In collaboration with Abberior Instruments, visitors to JPK's applications facility will be able to see STED capability demonstrated in conjunction with the NanoWizard® AFMs. Following collaboration with Abberior Instruments (Göttingen, Germany), visitors to JPK's facility in Berlin will now be able to see a demonstration of STED capability. JPK and Abberior have launched a program to demonstrate the combined features of their NanoWizard® AFMs and STEDYCON systems respectively. Situated in the applications laboratories under the management of JPK's Dr Heiko Haschke, visitors will be able to see real-time demonstrations of simultaneous confocal, STED and AFM techniques. Co-founded by the 2014 Nobel Prize winner in Chemistry, Professor Stefan Hell, Director of the Max Planck Institute for Biophysical Chemistry, and co-workers from his group in Göttingen and at the German Cancer Research Institute in Heidelberg, Abberior Instruments was founded in 2012 to offer patent-protected, novel superresolution microscopes for general applicability in the life sciences. The company has developed a completely new instrument: the ultimate compact STED plus confocal microscope known as STEDYCON. This converts a conventional epifluorescence microscope into a powerful multi-color confocal and STED system. This is the perfect complementary partner for the NanoWizard® AFM systems to deliver correlative microscopy on a new level, one which is readily accessible to users from multiple background & disciplines. “It is a unique opportunity to combine the advantages of superresolution light microscopy down to the macromolecular level with the nanometer precise manipulation and imaging skills of JPK’s AFM in a correlative, real-time STED plus AFM setup”, said Dr Matthias Reuss, Abberior Instruments Head of Marketing and Sales. ”I am very excited to have the first system in the world integrating the new Abberior STEDYCON into the JPK SPM families. Due to the novel STEDYCON design and interface and the latest JPK ease-of-use strategy, complex STED-AFM experiments have become a routine in our laboratories. The Abberior STEDYCON and the latest JPK NanoWizard® AFMs with their fast AFM technology also allows scientists to investigate nanomechanical and super-resolution optical phenomena at similar temporal and spatial resolution.” said Dr Heiko Haschke, head of applications, software and customer support at JPK Instruments. “We are confident that with this system we can finally determine the mechanical properties of actin filaments and microtubules in living cells by manipulating them with the AFM tip on the nanometer scale while simultaneously observing them with STED microscopy.” Dr Haschke added.

Calcium-dependent exocytosis of synaptic vesicles mediates the release of neurotransmitters. Important proteins in this process have been identified such as the SNAREs, synaptotagmins, complexins, Munc18 and Munc13. Structural and functional studies have yielded a wealth of information about the physiological role of these proteins. However, it has been surprisingly difficult to arrive at a unified picture of the molecular sequence of events from vesicle docking to calcium-triggered membrane fusion. Using mainly a biochemical and biophysical perspective, we briefly survey the molecular mechanisms in an attempt to functionally integrate the key proteins into the emerging picture of the neuronal fusion machine. © 2012 Macmillan Publishers Limited.

Progress in Lipid Research | Year: 2011

Intracellular lipid droplets have long been misconceived as evolutionarily conserved but functionally frugal components of cellular metabolism. An ever-growing repertoire of functions has elevated lipid droplets to fully-fledged cellular organelles. Insights into the multifariousness of these organelles have been obtained from a range of model systems now employed for lipid droplet research including the fruit fly, Drosophila melanogaster. This review summarizes the progress in fly lipid droplet research along four main avenues: the role of lipid droplets in fat storage homeostasis, the control of lipid droplet structure, the lipid droplet surface as a dynamic protein-association platform, and lipid droplets as mobile organelles. Moreover, the research potential of the fruit fly model is discussed with respect to the prevailing general questions in lipid droplet biology. © 2011 Elsevier Ltd. All rights reserved.

The fruit fly Drosophila melanogaster is an emerging model system in lipid metabolism research. Lipid droplets are omnipresent and dynamically regulated organelles found in various cell types throughout the complex life cycle of this insect. The vital importance of lipid droplets as energy resources and storage compartments for lipoanabolic components has recently attracted research attention to the basic enzymatic machinery, which controls the delicate balance between triacylglycerol deposition and mobilization in flies. This review aims to present current insights in experimentally supported and inferred biological functions of lipogenic and lipolytic enzymes as well as regulatory proteins, which control the lipid droplet-based storage fat turnover in Drosophila.

The concept of a readily releasable pool (RRP) of synaptic vesicles has been used extensively for the analysis of neurotransmitter release. Traditionally the properties of vesicles in such a pool have been assumed to be homogeneous, and techniques have been developed to determine pool parameters, such as the size of the pool and the probability with which a vesicle is released during an action potential. Increasing evidence, however, indicates that vesicles may be quite heterogeneous with respect to their release probability. The question, therefore, arises: what do the estimates of pool parameters mean in view of such heterogeneity? Here, four methods for obtaining pool estimates are reviewed, together with their underlying assumptions. The consequences of violation of these assumptions are discussed, and how apparent pool sizes are influenced by stimulation strength is explored by simulations. Synaptic vesicles are released by action potentials in an all-or-nothing manner. Erwin Neher explores how estimates for the number of release-ready vesicles and their release probability, as obtained by commonly used analysis methods, are influenced by the fact that "pools" of vesicles are not homogeneous. © 2015 Elsevier Inc.

Pre-mRNA splicing is catalyzed by the spliceosome, a multimegadalton ribonucleoprotein (RNP) complex comprised of five snRNPs and numerous proteins. Intricate RNA-RNA and RNP networks, which serve to align the reactive groups of the pre-mRNA for catalysis, are formed and repeatedly rearranged during spliceosome assembly and catalysis. Both the conformation and composition of the spliceosome are highly dynamic, affording the splicing machinery its accuracy and flexibility, and these remarkable dynamics are largely conserved between yeast and metazoans. Because of its dynamic and complex nature, obtaining structural information about the spliceosome represents a major challenge. Electron microscopy has revealed the general morphology of several spliceosomal complexes and their snRNP subunits, and also the spatial arrangement of some of their components. X-ray and NMR studies have provided high resolution structure information about spliceosomal proteins alone or complexed with one or more binding partners. The extensive interplay of RNA and proteins in aligning the pre-mRNA's reactive groups, and the presence of both RNA and protein at the core of the splicing machinery, suggest that the spliceosome is an RNPenzyme. However, elucidation of the precise nature of the spliceosome's active site, awaits the generation of a high-resolution structure of its RNP core. © 2011 Cold Spring Harbor Laboratory Press.

Accurate exon-intron structures are essential prerequisites in genomics, proteomics and for many protein family and single gene studies. We originally developed Scipio and the corresponding web service WebScipio for the reconstruction of gene structures based on protein sequences and available genome assemblies. WebScipio also allows predicting mutually exclusive spliced exons and tandemly arrayed gene duplicates. The obtained gene structures are illustrated in graphical schemes and can be analysed down to the nucleotide level. The set of eukaryotic genomes available at the WebScipio server is updated on a daily basis. The current version of the web server provides access to ∼3400 genome assembly files of >1100 sequenced eukaryotic species. Here, we have also extended the functionality by adding a module with which expressed sequence tag (EST) and cDNA data can be mapped to the reconstructed gene structure for the identification of all types of alternative splice variants. WebScipio has a user-friendly web interface, and we believe that the improved web server will provide better service to biologists interested in the gene structure corresponding to their protein of interest, including all types of alternative splice forms and tandem gene duplicates. WebScipio is freely available at http://www.webscipio.org.

Trends in Cell Biology | Year: 2010

Fusion of Golgi-derived COP (coat protein)-I vesicles with the endoplasmic reticulum (ER) is initiated by specific tethering complexes: the Dsl1 (depends on SLY1-20) complex in yeast and the syntaxin 18 complex in mammalian cells. Both tethering complexes are firmly associated with soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) at the ER. The structure of the Dsl1 tethering complex has been determined recently. The complex seems to be designed to expose an unstructured domain of Dsl1p at its top, which is required to capture vesicles. The subunit composition and the interactions within the equivalent mammalian complex are similar. Interestingly, some of the mammalian counterparts have additional functions during mitosis in animal cells. Zw10, the metazoan homolog of Dsl1p, is an important component of a complex that monitors the correct tethering of microtubules to kinetochores during cell division. This review brings together evidence to suggest that there could be common mechanisms behind these different activities, giving clues as to how they might have evolved. © 2010 Elsevier Ltd.

In all contemporary organisms, the active site of the ribosome-the peptidyl transferase center-catalyzes two distinct reactions, peptide bond formation between peptidyl-tRNA and aminoacyl-tRNA as well as the hydrolysis of peptidyl-tRNA with the help of a release factor. However, when provided with appropriate substrates, ribosomes can also catalyze a broad range of other chemical reaction, which provides the basis for orthogonal translation and synthesis of alloproteins from unnatural building blocks. Advances in understanding the mechanisms of the two ubiquitous reactions, the peptide bond formation and peptide release, provide insights into the versatility of the active site of the ribosome. Release factors 1 and 2 and elongation factor P are auxiliary factors that augment the intrinsic catalytic activity of the ribosome in special cases. © 2013 Elsevier Ltd.
