Spindle pole body components are reorganized during fission yeast meiosis
During meiosis, the centrosome/spindle pole body (SPB) must be regulated in a manner distinct from that of mitosis to achieve a specialized cell division that will produce gametes. In this paper, we demonstrate that several SPB components are localized to SPBs in a meiosis-specific manner in the fission yeast Schizosaccharomyces pombe. SPB components, such as Cut12, Pcp1, and Spo15, which stay ...
متن کاملKinetics of spindle pole body separation in budding yeast.
In the budding yeast Saccharomyces cerevisiae, the spindle pole body (SPB) serves as the microtubule-organizing center and is the functional analog of the centrosome of higher organisms. By expressing a fusion of a yeast SPB-associated protein to the Aequorea victoria green fluorescent protein, the movement of the SPBs in living yeast cells undergoing mitosis was observed by fluorescence micros...
متن کاملMicrotubule Nucleation at Non-Spindle Pole Body Microtubule-Organizing Centers Requires Fission Yeast Centrosomin-Related Protein mod20p
BACKGROUND Many types of differentiated eukaryotic cells display microtubule distributions consistent with nucleation from noncentrosomal intracellular microtubule organizing centers (MTOCs), although such structures remain poorly characterized. In fission yeast, two types of MTOCs exist in addition to the spindle pole body, the yeast centrosome equivalent. These are the equatorial MTOC, which ...
متن کاملInterphase microtubule bundles use global cell shape to guide spindle alignment in fission yeast.
Correct spindle alignment requires a cell to detect and interpret its global geometry and to communicate this information to the mitotic spindle. In the fission yeast, Schizosaccharomyces pombe, the mitotic spindle is aligned with the longitudinal axis of the rod-shaped cell. Here, using wild-type and cell-shape mutants we investigate the mechanism of initial spindle alignment and show that att...
متن کاملThe Msd1–Wdr8–Pkl1 complex anchors microtubule minus ends to fission yeast spindle pole bodies
The minus ends of spindle microtubules are anchored to a microtubule-organizing center. The conserved Msd1/SSX2IP proteins are localized to the spindle pole body (SPB) and the centrosome in fission yeast and humans, respectively, and play a critical role in microtubule anchoring. In this paper, we show that fission yeast Msd1 forms a ternary complex with another conserved protein, Wdr8, and the...
