Summary
The centrosome, a vital cell structure, organizes microtubules and forms cilia. This review explores its conserved functions and general principles across diverse organisms.
Area of Science:
- Cell Biology
- Evolutionary Biology
Background:
- The centrosome, composed of centrioles and pericentriolar material, is evolutionarily conserved across diverse taxa.
- It plays a crucial role in organizing the microtubule cytoskeleton during mitosis and interphase.
Purpose of the Study:
- To review the conserved functions of the centrosome.
- To discuss the general principles governing centrosome operation.
Main Methods:
- Literature review of centrosome research.
- Comparative analysis of centrosome structure and function across different organisms.
Main Results:
- Centrosomes are essential for microtubule organization and cilia formation (primary and motile).
- They act as signaling hubs, concentrating cell cycle regulatory proteins.
- Centrosome structure and function show remarkable conservation over a billion years of evolution.
Conclusions:
- The centrosome is a fundamental organelle with multifaceted roles beyond microtubule organization.
- Understanding centrosome function provides insights into cell cycle regulation, development, and disease.
- General principles govern centrosome operation, despite some exceptions.

01:13Centrioles and Centrosomes
4.7K
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.

02:25Centrosome Duplication
4.6K
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).

02:30Histone 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...

02:27The Mitotic Spindle
7.5K
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.

02:50Spindle 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...

02:57Attachment of Sister Chromatids
3.7K
As cells progress into mitosis, the nuclear envelope breaks down, and the condensed chromosomes are exposed to the array of bipolar microtubules of the mitotic spindle. The kinetochore, a large, disc-shaped protein complex, is present at the centromere region of the sister chromatids and acts as a binding site for the microtubules. Usually, the plus-end of a single microtubule is embedded within the kinetochore. However, some kinetochores first establish lateral contact with the side-wall...
