Insights

Anticancer drugs targeting microtubules alter cell dynamics. This review explores how tubulin folding, not just mass, influences microtubule dynamics and disease, offering new therapeutic insights.

Area of Science:

  • Cell Biology
  • Biochemistry
  • Pharmacology

Background:

  • Microtubules are crucial for cell functions and are targeted by anticancer drugs like taxanes and vinca-alkaloids.
  • Antitubulin agents primarily affect microtubule dynamics rather than mass at therapeutic concentrations.
  • Microtubule-associated proteins regulate dynamics, but tubulin folding is emerging as a key factor.

Purpose of the Study:

  • To review current knowledge on tubulin folding pathways.
  • To examine the relationship between tubulin folding and diseases.
  • To explore the potential influence of tubulin folding on microtubule dynamics.

Main Methods:

  • Literature review of studies on tubulin folding.
  • Analysis of data linking tubulin folding to disease.
  • Synthesis of information on tubulin folding's role in microtubule dynamics.

Main Results:

  • Tubulin folding pathways are critical for microtubule function.
  • Dysfunctional tubulin folding is associated with various diseases.
  • Tubulin folding significantly impacts microtubule dynamics, complementing the role of associated proteins.

Conclusions:

  • Tubulin folding is a vital, underappreciated regulator of microtubule dynamics.
  • Understanding tubulin folding offers potential for novel anticancer strategies.
  • Further research into tubulin folding pathways could reveal new therapeutic targets.

Microtubule 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...

Microtubule Formation

Microtubules are dynamic structures that undergo continuous assembly and disassembly. They originate from specialized multi-protein complexes known as microtubule organizing centers or MTOCs. Within the MTOC, the point of origin of the microtubule is known as the minus end, while the end radiating outward is the plus end. Microtubules serve two primary functions — the organization of spindle complexes to separate sister chromatids during mitotic or meiotic cell division and the formation of...

Destabilization 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...

Microtubules

Microtubules are the thickest cytoskeletal filaments with a diameter of 25 nm. In prokaryotic organisms, microtubules are commonly found in locomotory appendages like cilia and flagella. In eukaryotic cells, microtubules form specialized extensions for moving fluid over the surface, like those found in cells lining the intestine.
Microtubules have two structurally similar globular protein subunits: α and β tubulins. In the cytosol, the α and β tubulins form a heterodimer. These αβ-heterodimers...

Microtubules

There are three types of cytoskeletal structures in eukaryotic cells—microfilaments, intermediate filaments, and microtubules. With a diameter of about 25 nm, microtubules are the thickest of these fibers. Microtubules carry out a variety of functions that include cell structure and support, transport of organelles, cell motility (movement), and the separation of chromosomes during cell division.Microtubules are hollow tubes whose walls are made up of globular tubulin proteins. Each tubulin...
