Chromosome Segregation: Disarming the Protector
One of the key features of meiosis is that shugoshin in complex with protein phosphatase 2A (PP2A) protects centromeric cohesin during meiosis I, but not during meiosis II. A new model suggests that a PP2A inhibitor mediates deprotection of centromeric cohesin during meiosis II.
متن کاملStudies on Auxin Protectors. IV. The Effect of Manganese on Auxin Protector-I of the Japanese Morning Glory.
Auxin protector-I of the Japanese morning glory is inactivated by manganese. Experiments carried out in vitro indicate that in the absence of oxygen the manganic, but not the manganous, ion rapidly inactivates the protector. It is clear from these, and other data described in this report, and the results of other workers, that in the presence of oxygen, manganese accelerates auxin inactivation ...
متن کاملHow to protect the protector?
This paper describes ongoing research to harden the lower part of the software stack, normally not covered by existing software-based fault-tolerance mechanisms. I discuss a combination of four techniques to harden the operating system kernel against hardware faults: resilient data structures, asynchronous checks, restartable OS services, and message protection. I present initial performance re...

متن کاملAldosterone: villain or protector?
During the past decade, there has been heightened interest in aldosterone as a cardiovascular risk factor, fueled by studies documenting its effects on tissues other than epithelial cells. Of particular interest is the role of aldosterone in exacerbating vascular injury. It is likely that the mechanisms mediating the vascular effects of aldosterone differ from its effects on epithelial cells, e...
