Revisiting the Role of the Mother Centriole in Centriole Biogenesis [PDF]

open access: yesScience, 2007
Centrioles duplicate once in each cell division cycle through so-called templated or canonical duplication. SAK, also called PLK4 (SAK/PLK4), a kinase implicated in tumor development, is an upstream regulator of canonical biogenesis necessary for centriole formation.

Centriole structure [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2014
Centrioles are among the largest protein-based structures found in most cell types, measuring approximately 250 nm in diameter and approximately 500 nm long in vertebrate cells. Here, we briefly review ultrastructural observations about centrioles and associated structures.

Promotion and Suppression of Centriole Duplication Are Catalytically Coupled through PLK4 to Ensure Centriole Homeostasis [PDF]

open access: yesCell Reports, 2016
PLK4 is the major kinase driving centriole duplication. Duplication occurs only once per cell cycle, forming one new (or daughter) centriole that is tightly engaged to the preexisting (or mother) centriole.

Centriole length control [PDF]

open access: yesCurrent Opinion in Structural Biology, 2021
Centrioles are microtubule-based structures involved in cell division and ciliogenesis. Centriole formation is a highly regulated cellular process and aberrations in centriole structure, size or numbers have implications in multiple human pathologies. In this review, we propose that the proteins that control centriole length can be subdivided into two ...

9-fold symmetry is not essential for centriole elongation and formation of new centriole-like structures [PDF]

open access: yesNature Communications
As daughter centrioles assemble during G2, they recruit conserved Ana3/RTTN followed by its partner Rcd4/PPP1R35. Together, this contributes to the subsequent recruitment of Ana1/CEP295, required for the centriole’s conversion to a centrosome.

The sperm centrioles

open access: yesMolecular and Cellular Endocrinology, 2020
Centrioles are eukaryotic subcellular structures that produce and regulate massive cytoskeleton superstructures. They form centrosomes and cilia, regulate new centriole formation, anchor cilia to the cell, and regulate cilia function. These basic centriolar functions are executed in sperm cells during their amplification from spermatogonial stem cells ...

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

open access: yeseLife, 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 ...

Building the Centriole [PDF]

open access: yesCurrent Biology, 2010
Centrioles are conserved microtubule-based organelles that lie at the core of the animal centrosome and play a crucial role in nucleating the formation of cilia and flagella in most eukaryotes. Centrioles have a complex ultrastructure with ninefold symmetry and a well-defined length.

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

open access: yesPLoS 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.

Centrioles without microtubules - a new morphological type of centriole [PDF]

open access: yesBiology Open, 2018
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.
