Summary
The centrosome, once enigmatic, is now recognized as crucial for cell-cycle progression and control. While not essential for spindle assembly, it plays key roles in initiating DNA replication and cell division.
Area of Science:
- Cell Biology
- Molecular Biology
Background:
- The centrosome's role has evolved from an obscure organelle to a central cellular regulator over the last century.
- Its precise functions in cell division and control are areas of active investigation.
Purpose of the Study:
- To review the current understanding of centrosome functions in cell-cycle progression.
- To highlight recent findings on the centrosome's non-spindle assembly roles and its regulation.
Main Methods:
- Literature review of studies on centrosome biology and cell division.
- Analysis of recent experimental data regarding centrosome function.
Main Results:
- Centrosomes are not essential for spindle assembly in all contexts.
- Evidence suggests centrosomes are important for initiating S phase and completing cytokinesis.
- Key molecules regulating centrosome duplication have been identified.
Conclusions:
- The centrosome is a critical regulator of cell-cycle progression and cellular control.
- Further research into centrosome-anchored activities will likely reveal new functions.

02:30Histone Variants at the Centromere
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 variants are also...
02:25Centrosome Duplication
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).

02:17Separation of Sister Chromatids
At the transition from prophase to metaphase, there is a reduction in cohesion along the chromosomal arms, resulting in the resolution of sister chromatids. However, residual cohesin connections remain to hold the sister chromatids together until the transition from metaphase to anaphase. The residual connection prevents any premature separation of sister chromatids, blocking the risks of aneuploidy within the daughter cells.

02:19The Spindle Assembly Checkpoint
The spindle assembly checkpoint is a molecular surveillance mechanism ensuring the fidelity of chromosome segregation during anaphase. The checkpoint monitors the completion of all the prerequisite steps before chromosome segregation to determine whether the segregation process should proceed or be delayed.
Many proteins function together to control the spindle assembly checkpoint. Mutations affecting these proteins may allow cells to proceed into anaphase prematurely, resulting in the...

01:13Centrioles and Centrosomes
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.
