Eukaryotic cells use autophagy and the ubiquitin-proteasome system (UPS) as their major protein degradation pathways. Whereas the UPS is required for the rapid degradation of proteins when fast adaptation is needed, autophagy pathways selectively remove protein aggregates and damaged or excess organelles. However, little is known about the targets and(More)
The Smg proteins Smg5, Smg6 and Smg7 are involved in nonsense-mediated RNA decay (NMD) in metazoans, but no orthologs have been found in the budding yeast Saccharomyces cerevisiae. Sequence alignments reveal that yeast Ebs1p is similar in structure to the human Smg5-7, with highest homology to Smg7. We demonstrate here that Ebs1p is involved in NMD and(More)
Interactions between proteins are central to most biological processes; consequently, understanding the latter requires identification of all possible protein interactions within a cell. To extend the range of existing assays for the detection of protein interactions, we present a novel genetic screening assay, the cytosolic yeast two-hybrid system(More)
Translation initiation in eukaryotes is accomplished by a large set of translation initiation factors, some of which are regulated by signals monitoring intracellular and environmental conditions. Here, we show that Uri1p is required for efficient translation initiation in budding yeast. Indeed, uri1Delta cells are slow growing, sensitive to translation(More)
As synthetic biology develops into a promising science and engineering field, we need to have clear ideas and priorities regarding its safety, security, ethical and public dialogue implications. Based on an extensive literature search, interviews with scientists, social scientists, a 4 week long public e-forum, and consultation with several stakeholders(More)
As part of the SYNBIOSAFE project, we carried out an open electronic conference (e-conference), with the aim to stimulate an open debate on the societal issues of synthetic biology in a proactive way. The e-conference attracted 124 registered participants from 23 different countries and different professional backgrounds, who wrote 182 contributions in six(More)
Synthetic biology is a new research field that comprises many different projects, approaches and definitions, which, at first glance, do not apparently have much in common. These approaches include the generation of bioengineered bacteria, artificial protocells or synthetic genomes, as well as pure in silico models of protocells or regulatory and metabolic(More)
The difference between a non-living machine such as a vacuum cleaner and a living organism as a lion seems to be obvious. The two types of entities differ in their material consistence, their origin, their development and their purpose. This apparently clear-cut borderline has previously been challenged by fictitious ideas of “artificial organism” and(More)
321 foundations need to invest to turn validated targets and candidate drugs into actual treatments. Our list of likely drug leads and their targets must be validated and extended using additional lines of evidence by computation and, most importantly, wet lab experiments. We are committed to helping other researchers add their protocols and analyses to the(More)
