Summary
Intraflagellar transport (IFT) is crucial for building and maintaining eukaryotic cilia and flagella, essential for cell motility and signaling. This review details IFT machinery and cargo transport mechanisms, highlighting its role in development and human diseases called ciliopathies.
Area of Science:
- Cell Biology
- Molecular Biology
- Developmental Biology
Background:
- Eukaryotic cilia and flagella are conserved organelles critical for cellular motility and signaling.
- Intraflagellar transport (IFT) is a bidirectional transport system essential for the assembly and maintenance of these organelles.
- IFT is vital for mammalian development, and its defects lead to human diseases known as ciliopathies.
Purpose of the Study:
- To review current knowledge on intraflagellar transport (IFT).
- To emphasize the IFT machinery involved in ciliary assembly and maintenance.
- To explore specific mechanisms of ciliary cargo recognition and transport.
Main Methods:
- Review of existing literature on intraflagellar transport.
- Analysis of molecular mechanisms governing IFT.
- Examination of model organisms to understand IFT processes.
Main Results:
- IFT is a complex, multicomponent system responsible for moving cargo along cilia and flagella.
- Specific molecular players and mechanisms for cargo recognition and transport have been identified.
- IFT machinery is conserved across species and essential for cellular function.
Conclusions:
- Intraflagellar transport is fundamental for cilia/flagella function, impacting development and health.
- Understanding IFT machinery and cargo transport is key to addressing ciliopathies.
- Continued research into IFT mechanisms will provide further insights into cellular processes.

11.4K
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
7.1K
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,...

5.0K
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...

01:19Translocation of Proteins into the Mitochondria
13.6K
Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

5.9K
Mitochondria are double-membrane organelles of the eukaryotes involved in cellular metabolism, signaling, ATP synthesis, and programmed cell death. Each of these processes requires specific proteins and enzymes that must be correctly sorted to the right mitochondrial subcompartment for the proper functioning of the organelle.
Most of these mitochondrial proteins are encoded by the nucleus and imported to the mitochondria as unfolded or loosely folded precursors. Mitochondrial precursors...
