lüll Severing all ties between mother and daughter: cell separation in budding yeast Yeong FMMol Microbiol 2005[Mar]; 55 (5): 1325-31At the end of nuclear division in the budding yeast, acto-myosin ring contraction and cytokinesis occur between mother and daughter cells. This is followed by cell separation, after which mother and daughter cells go their separate ways. While cell separation may be the last event that takes place between the two cells, it is nonetheless under tight regulation which ensures that both cells are viable upon separation. It is becoming increasingly clear that the components of the cell separation machinery are controlled at various levels, including the temporal and spatial regulation of the genes encoding for the components and the specific localization of the components to the neck. In addition, these regulatory controls are co-ordinated with exit from mitosis, thereby placing a mechanistic link between the end of mitosis and cell separation. More importantly, the success of the cell separation event is contingent upon the presence of a trilaminar septum, whose assembly is dependent on a host of proteins which localize to the neck over the span of one cell division cycle.|*Cell Compartmentation[MESH]|Cell Division/*physiology[MESH]|Mitosis/*physiology[MESH]|Saccharomyces cerevisiae/*cytology/physiology[MESH] |
