Centrobin: a novel daughter centriole-associated protein that is required for centriole duplication.
In mammalian cells, the centrosome consists of a pair of centrioles and amorphous pericentriolar material. The pair of centrioles, which are the core components of the centrosome, duplicate once per cell cycle. Centrosomes play a pivotal role in orchestrating the formation of the bipolar spindle during mitosis.

SAK/PLK4 Is Required for Centriole Duplication and Flagella Development [PDF]
SAK/PLK4 is a distinct member of the polo-like kinase family. SAK-/- mice die during embryogenesis, whereas SAK+/- mice develop liver and lung tumors and SAK+/- MEFs show mitotic abnormalities. However, the mechanism underlying these phenotypes is still not known.Here, we show that downregulation of SAK in Drosophila cells, by mutation or RNAi, leads ...

CPAP insufficiency leads to incomplete centrioles that duplicate but fragment
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.

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

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.

The RAC1 activator Tiam1 regulates centriole duplication through controlling PLK4 levels
Centriole duplication is tightly controlled to maintain correct centriole number through the cell cycle. A key component of this control is the regulated degradation of PLK4, the master regulator of centriole duplication.

Revisiting Centrioles in Nematodes—Historic Findings and Current Topics
Theodor Boveri is considered as the “father” of centrosome biology. Boveri’s fundamental findings have laid the groundwork for decades of research on centrosomes.

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

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.

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