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.

Direct binding of CEP85 to STIL ensures robust PLK4 activation and efficient centriole assembly

Nature Communications, 2018
Centriole duplication is tightly regulated in vivo, but the underlying molecular mechanisms are incompletely understood. Here the authors use high-resolution structural and imaging methods to show that CEP85 directly interacts with STIL and mediates ...

Feedback loops in the Plk4–STIL–HsSAS6 network coordinate site selection for procentriole formation

Biology Open, 2019
Centrioles are duplicated once in every cell cycle, ensuring the bipolarity of the mitotic spindle. How the core components cooperate to achieve high fidelity in centriole duplication remains poorly understood. By live-cell imaging of endogenously tagged

Phosphorylation at the Helm: Kinase‐Mediated Regulation of Primary Cilia Assembly and Disassembly

Cytoskeleton, Volume 82, Issue 11, Page 707-718, November 2025.
ABSTRACT The primary cilium serves as an antenna of most vertebrate cells and is important for conveying cues from several signaling pathways into appropriate cellular responses during development and homeostasis. Cilia assembly and disassembly processes are thought to be strictly controlled; however, the precise nature of molecular events underlying ...

Centrin-2 Is Required for Centriole Duplication in Mammalian Cells [PDF]

Current Biology, 2002
Centrosomes are the favored microtubule-organizing framework of eukaryotic cells. Centrosomes contain a pair of centrioles that normally duplicate once during the cell cycle to give rise to two mitotic spindle poles, each containing one old and one new centriole. However, aside from their role as an anchor point for pericentriolar material and as basal

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

Nature 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.

Chromosomal instability and genomic alterations in cholangiocarcinoma from Northeastern Thailand

The Journal of Pathology, Volume 267, Issue 3, Page 261-274, November 2025.
Abstract Cholangiocarcinoma (CCA) is a lethal cancer of the bile duct and is a major health concern in several parts of the world, including northeastern Thailand, where CCA incidence is the highest due to the endemic liver fluke Opisthorchis viverrini.

Proximity Interactions among Centrosome Components Identify Regulators of Centriole Duplication [PDF]

Current Biology, 2014
The centrosome consists of a pair of centrioles and surrounding pericentriolar material (PCM). Many vertebrate cells also have an array of granules, termed centriolar satellites, that localize around the centrosome and are associated with centrosome and cilium function.

Cytotoxicity of Atropisomeric [1,1′‐Binaphthalene]‐2,2′‐Diamines (BINAM) and Analogs in Human Cancer Cells: Enantioselectivity, Structure–Activity Relationships, and Mechanism

ChemMedChem, Volume 20, Issue 19, October 6, 2025.
It is reported for the first time that atropisomeric (R)‐[1,1′‐binaphthalene]‐2,2′‐diamine (R‐BINAM, 1(R)), but not (S)‐[1,1′‐binaphthalene]‐2,2′‐diamine (S‐BINAM, 1(S)), is a moderately potent spindle poison, causing antiproliferation, depolymerization of microtubules, multipolar spindles, pericentriolar material (PCM) fragmentation, mitotic ...

The interrelationship between APC/C and Plk1 activities in centriole disengagement

Biology Open, 2012
Summary Mother–daughter centriole disengagement, the necessary first step in centriole duplication, involves Plk1 activity in early mitosis and separase activity after APC/C activity mediates securin degradation.
