Insights

Filamentous fungi like Aspergillus nidulans and Ustilago maydis are excellent models for studying cellular transport. Their similarities to metazoan neurons make them suitable for investigating neuropathologies linked to transport defects.

Area of Science:

  • Cell Biology
  • Neuroscience
  • Mycology

Background:

  • Microtubule-based transport is crucial for cellular function and implicated in neuropathologies.
  • Filamentous fungi offer genetic tractability and conserved transport mechanisms relevant to metazoan systems.

Purpose of the Study:

  • To highlight the utility of Aspergillus nidulans and Ustilago maydis as model organisms for studying microtubule-based transport.
  • To explore the relevance of fungal transport systems to human neuropathologies.

Main Methods:

  • Comparative analysis of microtubule-based transport mechanisms in filamentous fungi and metazoan neurons.
  • Leveraging the genetic and biochemical tractability of Aspergillus nidulans and Ustilago maydis.

Main Results:

  • Microtubule-based transport in fungi involves diverse cargos including endosomes, mRNA, and vesicles, mirroring metazoan systems.
  • Similarities in transport mechanisms between fungi and metazoan neurons are evident.

Conclusions:

  • Aspergillus nidulans and Ustilago maydis are suitable models for investigating the molecular basis of transport-related neuropathologies.
  • These fungal models can advance our understanding of diseases such as lissencephaly and motor neuron disease.

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

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...

Microtubule Associated Motor Proteins

Eukaryotic cells have different motor proteins for transporting various cargo within the cell. These motor proteins differ based on the filament they associate with, the direction they move within the cell, and the type of cargo they transport. Motor proteins that associate with microtubules are known as microtubule-associated motor proteins. There are two families of microtubule-associated motor proteins —Kinesins and Dyneins. Both these proteins assist in the transport of cellular cargos...

The Movement of Organelles and Vesicles

In eukaryotic cells,  cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...
Microtubule Formation01:23

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...

Microtubules in Cell Motility

Microtubules are thick hollow cylindrical proteins that help form the cytoskeleton. Microtubules have varied roles in the cell. These filaments help form cellular appendages like cilia and flagella, which are responsible for locomotion. The cilia arise from basal bodies, separated from the main body by a membrane-like structure forming the transition zone. This zone is the gate for the entry of lipids and proteins, creating a unique composition of lipids and proteins in the ciliary membrane and...
