Centrosome heterogeneity in stem cells regulates cell diversity. [PDF]
Stem cells are at the source of creating cellular diversity. Multiple mechanisms, including basic cell biological processes, regulate their fate. The centrosome is at the core of many stem cell functions and recent work highlights the association of ...

Investigating the cellular and molecular mechanisms involved in establishing and maintaining centrosome asymmetry in Drosophila neuroblasts [PDF]
Centrosome asymmetry has been implicated in stem cell fate maintenance in both flies and vertebrates. Drosophila neuroblasts, the neural precursors of the fly’s central nervous system, contain molecularly and physically asymmetric centrosomes.

The centrosomal protein C-Nap1 is required for cell cycle-regulated centrosome cohesion [PDF]
Duplicating centrosomes are paired during interphase, but are separated at the onset of mitosis. Although the mechanisms controlling centrosome cohesion and separation are important for centrosome function throughout the cell cycle, they remain poorly ...

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 ...

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 ...

Centrosome Biology: The Ins and Outs of Centrosome Assembly [PDF]
As a microtubule-organizing center, the centrosome undergoes a dramatic increase in size - via expansion of the pericentriolar material - during mitosis. Recent work reveals shared assembly properties of a protein scaffold that facilitates and supports this expansion, a process critical to spindle assembly.

Nuclei of Non-Muscle Cells Bind Centrosome Proteins upon Fusion with Differentiating Myoblasts [PDF]
Background: In differentiating myoblasts, the microtubule network is reorganized from a centrosome-bound, radial array into parallel fibres, aligned along the long axis of the cell.

The Cep57-pericentrin module organizes PCM expansion and centriole engagement
Centriole disengagement occurs towards mitotic exit and involves cleavage of pericentrin, a component of the pericentriolar material. Here the authors show that depletion of the centrosomal protein Cep57 leads to precocious centriole disengagement, and ...

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.
