Project description:

Title:
Mechanistic studies of the spindle position checkpoint
Summary:
In asymmetrically dividing cells, such as stem cells or budding yeast, the differential distribution of cell fate determinants and/or cellular components depends on the correct orientation of the mitotic spindle. In certain cell types, including budding yeast and Drosophila germline stem cells, spindle mis-orientation is sensed by a surveillance mechanism. In yeast, this mechanism, named as the spindle orientation checkpoint (SPOC), is essential for genome integrity and cell survival (Pereira and Yamashita, 2011; Caydasi et al., 2010, 2012).

The aim of this project is to investigate how novel SPOC components inhibit the onset of cell division in cells with a defective spindle apparatus in budding yeast. For this, the successful candidate will employ a combination of advanced microscopy, proteomic and genomic approaches to analyse protein localization, complex formation and phenotypes associated with loss- and gain-of-function mutants.
