CPAP insufficiency leads to incomplete centrioles that duplicate but fragment

Journal of Cell Biology, 2022
Centrioles are structures that assemble centrosomes. CPAP is critical for centrosome assembly, and its mutations are found in patients with diseases such as primary microcephaly. CPAP’s centrosomal localization, its dynamics, and the consequences of its insufficiency in human cells are poorly understood.

The homo-oligomerisation of both Sas-6 and Ana2 is required for efficient centriole assembly in flies

eLife, 2015
Sas-6 and Ana2/STIL proteins are required for centriole duplication and the homo-oligomerisation properties of Sas-6 help establish the ninefold symmetry of the central cartwheel that initiates centriole assembly. Ana2/STIL proteins are poorly conserved,

Two-step phosphorylation of Ana2 by Plk4 is required for the sequential loading of Ana2 and Sas6 to initiate procentriole formation [PDF]

Open Biology, 2017
The conserved process of centriole duplication requires Plk4 kinase to recruit and promote interactions between Sas6 and Sas5/Ana2/STIL (respective nomenclature of worms/flies/humans).

Chromosomal Instability Drives Glioblastoma Heterogeneity and Therapeutic Opportunities

Advanced Science, Volume 13, Issue 39, 13 July 2026.
ABSTRACT Glioblastoma, the most aggressive and lethal form of brain cancer, is defined by profound genomic instability, with Chromosomal Instability (CIN) playing a central role in driving tumor progression, therapy resistance, and poor prognosis. CIN is characterized by numerical and structural alterations, is driven by mechanisms such as mitotic ...

Plk4/SAK/ZYG-1 in the regulation of centriole duplication [PDF]

F1000 Biology Reports, 2010
Centrioles organize both centrosomes and cilia. Centriole duplication is tightly regulated and coordinated with the cell cycle to limit duplication to only once per cell cycle. Defects in centriole number and structure are commonly found in cancer. Plk4/SAK and the functionally related Caenorhabditis elegans ZYG-1 kinases initiate centriole duplication.

Acto-myosin force organization modulates centriole separation and PLK4 recruitment to ensure centriole fidelity

Nature Communications, 2019
Centriolar separation is thought to be crucial for centriole duplication, but the mechanism behind separation is poorly understood. Here, using micropatterning, the authors report that actomyosin forces influence the direction, distance, and time of ...

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

Advanced Science, Volume 13, Issue 37, 3 July 2026.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...

Identification of Distinct Interacting Proteins of Giardia lamblia Centrins Using Yeast Two‐Hybrid Assays

Journal of Eukaryotic Microbiology, Volume 73, Issue 4, July/August 2026.
ABSTRACT Giardia lamblia, a protozoan parasite that causes diarrhea in humans, contains two centrins implicated in cellular morphology and cell division. To identify proteins interacting with each G. lamblia centrin (GlCent), we performed a yeast two‐hybrid assay.

CCDC84 Acetylation Oscillation Regulates Centrosome Duplication by Modulating HsSAS-6 Degradation

Cell Reports, 2019
Summary: In animal cells, centriole number is strictly controlled in order to guarantee faithful cell division and genetic stability, but the mechanism by which the accuracy of centrosome duplication is maintained is not fully understood.

Polo-like kinase 2-dependent phosphorylation of NPM/B23 on serine 4 triggers centriole duplication. [PDF]

PLoS ONE, 2010
Duplication of the centrosome is well controlled during faithful cell division while deregulation of this process leads to supernumary centrosomes, chromosome missegregation and aneuploidy, a hallmark of many cancer cells.
