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 includes no centrioles and consists of a cylindrical layered core structure surrounded by a corona harboring microtubule-nucleating -tubulin complexes. It is the significant centrosomal model beyond animals and yeasts. Proteomics, protein interaction research by BioID and superresolution microscopy procedures led to considerable progress in our understanding of your composition, structure and function of this centrosome type. We discuss all at present identified components on the Dictyostelium centrosome in comparison to other centrosomes of animals and yeasts. Keywords: microtubule-organizing center; microtubule-organization; centrosome; Dictyostelium; mitosis1. Introduction 1.1. Centrosome Forms and Centrosome Duplication Centrosomes are proteinacious organelles finest known for their function as main microtubule organizing centers (MTOCs). They have been extensively studied since the late 19th century, once they were first characterized independently by three pioneers, Walther Flemming, Theodor Boveri and Edouard van Beneden [1]. Though studying cell division in various fertilized eggs and tissues they recognized a role of centrosomes in mitotic spindle formation and chromosome movements. Even though it swiftly became clear that centrosomes duplicate when per cell cycle and that they nucleate and organize microtubules, it took until the late eighties of your last century to get additional insight into the manner in which centrosomes manage to perform so, when -tubulin was identified as a third tubulin isoform needed for microtubule nucleation [5]. At that time, additionally, it became apparent that centrosomes consist solely of proteins, and–besides kinetochores–represent the biggest and most difficult protein complex inside a eukaryotic cell, 1-Methyladenosine supplier within the order of 100 diverse protein elements [6]. Comparative evolutional biology revealed that precursors of centrosomes have been currently a feature in the last eukaryotic typical ancestor (LECA) [7]. For the duration of evolution various centrosome varieties emerged (Figure 1), and inside a handful of branches with the eukaryotic tree of life, centrosomes were even lost, most prominently in greater plants. The most popular style of centrosome is characterized by the presence of centrioles, which consist of a nine-fold symmetric cylindrical assembly of short microtubules [10]. In G1, there’s a single older, mother centriole, and one younger, daughter centriole. Mostly the mother centriole is embedded within a h.
