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 ...

Integrity of the Pericentriolar Material Is Essential for Maintaining Centriole Association during M Phase.

open access: yesPLoS ONE, 2015
A procentriole is assembled next to the mother centriole during S phase and remains associated until M phase. After functioning as a spindle pole during mitosis, the mother centriole and procentriole are separated at the end of mitosis.

Centriole length control

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 ...

Functional Analysis of Hydrolethalus Syndrome Protein HYLS1 in Ciliogenesis and Spermatogenesis in Drosophila

open access: yesFrontiers in Cell and Developmental Biology, 2020
Cilia and flagella are conserved subcellular organelles, which arise from centrioles and play critical roles in development and reproduction of eukaryotes. Dysfunction of cilia leads to life-threatening ciliopathies.

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

open access: yesCells, 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 ...

Polo-like kinase 4 controls centriole duplication but does not directly regulate cytokinesis. [PDF]

open access: yes, 2012
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).

Centriole inheritance [PDF]

open access: yesPrion, 2008
Early cell biologists perceived centrosomes to be permanent cellular structures. Centrosomes were observed to reproduce once each cycle and to orchestrate assembly a transient mitotic apparatus that segregated chromosomes and a centrosome to each daughter at the completion of cell division.

Role for polo-like kinase 4 in mediation of cytokinesis. [PDF]

open access: yes, 2019
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.

Centriole evolution [PDF]

open access: yesCurrent Opinion in Cell Biology, 2009
Centrioles are cylindrical structures found at the core of the mitotic spindle pole, which also act as basal bodies to nucleate the formation of cilia. Centrioles have a complex, ninefold symmetric structure, and reproduce by an intriguing duplication process. The complexity and apparent self-reproduction of centrioles raises the question of how such a

Protein Phosphatase 1 Down Regulates ZYG-1 Levels to Limit Centriole Duplication. [PDF]

open access: yesPLoS Genetics, 2017
In humans perturbations of centriole number are associated with tumorigenesis and microcephaly, therefore appropriate regulation of centriole duplication is critical. The C.
