Experimental and Natural Induction of de novo Centriole Formation

Frontiers in Cell and Developmental Biology, 2022
In cycling cells, new centrioles are assembled in the vicinity of pre-existing centrioles. Although this canonical centriole duplication is a tightly regulated process in animal cells, centrioles can also form in the absence of pre-existing centrioles ...

McIdas localizes to centrioles and controls centriole numbers through PLK4-dependent phosphorylation [PDF]

EMBO Reports
The centriole duplication cycle must be tightly controlled and coordinated with the chromosome cycle. Aberrations in centriole biogenesis can cause developmental disorders, ciliopathies and cancer, yet the molecular determinants controlling centriole ...

Rapid Evolution of Sperm Produces Diverse Centriole Structures that Reveal the Most Rudimentary Structure Needed for Function

Cells, 2018
Centrioles are ancient subcellular protein-based organelles that maintain a conserved number and structure across many groups of eukaryotes. Centriole number (two per cells) is tightly regulated; each pre-existing centriole nucleates only one centriole ...

The SKP1-Cullin-F-box E3 ligase βTrCP and CDK2 cooperate to control STIL abundance and centriole number [PDF]

Open Biology, 2018
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.

Multimodal mechanisms of human centriole engagement and disengagement

EMBO Journal
Centrioles are unique cellular structures that replicate to produce identical copies, ensuring accurate chromosome segregation during mitosis. A new centriole, the “daughter”, is assembled adjacent to an existing “mother” centriole.

C. elegans SSNA-1 is required for the structural integrity of centrioles and bipolar spindle assembly [PDF]

Nature Communications
Centrioles play key roles in mitotic spindle assembly. Once assembled, centrioles exhibit long-term stability, but how stability is achieved and how it is regulated are not completely understood.

Assembly and mother centriole recruitment of IFT-B subcomplexes to form IFT-B holocomplex [PDF]

Cell Structure and Function
For the biogenesis and maintenance of cilia, bidirectional protein trafficking within cilia is crucial, and is conducted by intraflagellar transport (IFT) trains containing the IFT-A and IFT-B complexes that are powered by dynein-2 and kinesin-II motors.

PLK4 drives centriole amplification and apical surface area expansion in multiciliated cells

eLife, 2022
Multiciliated cells (MCCs) are terminally differentiated epithelia that assemble multiple motile cilia used to promote fluid flow. To template these cilia, MCCs dramatically expand their centriole content during a process known as centriole amplification.

Mechanical stretch scales centriole number to apical area via Piezo1 in multiciliated cells

eLife, 2021
How cells count and regulate organelle number is a fundamental question in cell biology. For example, most cells restrict centrioles to two in number and assemble one cilium; however, multiciliated cells (MCCs) synthesize hundreds of centrioles to ...

CDK11(p58) is required for centriole duplication and Plk4 recruitment to mitotic centrosomes. [PDF]

PLoS ONE, 2011
BACKGROUND: CDK11(p58) is a mitotic protein kinase, which has been shown to be required for different mitotic events such as centrosome maturation, chromatid cohesion and cytokinesis.
