Architecture of the centriole cartwheel‐containing region revealed by cryo‐electron tomography
Centrioles are evolutionarily conserved barrels of microtubule triplets that form the core of the centrosome and the base of the cilium. While the crucial role of the proximal region in centriole biogenesis has been well documented, its native ...

Centrioles without microtubules - a new morphological type of centriole [PDF]
The centrosome is the organizing center of microtubules in the cell, the basis for the origin of cilia and flagella and a site for the concentration of a regulatory proteins multitude. The centrosome comprises two centrioles surrounded by pericentriolar material.

Asymmetric Centriole Numbers at Spindle Poles Cause Chromosome Missegregation in Cancer
Chromosomal instability is a hallmark of cancer and correlates with the presence of extra centrosomes, which originate from centriole overduplication. Overduplicated centrioles lead to the formation of centriole rosettes, which mature into supernumerary ...

Centrioles are submicron-scale, barrel-shaped organelles typically found in pairs, and play important roles in ciliogenesis and bipolar spindle assembly.

A novel Cep120-dependent mechanism inhibits centriole maturation in quiescent cells [PDF]
The two centrioles of the centrosome in quiescent cells are inherently asymmetric structures that differ in age, morphology and function. How these asymmetric properties are established and maintained during quiescence remains unknown. Here, we show that

Regulation of cilia abundance in multiciliated cells
Multiciliated cells (MCC) contain hundreds of motile cilia used to propel fluid over their surface. To template these cilia, each MCC produces between 100-600 centrioles by a process termed centriole amplification.

The SKP1-Cullin-F-box E3 ligase βTrCP and CDK2 cooperate to control STIL abundance and centriole number [PDF]
Deregulation of centriole duplication has been implicated in cancer and primary microcephaly. Accordingly, it is important to understand how key centriole duplication factors are regulated.

Polo-like kinase 4 controls centriole duplication but does not directly regulate cytokinesis. [PDF]
Centrioles organize the centrosome, and accurate control of their number is critical for the maintenance of genomic integrity. Centrioles duplicate once per cell cycle, and duplication is coordinated by Polo-like kinase 4 (Plk4).

WDR90 is a centriolar microtubule wall protein important for centriole architecture integrity
Centrioles are characterized by a nine-fold arrangement of long-lived microtubule triplets that are held together by an inner protein scaffold. These structurally robust organelles experience strenuous cellular processes such as cell division or ciliary ...

Role for polo-like kinase 4 in mediation of cytokinesis. [PDF]
The mitotic protein polo-like kinase 4 (PLK4) plays a critical role in centrosome duplication for cell division. By using immunofluorescence, we confirm that PLK4 is localized to centrosomes.
