Direct interaction between yeast spindle pole body components: Kar1p is required for Cdc31p localization to the spindle pole body
The Saccharomyces cerevisiae genes KAR1 and CDC31 are required for the initial stages of spindle pole body (SPB) duplication in yeast. The Cdc31 protein is most related to caltractin/centrin, a calcium-binding protein present in microtubule organizing centers in many organisms. Because of a variety of genetic interactions between CDC31 and KAR1 (Vallen, E. A., W. Ho. M. Winey, and M. D. Rose. 1...
متن کاملDirect Interaction between Yeast Spindle Pole Body Components: Karlp Is Required for Cdc31p Localization to the Spindle Pole Body
The Saccharomyces cerevisiae genes KAR/ and CDC31 are required for the initial stages of spindie pole body (SPB) duplication in yeast. The Cdc31 protein is most related to caltractin/centrin, a calciumbinding protein present in microtubule organizing centers in many organisms. Because of a variety of genetic interactions between CDC31 and KARl (VaUen, E. A., W. Ho, M. Winey, and M. D. Rose. 199...
متن کاملComponents of the yeast spindle and spindle pole body
Yeast spindle pole bodies (SPBs) with attached nuclear microtubles were enriched approximately 600-fold from yeast cell extracts. 14 mAbs prepared against this enriched SPB fraction define at least three components of the SPB and spindle. Immunofluorescent staining of yeast cells showed that throughout the cell cycle two of the components (110 and 90 kD) were localized exclusively to the SPB re...
متن کاملThe Cdc31p-binding protein Kar1p is a component of the half bridge of the yeast spindle pole body
KAR1 has been identified as an essential gene which is involved in karyogamy of mating yeast cells and in spindle pole body duplication of mitotic cells (Rose, M. D., and G. R. Fink. 1987. Cell. 48:1047-1060). We investigated the cell cycle-dependent localization of the Kar1 protein (Kar1p) and its interaction with other SPB components. Kar1p is associated with the spindle pole body during the ...
متن کاملSpindle 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 ...
