Summary
The centriole, a large cell component, has its overall structure visualized using advanced imaging. This review details its organization, sub-regions, and protein makeup, despite its atomic structure remaining unknown.
Area of Science:
- Cell Biology
- Structural Biology
- Molecular Assembly
Background:
- The centriole is a massive molecular assembly within eukaryotic cells, crucial for various cellular functions.
- Despite its significance, the complete atomic structure of the centriole remains elusive.
- Existing knowledge relies on various imaging techniques providing a global architectural perspective.
Purpose of the Study:
- To review the current understanding of the centriole's overall organization.
- To highlight key sub-structural elements and their variations across species.
- To discuss the putative protein composition of centriole sub-structures.
Main Methods:
- Electron microscopy
- Cryo-electron tomography
- Super-resolution microscopy
Main Results:
- Establishment of a global architectural view of the centriole and its sub-regions.
- Identification of differences in centriole structure between species.
- Proposals for the protein composition of various centriole sub-structures.
Conclusions:
- Current imaging techniques provide significant insights into centriole architecture.
- A complete atomic-level understanding of the centriole is still a future goal.
- Further research is needed to bridge the gap towards an atomic view.

Centrioles and Centrosomes
4.6K
Most animal cells comprise a pair of centrioles together called a centrosome. The cell duplicates its centrosome and contains two centrosomes side-by-side, which begin to move apart during the prophase. As the centrosomes migrate to two different sides of the cell, microtubules start extending from each centrosome toward the other end. The mitotic spindle is composed of the centrosomes and their emerging microtubules.

Centrosome Duplication
4.5K
The primary microtubule organizing center (MTOC) in animal cells is the centrosome. A centrosome has two cylindrical centrioles at its core. Each centriole consists of nine sets of three microtubules held together by proteins. The centrioles are positioned at right angles to each other and surrounded by a shapeless protein cloud called the pericentriolar matrix, or pericentriolar material (PCM).

Histone Variants at the Centromere
4.8K
Histone variants are the histone proteins with structural and sequence variations. These variants may be regarded as “mutant” forms that replace their canonical histone counterparts in the nucleosomes. Specific post-translational modifications on the histone variants enable further chromatin complexity and regulate tissue-specific gene expression. The most common histone variants are from histone H2A, H2B, and linker histone H1 families. However, several variants of histone H3...

Spindle Assembly
4.0K
Spindle assembly occurs through three, often coexisting, pathways – the centrosome-mediated pathway, the chromatin-mediated pathway, and the microtubule-mediated pathway – collectively contributing to form a robust spindle apparatus.
In most cells, centrosomes are the primary microtubule nucleation centers. In the centrosome-mediated pathway, the G2-prophase transition triggers centrosome maturation and increased microtubule nucleation. Progressive nucleation results in a...

Microtubules in Cell Motility
4.2K
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...

The Mitotic Spindle
7.4K
The mitotic spindle—or spindle apparatus—is a eukaryotic, cytoskeletal structure made up of long protein fibers called microtubules. Formed during cell division, the spindle separates sister chromatids and moves them to opposite ends of a parental cell, where the now individual chromosomes are distributed to two daughter cell nuclei.
The bipolar configuration of the mitotic spindle facilitates chromosomal segregation, preparing the cell for division. One mechanism that ensures...
