Summary
Ciliobrevins, novel small molecule inhibitors, offer a rapid method to study dynein motor protein functions in neurons and other cells. These tools provide new insights into cellular processes, complementing traditional research approaches.
Area of Science:
- Cell Biology
- Molecular Neuroscience
- Biochemistry
Background:
- Dyneins are microtubule-based motor proteins crucial for intracellular transport, organelle distribution, and cellular motility like cilia beating and cell division.
- Traditional methods to study dynein function, such as depletion or genetic manipulation, are time-consuming and require prolonged experimental periods.
- The discovery of ciliobrevins, cell-permeable small molecule inhibitors, enables acute and localized disruption of dynein activity.
Purpose of the Study:
- To review recent research utilizing ciliobrevins to inhibit dynein activity.
- To discuss the insights gained into dynein function in various cell types, with a specific focus on neuronal cells.
- To highlight the potential of ciliobrevins as novel research tools for assessing cellular dynein functions.
Main Methods:
- Review of existing scientific literature focusing on studies employing ciliobrevins.
- Analysis of research demonstrating the acute inhibition of dynein by ciliobrevins.
- Discussion of insights derived from experiments using ciliobrevins in diverse cellular contexts, particularly neurons.
Main Results:
- Ciliobrevins allow for rapid, acute, and both global and local inhibition of dynein motor proteins.
- Studies using ciliobrevins have provided new insights into the roles of dynein in cellular transport, migration, and division.
- These inhibitors have proven valuable in understanding dynein's function in neuronal cells, complementing established research techniques.
Conclusions:
- Ciliobrevins represent a significant advancement in the study of dynein motor proteins, offering a faster and more acute experimental approach.
- Further research is needed to fully elucidate the precise mechanism of action and specificity of ciliobrevins for dynein.
- Despite remaining questions, ciliobrevins are established as powerful and versatile tools for investigating the cellular roles of dyneins.

7.3K
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,...

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...

5.8K
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

The cytoskeletal architecture can be studied using different microscopic and biochemical techniques. Electron microscopy was instrumental in discovering the cytoskeletal architecture around the 1960s, which allowed obtaining structural information at a high-resolution level. However, the sample preparation procedure often limits this ability in biological samples. Several protocols have been developed over the years to optimize sample preparation. In one of the protocols known as rotary...

5.1K
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...
