Two-Stage Mechanism For Activation Of The Dna Replication Checkpoint Kinase Cds1 In Fission Yeast, Xu Yong, Matthew Davenport, Thomas Kelly
Two-Stage Mechanism For Activation Of The Dna Replication Checkpoint Kinase Cds1 In Fission Yeast, Xu Yong, Matthew Davenport, Thomas Kelly

The DNA replication checkpoint is a complex signal transduction pathway, present in all eukaryotic cells, that functions to maintain genomic integrity and cell viability when DNA replication is perturbed. In Schizosaccharomyces pombe the major effector of the replication checkpoint is the protein kinase Cds1. Activation of Cds1 is known to require the upstream kinase Rad3 and the mediator Mrc1, but the biochemical mechanism of activation is not well understood. We report that the replication checkpoint is activated in two stages. In the first stage, Mrc1 recruits Cds1 to stalled replication forks by interactions between the FHA domain of Cds1 and …

There is significant commercial interest in oil extraction from krill because it is rich in omega-3 polyunsaturated fatty acids (n-3 PUFA) such as eicosapentaenoic (EPA, 20:5n3) and docosahexaenoic (DHA, 22:6n3) acids. The objectives were to determine oil extraction efficiency using different solvent systems and the composition of extracted oil and spent krill following extraction. Extraction efficiency was the highest (P < 0.05) for one-step extraction using freeze-dried krill with 1:12 or 1:30 krill:solvent ratio (w:v) compared to Folch, Soxhlet, and conventional two-step extraction. Extracted oils contained predominantly phospholipids (20–33%), polar non-phospholipids (64–77%), and minor triglycerides (1–3%). Triglycerides contained much less (P …

The theft of property and its associated impact effects many parts of society. For example, a considerable amount of resources are expended in trying to reduce property theft, as such crime engenders both a financial and emotional impact (Grabosky, 1995, p. 1) on those involved. Factors such as fear of crime, increased insurance premiums and victimization are all outcomes of property crime. Much of the past research has focused on the mitigation of such crimes, collectively termed as ‘crime prevention’. Crime prevention are “any actions designed to reduce the actual level of crime and/or the perceived crime” (S.P. Lab, 2010, …
