Summary
Microtubule (MT) dynamics are crucial for cell functions. This review explores proteins that regulate MT dynamic instability, impacting cell division and migration.
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- Microtubule (MT) dynamics are vital for essential cellular processes like chromosome segregation, cell migration, and differentiation.
- A complex network of intracellular factors regulates MT assembly and disassembly in a spatiotemporally controlled manner, linked to the cell cycle and differentiation.
- Understanding how individual proteins influence MT structure is crucial, though the concerted action of MT stabilizers and destabilizers is still being elucidated.
Purpose of the Study:
- To review the current knowledge on proteins that modulate MT dynamic instability.
- To provide insights into how these proteins affect MT structure and cellular functions.
Main Methods:
- Literature review of scientific articles and research papers.
- Synthesis of existing data on proteins affecting microtubule dynamics.
- Analysis of the interplay between different regulatory factors.
Main Results:
- Identified key proteins that act as stabilizers or destabilizers of MTs.
- Highlighted the intricate regulatory network governing MT dynamics.
- Emphasized the emerging understanding of how individual factors contribute to MT structure.
Conclusions:
- Proper regulation of MT dynamic instability by specific proteins is essential for cellular viability and function.
- Further research into these regulatory proteins will enhance our understanding of cell biology.
- The review consolidates current knowledge, providing a foundation for future investigations into MT-associated disorders.

02:17Microtubule Instability
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated assembly and...

01:45Destabilization of Microtubules
The destabilization of microtubules can occur during different stages of the microtubule lifecycle, such as nucleation or elongation. It can take place at either end of the microtubule or in the microtubule lattices as a whole. The lifespan of individual microtubules within a cell varies according to the cell type and stage of the cell cycle. During interphase, the lifespan of the microtubule is about 30 minutes, while during cell division, it is about 15 minutes. In axonal microtubules of...
01:10Drugs that Destabilize Microtubules
Microtubules are dynamic structures and can be regulated by microtubule targeting agents (MTAs). Microtubule destabilizing drugs are a class of MTAs that destabilize and prevent microtubules' polymerization. Both natural and synthetic chemicals can be found under this class of drugs. Vincristine and vinblastine, two vinca alkaloids, and colchicine were among the first to be discovered. These drugs can affect cells in various ways, either by inducing a change in cell morphology, preventing...
01:15Drugs that Stabilize Microtubules
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...
01:42Microtubule Associated Proteins (MAPs)
Microtubule function and architecture are regulated by an array of specialized proteins called microtubule-associated proteins or MAPs. These proteins are widespread across different organisms and have conserved protein motifs, like the multi-TOG domain for tubulin binding found in the CLASP family of MAPs. Some MAPs are lineage-specific based on their conserved domains. Their functions depend upon the cytoskeletal architecture and cell type they are located within. In-plant cells, a specific...
