CANCELED: EMBO Practical Course on Measuring Translational Dynamics by Ribosome Profiling

It is with heavy heart that we have to inform you that EMBL Heidelberg and the scientific organisers have decided to postpone the EMBO Practical Course: Measuring Translational Dynamics by Ribosome Profiling 2020.

We have taken this difficult decision in order to better play our part in reducing the impact and spread of the novel coronavirus and also in recognition of the fact that many of our speakers and participants are currently finding it difficult to travel.

The new date for this course is still under discussion and will be communicated once it has been agreed.

February 25th, 2020 – Guest Speaker: Sebastian Leidel

tRNA modifications – Connecting translation dynamics to cellular quality control

On february 25th, 2020, at 5 p.m., Sebastian Leidel from the University of Bern will give a talk in H53. Sebastian and his lab have pioneered the use of ribosome profiling to understand the importance of tRNA modifications in translation.

tRNAs are key players in mRNA translation linking amino acids to a specific codon sequence. Interestingly, tRNA molecules carry a plethora of chemical modifications of their nucleotides, which are posttranscriptionally introduced by many different enzymatic pathways. Even though huge progress has been made, it is still unclear how most of these tRNA modifications contribute to cellular function. This is of particular importance as GWAS studies have linked different modification pathways to a number of degenerative diseases and cancer. New technologies explored by Sebastian and his lab have provided novel insights into this exciting research field.

We are looking forward to seeing you on Tuesday for an evening of exciting science!

Methods course on RNP analyses – from ensembles to single molecules

From October 8th to 10th 2018, a hands-on methods course took place at the University of Regensburg, aimed at training PhD students in the latest methods of ribonucleoprotein (RNP) analysis. Topics included the quantification of protein-RNA interactions, single molecule analyses of RNPs by fluorescence resonance energy transfer (FRET) or fluorescence in situ hybridization (FISH), RNA structure probing, and comprehensive capture of RNA-binding proteins by interactome profiling from cultured cells. The course attracted PhD students from labs around the globe, some travelling from as far as Canberra, Australia, to get insight in and training on a variety of biophysical and biochemical methods. The design of the course was also aimed at fostering interactions between the participants, allowing them to build networks with peers working on related topics. Besides the lectures and the practical hands-on training, it was particularly the vivid and intense discussions among the participants that made this course a big success.

We are extremely grateful for the support of many expert speakers and trainers that delivered lectures on the latest methodological developments and that supervised the experimental work. In particular we want to thank the invited speakers from industry and academia that travelled to Regensburg to provide expert guidance: Rastislav Horos (European Molecular Biology Laboratory, EMBL, Heidelberg), Agatha Korytowski (Malvern Panalytical), Stefanie Nunes Rosa (Swedish University of Agricultural Sciences, Uppsala), Joel Perez-Perri (EMBL Heidelberg), Bruno Sargueil (CNRS/Paris Descartes University), and Ralf Seidel (Peter Debye Institute for Soft Matter Physics, Universität Leipzig).

The course was organized by the Graduate Research Academy RNA Biology of the Collaborative Research Centre 960 (SFB960, Ribosome formation: principles of RNP biogenesis and control of their function) that also provided financial support.

Honorary Doctorate for Thomas Cech

A particular highlight is coming up next week: Prof Thomas Cech will be awarded a honorary doctorate by the University of Regensburg. Tom Cech, now Professor at the University of Colorado at Boulder and director of the BioFrontiers Institute, was awarded the Nobel Prize in chemistry in 1989 jointly with Sidney Altman for the discovery of the catalytic activity of RNA. His revolutionary discovery of self-splicing in Tetrahymena thermophila radically changed the way we were thinking about RNA – what was previously considered a mere carrier of genetic information turned out to play the key function in fundamental biological processes. Exemplarily, protein synthesis is catalyzed by the RNA moiety of the large ribosomal subunit which promotes the peptidyl transfer reaction by which peptide bonds are formed between amino acids. His discovery also had a huge impact on my own scientific career and convinced me that RNA is the most interesting biomolecule to study. I am very much looking forward to the Symposium on Monday, October 22nd (starting 3:30p.m. in lecture hall H51) and to finally get the opportunity to meet Tom Cech in person!

From Ensembles to Single-Molecule Analysis

Mark your calendars! From October 8th to 12th the Graduate Research Academy RNA Biology of the Collaborative Research Center 960 (SFB960 – Ribosome formation: principles of RNP biogenesis and control of their function) is hosting a practical course on modern methods for the analysis of ribonucleoproteins (RNPs). Diverse topics will be covered ranging from biophysical analyses (such as isothermal calorimetry and thermophoresis), single-molecule RNP studies (single-molecule FRET and FISH), RNA structure probing and the latest RNA interactome capture methodology. In the morning, renowned experts will deliver lectures to introduce the individual topics, followed by hands-on experimentation in the afternoon. All lectures are open to the public, so even if you didn’t register, you certainly don’t want to miss out on the exciting talks by Rastislav Horos (EMBL Heidelberg), Agatha Korytowski (Malvern Panalytical GmbH), Stefanie Nunes Rosa (Swedish University of Agricultural Sciences, Uppsala), Joel Perez-Perri (EMBL Heidelberg), Bruno Sargueil (CNRS/ Paris Descartes University), and Ralf Seidel (Universität Leipzig)!

Good News: Jan’s Habilitation is almost finished…

On Wednesday, November 29th, Jan successfully finished the final phase of his Habilitation by delivering a lecture in front of the entire faculty.

`I want to thank everybody who supported me along the way, in particular my lab and the colleagues in the Biochemistry I department of the University of Regensburg, especially Gunter Meister. Also without the help of our colleagues in the Collaborative Research Center 960 (Sonderforschungsbereich SFB960), our excellent collaborators, and the funding (provided by BioSysNet, DFG and BMBF) we would not have succeeded with our scientific work that was an essential part of the Habilitation.´

It is a german tradition to prepare a handcrafted hat as a present for candidates that have just obtained their doctoral degree. Jan also got a super-cool Drosophila hat for his Habilitation – thank you to everybody who helped crafting it!

Review on function of Drosophila Sex-lethal

Good news! We are happy to announce that our review on the function of the Drosophila RNA-binding protein Sex-lethal (Sxl) was recently accepted. Sxl is particularly interesting: it is a rather small RNA-binding protein with a simple architecture, nonetheless it engages in the regulation of multiple aspects of gene expression to direct female development. The review is open access and can be downloaded here. Let us know what you think about it!

Bioinformatics Course – A combination of excellent speakers and target-oriented hands-on training

A very well organized and extremely helpful course on RNA-Seq analysis featuring top-notch speakers and experts in the field

– that is how one of the participants summarized the recent bioinformatics course on ‘Analysis of NextGen RNA-Seq data for expression profiling and protein-binding RNAs’ that took place from October 10th to 14th at the University of Regensburg. The Graduate Research Academy RNA Biology hosted several renowned experts in the field that delivered fascinating, public lectures statement-franziaddressing state-of-the-art methods for gene expression profiling and RNP analysis. Afterwards 18 selected participants had the opportunity for some hands-on training on actual datasets. We are happy that so many interested students from seven different universities joined us. And apparently, according to the feedback we got, for the participants the course really did make a difference:

with the combination of excellent speakers and target-oriented hands-on training, this one-week course increased my knowledge on current NGS tools and enabled me to analyze my own datasets

October 20th, 2016 – Guest speaker: Dierk Niessing

Dierk-NiessingMark your calendar – there will be an exciting talk on October 20th! Dierk Niessing (affiliated with both the Biomedical Center of the Ludwig-Maximilians-University Munich and the Institute of Structural Biology of the Helmholtz Zentrum Munich) will present fascinating data on how RNPs assemble and how mRNA localization is achieved.

In eukaryotes asymmetric localization of mRNAs and their local translation is a universal mechanism to generate cellular asymmetry. It is required for diverse processes such as embryogenesis, stem cell division and differentiation of somatic cells. For localization the transcripts are selectively recognized by motor-protein containing particles and actively transported along the cytoskeleton. Despite its importance, the molecular basis of this spatial and temporal control of gene expression is not well understood. The Niessing lab took advantage of the fact that mRNA localization in budding yeast involves considerably fewer core factors than in higher eukaryotes. In S.cerevisiae the ASH1 mRNA and about 30 other transcripts are actively transported from the mother to the daughter cell by a myosin-containing complex. At the tip of the daughter cell ASH1 mRNA then becomes locally translated.

Employing biochemical, biophysical and structural approaches, Dierk’s lab has studied in molecular detail the assembly of all core components of the ASH1 mRNA-transport complex. Moreover, they have succeeded to in vitro reconstitute transport complexes, motile particles with the size of about 1mDa, and characterized key features of their biogenesis and activation. Together these insights serve as one of the best-understood examples of how cells generate cellular asymmetry on the molecular level.

Dierk is a full professor at the Biomedical Center of the Deptartment of Cell Biology at the Ludwig-Maximilians-University Munich and deputy director of the Institute of Structural Biology of the Helmholtz Zentrum München. He is also the speaker of the recently funded DFG Research Unit FOR2333 ‘Macromolecular Complexes in mRNA Localization’, a multidisciplinary research consortium that addresses principles of gene regulation by directional RNA transport and local translation.
