Building a centriole [PDF]

open access: yesCurrent Opinion in Cell Biology, 2013
Centrioles are the key foundation of centrosomes and cilia, yet a molecular understanding of how they form has only recently begun to emerge. Building a fully functional centriole that can form a centrosome and cilium requires two cell cycles. Centriole building starts with procentriole nucleation, a process that is coordinated by the conserved ...

cNap1 bridges centriole contact sites to maintain centrosome cohesion

open access: yesPLoS Biology, 2022
Centrioles are non-membrane-bound organelles that participate in fundamental cellular processes through their ability to form physical contacts with other structures.

CEP19 cooperates with FOP and CEP350 to drive early steps in the ciliogenesis programme [PDF]

open access: yesOpen Biology, 2017
Primary cilia are microtubule-based sensory organelles necessary for efficient transduction of extracellular cues. To initiate cilia formation, ciliary vesicles (CVs) are transported to the vicinity of the centrosome where they dock to the distal end of ...

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.

Stabilization of Cartwheel-less Centrioles for Duplication Requires CEP295-Mediated Centriole-to-Centrosome Conversion

open access: yesCell Reports, 2014
Vertebrate centrioles lose their geometric scaffold, the cartwheel, during mitosis, concurrently with gaining the ability to recruit the pericentriolar material (PCM) and thereby function as the centrosome.

Centriole movements in mammalian epithelial cells during cytokinesis

open access: yesBMC Cell Biology, 2010
Background In cytokinesis, when the cleavage furrow has been formed, the two centrioles in each daughter cell separate. It has been suggested that the centrioles facilitate and regulate cytokinesis to some extent.

Cell Cycle‐Specific Regulation of Centrosome Clustering Dynamics in Cancer Cells by the Multifunctional Kinesin HSET

open access: yesAdvanced Science, EarlyView.
CDK5RAP2 associates with the kinesin HSET and forms co‐condensates. HSET motors drive the directional transport of CDK5RAP2 condensates toward microtubule minus ends. During mitosis, HSET self‐assembly further stabilizes clustered centrosomes, thereby enabling pseudo‐bipolar spindle formation in cancer cells with supernumerary centrosomes. Upon mitotic

Insights into centriole geometry revealed by cryotomography of doublet and triplet centrioles

open access: yeseLife, 2018
Centrioles are cylindrical assemblies comprised of 9 singlet, doublet, or triplet microtubules, essential for the formation of motile and sensory cilia.

Centrioles: Duplicating Precariously [PDF]

open access: yesCurrent Biology, 2007
To assemble a mitotic spindle and accurately segregate chromosomes to progeny, a cell needs to precisely regulate its centrosome number, a feat largely accomplished through the tight control of centriole duplication. Recent work showing that the overexpression of centriolar proteins can lead to the formation of multiple centrioles in the absence of pre-

Unveiling a New Link: Cholesterol Deficiency in Smith–Lemli–Opitz and Niemann–Pick C as a Driver of Ciliopathies

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The ciliopathies are a group of genetic disorders caused by defective function of either the primary cilia (a large number) or the motile cilia (a much smaller number). These have been defined as diseases with mutations in genes encoding individual ciliary or cilia‐associated proteins.
