cellsReviewThe Dictyostelium CentrosomeRalph Gr , Marianne Grafe, Irene Meyer, Kristina Mitic and Valentin PitzenDepartment of Cell Biology, University of Potsdam, Karl-Liebknecht-Str. 245, 14476 Potsdam-Golm, Germany; [email protected] (M.G.); [email protected] (I.M.); [email protected] (K.M.); [email protected] (V.P.) Correspondence: [email protected]: The centrosome of Dictyostelium amoebae consists of no centrioles and consists of a cylindrical layered core structure surrounded by a corona harboring microtubule-nucleating -tubulin complexes. It is the important centrosomal model beyond animals and yeasts. Proteomics, protein interaction studies by BioID and superresolution microscopy strategies led to considerable progress in our understanding of the composition, structure and function of this centrosome type. We go over all at present known elements with the Dictyostelium centrosome in comparison to other centrosomes of animals and yeasts.

Centrosome Sorts and Centrosome Duplication Centrosomes are proteinacious organelles best identified for their function as important microtubule organizing centers (MTOCs). They have been extensively studied since the late 19th century, when they have been initial characterized independently by three pioneers, Walther Flemming, Theodor Boveri and Edouard van Beneden [1]. When studying cell division in various fertilized eggs and tissues they recognized a function of centrosomes in mitotic spindle formation and chromosome movements. Despite the fact that it speedily became clear that centrosomes duplicate after per cell cycle and that they nucleate and organize microtubules, it took till the late eighties from the final century to achieve additional insight in to the manner in which centrosomes handle to complete so, when -tubulin was identified as a third tubulin isoform essential for microtubule nucleation [5]. At that time, it also became apparent that centrosomes consist solely of proteins, and–besides kinetochores–represent the biggest and most difficult protein complicated inside a eukaryotic cell, within the order of 100 distinct protein components [6]. Comparative evolutional biology revealed that precursors of centrosomes had been already a feature of the final eukaryotic popular ancestor (LECA) [7]. Through evolution various centrosome kinds emerged (Azoxymethane Purity Figure 1), and inside a few branches with the eukaryotic tree of life, centrosomes were even lost, most prominently in larger plants. Essentially the most typical kind of centrosome is characterized by the presence of centrioles, which consist of a nine-fold symmetric cylindrical assembly of brief microtubules [10]. In G1, there is 1 older, mother centriole, and a single younger, daughter centriole. Mostly the mother centriole is embedded in a h.
