The Dictyostelium Centrosome [PDF]
The centrosome of Dictyostelium amoebae contains no centrioles and consists of a cylindrical layered core structure surrounded by a corona harboring microtubule-nucleating γ-tubulin complexes. It is the major centrosomal model beyond animals and yeasts.

Centrosomal and Non-centrosomal Functions Emerged through Eliminating Centrosomes
Centrosomes are highly conserved organelles that act as the major microtubule-organizing center (MTOC) in animal somatic cells. Through their MTOC activity, centrosomes play various roles throughout the cell cycle, such as supporting cell migration in interphase and spindle organization and positioning in mitosis.

Centrosome Biology: Polymer-Based Centrosome Maturation [PDF]
The molecular mechanisms that control how the centrosome increases in size and microtubule nucleation capacity during mitosis have remained elusive. Recent work using in vitro assays provide exciting clues as to how this may occur.

Centrosome-Associated NDR Kinase Regulates Centrosome Duplication [PDF]
Human NDR kinases are upregulated in some cancer types, yet their functions still remain undefined. Here, we report the first known function of a mammalian NDR kinase by demonstrating that human NDR directly contributes to centrosome duplication. A subpopulation of endogenous NDR localizes to centrosomes in a cell-cycle-dependent manner. Overexpression

Influence of M-phase chromatin on the anisotropy of microtubule asters [PDF]
In many eukaryotic cells going through M-phase, a bipolar spindle is formed by microtubules nucleated from centrosomes. These microtubules, in addition to being "captured" by kinetochores, may be stabilized by chromatin in two different ways: short-range

The phosphorylation of PHF5A by TrkA-ERK1/2-ABL1 cascade regulates centrosome separation
During interphase, the newly duplicated pairs of centrosomes are held together by a centrosome linker, and the centrosome separation needs the disruption of this linker to induce the duplicated centrosomes separating into two distinct microtubule ...

Cep295 is a conserved scaffold protein required for generation of a bona fide mother centriole
Newly formed centrioles mature into functional mother centrioles. Here the authors show that the scaffolding protein Cep295 is recruited to the procentriole assembly site and assists daughter centriole assembly and daughter-to-mother centriole conversion.

Bimodal Binding of STIL to Plk4 Controls Proper Centriole Copy Number
Summary: The number of centrioles is tightly controlled to ensure bipolar spindle assembly, which is a prerequisite to maintain genome integrity. However, our understanding of the fundamental principle that governs the formation of a single procentriole ...

Emerging roles of centrosome cohesion
The centrosome, consisting of centrioles and the associated pericentriolar material, is the main microtubule-organizing centre (MTOC) in animal cells.
