Remote control of microtubule plus-end dynamics and function from the minus-end
eLife, 2019 In eukaryotes, the organization and function of the microtubule cytoskeleton depend on the allocation of different roles to individual microtubules. For example, many asymmetrically dividing cells differentially specify microtubule behavior at old and ...

Coping with centriole loss: pericentriolar material maintenance after centriole degeneration
Communications Biology, 2021 Shortly after the onset of ciliogenesis in Caenorhabditis elegans sensory neurons, the centrioles/basal bodies undergo degeneration. The fate of the pericentriolar material (PCM) that was associated with those centrioles has, however, remained unknown ...

Activation of ADF/cofilin by phosphorylation-regulated Slingshot phosphatase is required for the meiotic spindle assembly in Xenopus laevis oocytes [PDF]
, 2013 We identify Xenopus ADF/cofilin (XAC) and its activator, Slingshot phosphatase (XSSH), as key regulators of actin dynamics essential for spindle microtubule assembly during Xenopus oocyte maturation.

Perturbing Microtubule Integrity Blocks AMP-Activated Protein Kinase-Induced Meiotic Resumption in Cultured Mouse Oocytes [PDF]
, 2012 The oocyte meiotic spindle is comprised of microtubules (MT) that bind chromatin and regulate both metaphase plate formation and karyokinesis during meiotic maturation; however, little information is known about their role in meiosis reinitiation.

Evolution of microtubule organizing centers across the tree of eukaryotes [PDF]
The Plant Journal, 2013 SummaryThe architecture of eukaryotic cells is underpinned by complex arrrays of microtubules that stem from an organizing center, referred to as the MTOC. With few exceptions, MTOCs consist of two basal bodies that anchor flagellar axonemes and different configurations of microtubular roots.

Microtubules and Lis-1/NudE/dynein regulate invasive cell-on-cell migration in Drosophila. [PDF]
PLoS ONE, 2012 The environment through which cells migrate in vivo differs considerably from the in vitro environment where cell migration is often studied. In vivo many cells migrate in crowded and complex 3-dimensional tissues and may use other cells as the ...

Mechanism of how augmin directly targets the γ-tubulin ring complex to microtubules [PDF]
, 2018 Microtubules (MTs) must be generated from precise locations to form the structural frameworks required for cell shape and function. MTs are nucleated by the γ-tubulin ring complex (γ-TuRC), but it remains unclear how γ-TuRC gets to the right location ...

Microtubule-organizing centers: from the centrosome to non-centrosomal sites [PDF]
Current Opinion in Cell Biology, 2017 The process of cellular differentiation requires the distinct spatial organization of the microtubule cytoskeleton, the arrangement of which is specific to cell type. Microtubule patterning does not occur randomly, but is imparted by distinct subcellular sites called microtubule-organizing centers (MTOCs).

Centrioles without microtubules: a new morphological type of centriole
Biology Open, 2018 The centrosome is the organizing center of microtubules in the cell, the basis for the origin of cilia and flagella and a site for the concentration of a regulatory proteins multitude.
