highlights a potential new layer of regulation in cell division.

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...
01:34Nuclear Protein Sorting
Nuclear protein sorting is the selective trafficking of histones, polymerases, gene regulatory proteins into the nucleus and exporting RNAs and ribosomes to the cytosol. It is a tightly controlled process that regulates gene expression within a cell.
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...

01:45Regulation of Nuclear Protein Sorting
Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...
02:27The Mitotic Spindle
The mitotic spindle—or spindle apparatus—is a eukaryotic, cytoskeletal structure made up of long protein fibers called microtubules. Formed during cell division, the spindle separates sister chromatids and moves them to opposite ends of a parental cell, where the now individual chromosomes are distributed to two daughter cell nuclei.
The bipolar configuration of the mitotic spindle facilitates chromosomal segregation, preparing the cell for division. One mechanism that ensures bipolar mitotic...

In eukaryotes, the cell division cycle is divided into distinct, coordinated cellular processes that include cell growth, DNA replication/chromosome duplication, chromosome distribution to daughter cells, and finally, cell division. The cell cycle is tightly regulated by its regulatory systems as well as extracellular signals that affect cell proliferation.
The processes of the cell cycle occur over approximately 24 hours (in typical human cells) and in two major distinguishable stages. The...
