Summary
Dyneins are motor proteins crucial for cell movement and cargo transport. This review details cytoplasmic dynein-1 and ciliary dyneins, exploring their structures, functions, and regulation by accessory proteins.
Area of Science:
- Molecular Biology
- Cell Biology
Background:
- Dyneins are microtubule-based motor proteins essential for cellular functions.
- Cytoplasmic dynein (dynein-1) handles intracellular transport, organelle anchoring, and nuclear migration.
- Ciliary dyneins are vital for intraflagellar transport and ciliary beating.
Purpose of the Study:
- To provide a comprehensive overview of dynein motor proteins.
- To highlight the structure, mechanism, and regulation of dynein-1.
- To describe the distinct features and cellular roles of other dyneins, including dynein-2.
Main Methods:
- Review of existing literature on dynein motor proteins.
- Analysis of the structure and function of dynein-1.
- Examination of the roles and characteristics of ciliary dyneins.
Main Results:
- Dynein-1 is the primary motor for retrograde intracellular transport and mechanical force generation.
- Dynein-2 mediates retrograde intraflagellar transport, crucial for cilia and flagella.
- Other ciliary dyneins generate force for ciliary motility by sliding microtubules.
Conclusions:
- Dynein motors exhibit diverse structures and functions critical for cellular processes.
- Accessory proteins play a key role in modulating dynein activity in various cellular contexts.
- Understanding dynein diversity and regulation is vital for comprehending cell motility and transport mechanisms.

8.0K
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...

01:43The Movement of Organelles and Vesicles
4.5K
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,...

3.7K
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...

3.3K
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...

02:15The Contractile Ring
6.4K
Contractile rings are composed of microfilaments and are responsible for separating the daughter cells during cytokinesis. Contractile ring assembly proceeds along with other cell cycle events; however, very few mechanistic details are known about the timing and coordination of the contractile rings with the cell cycle.
A small GTPase, RhoA, controls the function and assembly of the contractile ring. RhoA belongs to the Ras superfamily of proteins. The activation of formins by RhoA promotes...

01:08The Sarcomere
8.1K
A sarcomere is a microscopic segment repeating in a myofibril. The sarcomere fundamentally consists of two main myofilaments: thick filaments called myosin and thin filaments called actin. These filaments interact by sliding past each other in response to stimulus. In addition to myosin and actin, several other proteins, such as tropomyosin, troponin, titin, nebulin, myomesin, α-actinin, and dystrophin, play crucial roles in regulating, structuring, and functioning of the sarcomere.
