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.

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.

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.

Astrin is required for the maintenance of sister chromatid cohesion and centrosome integrity [PDF]

, 2007
Faithful chromosome segregation in mitosis requires the formation of a bipolar mitotic spindle with stably attached chromosomes. Once all of the chromosomes are aligned, the connection between the sister chromatids is severed by the cysteine protease ...

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).

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 ...

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

Advanced Science, Volume 13, Issue 26, 8 May 2026.
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

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.

Serum Proteomic Analysis Using Gel‐Based Liquid Chromatography Tandem Mass Spectrometry Reveals Differences Between Canine Oral Malignancies and Non‐Malignant Conditions

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
This study establishes a GeLC‐MS/MS‐based serum proteomics workflow for canine oral oncology to differentiate malignancies from non‐malignant conditions. Comprehensive protein profiling, pathway analysis and protein–drug interaction mapping reveal candidate biomarkers and insights into the pathogenesis of canine oral cancers.
