Basal body duplication in Paramecium requires γ-tubulin
First discovered in the fungus Aspergillus nidulans [1], g-tubulin is a ubiquitous component of microtubule organizing centres [2]. In centrosomes, g-tubulin has been immunolocalized at the pericentriolar material, suggesting a role in cytoplasmic microtubule nucleation [3], as well as within the centriole core itself [4]. Although its function in the nucleation of the mitotic spindle and of cy...
متن کاملBasal Body Duplication and Maintenance Require One Member of the Tetrahymena thermophila Centrin Gene Family□D
Centrins, small calcium binding EF-hand proteins, function in the duplication of a variety of microtubule organizing centers. These include centrioles in humans, basal bodies in green algae, and spindle pole bodies in yeast. The ciliate Tetrahymena thermophila contains at least four centrin genes as determined by sequence homology, and these have distinct localization and expression patterns. C...

متن کاملCentrin Deficiency in Paramecium Affects the Geometry of Basal-Body Duplication
BACKGROUND Ciliary or flagellar basal bodies and centrioles share the same architecture and remarkable property of duplicating once per cell cycle. Duplication is known to proceed by budding of the daugther organelle close to and at right angles to the mother structure, but the molecular basis of this geometry remains unknown. Among the handful of proteins implicated in basal-body/centriole dup...
متن کاملSas-4 proteins are required during basal body duplication in Paramecium
Centrioles and basal bodies are structurally related organelles composed of nine microtubule (MT) triplets. Studies performed in Caenorhabditis elegans embryos have shown that centriole duplication takes place in sequential way, in which different proteins are recruited in a specific order to assemble a procentriole. ZYG-1 initiates centriole duplication by triggering the recruitment of a compl...
