![]() These results suggest that septins serve as a diffusion barrier for Lte1p, and that Cdc10p is needed for the septin ring to serve as a scaffold for a putative microtubule sensor. In sep7Delta, but not cdc10Delta, mutants, inappropriate mitotic exit depends on Lte1p. In sep7Delta and cdc10Delta mutants, Lte1p is mislocalized to the mother. In many ways they are analogous to the trigonometric functions, and they have the same. ![]() When movement of the spindle into the neck was delayed, mitotic exit occurred, inappropriately leaving both nuclei in the mother.

We found that the septin mutants sep7Delta and cdc10Delta are defective in the checkpoint. Displaying top 8 worksheets found for - Homologous And Analogous Structures. To investigate this mechanism, we examined mutants defective for septins, which compose a ring at the neck. However, the checkpoint functions without Lte1p and apparently senses cytoplasmic microtubules in the mother/bud neck. This segregation helps keep Tem1p in its inactive GDP state until the spindle enters the neck. Tem1p and its GTPase activating protein (GAP) Bub2p/Bfa1p are located on the daughter-bound spindle pole body. Mitotic exit is controlled by the small G protein Tem1p. In Saccharomyces cerevisiae, the spindle position checkpoint ensures that cells do not exit mitosis until the mitotic spindle moves into the mother/bud neck and thus guarantees that each cell receives one nucleus. ![]()
