Cell Cycle, 2010 In interphase and mitosis, centrosomes play a major role in the spatial organization of the microtubule network. Alterations in centrosome number and structure are associated with genomic instability and occur in many cancers. Centrosome duplication is controlled by centriole replication.

Mode of centriole duplication and distribution. [PDF]
The Journal of cell biology, 1990 Centriole stability and distribution during the mammalian cell cycle was studied by microinjecting biotinylated tubulin into early G1 cells and analyzing the pattern of incorporation into centrioles. Cells were extracted and cold treated to depolymerize labile microtubules, allowing the fluorescent microscopic visualization of the stable centrioles ...

Centrioles: Duplicating Precariously [PDF]
Current 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-

Investigation of human centrosomes - with a special focus on the function of Cep152 and Cep192 in centriole duplication [PDF]
, 2012 Centrioles are symmetrical, barrel-shaped, microtubule-based structures, that serve as building platforms for the formation of centrosomes and cilia. In dividing cells, they recruit a matrix of proteins called pericentriolar material (PCM) to form the ...

STIL binding to Polo-box 3 of PLK4 regulates centriole duplication [PDF]
, 2015 Polo-like kinases (PLK) are eukaryotic regulators of cell cycle progression, mitosis and cytokinesis; PLK4 is a master regulator of centriole duplication.

The E2F-DP1 Transcription Factor Complex Regulates Centriole Duplication in Caenorhabditis elegans
G3: Genes, Genomes, Genetics, 2016 Centrioles play critical roles in the organization of microtubule-based structures, from the mitotic spindle to cilia and flagella. In order to properly execute their various functions, centrioles are subjected to stringent copy number control.

Talpid3-binding centrosomal protein Cep120 is required for centriole duplication and proliferation of cerebellar granule neuron progenitors. [PDF]
PLoS ONE, 2014 Granule neuron progenitors (GNPs) are the most abundant neuronal type in the cerebellum. GNP proliferation and thus cerebellar development require Sonic hedgehog (Shh) secreted from Purkinje cells.

GCP6 is a substrate of Plk4 and required for centriole duplication [PDF]
Journal of Cell Science, 2012 Centriole duplication occurs once per cell cycle and requires Plk4, a member of the Polo-like kinase family. A key component of the centrosome is the γ-tubulin ring complex (γ-TuRC) that nucleates microtubules. GCP6 is a member of the γ-TuRC, but its role in human cells and the regulation of its functions remain unclear.

On the regulation of centriole duplication in human cells : exploring the interactions of polo-like kinase 4 with the centrosomal proteins Cep192 and STIL [PDF]
, 2015 Centrioles duplicate once in each cell cycle to give rise to two centrosomes that form the spindle poles during mitosis. Aberrant centriole duplication can result in the formation of supernumerary centrosomes, leading to incorrect spindle assembly and ...
