Bioinformatics Course at the University of Regensburg



From October 10th to 14th 2016, a methods course on ‘Analysis of NextGen RNA-Seq data for expression profiling and protein binding RNAs‘ will take place here in Regensburg. Insightful lectures will be deliverd by reknown experts in the field, including (in alphabetical order) Simon Anders (FIMM Helsinki), Markus Hafner (NIAMS/NIH Bethesda), Steve Hoffman (University of Leipzig), Stefan Kirsch (Fraunhofer  ITEM, Regensburg), Charlotte Soneson (University of Zurich), Rainer Spang (University of Regensburg), Nicholas Strieder (University of Regensburg), and Grischa Toedt (EMBL Heidelberg). After the lectures, there will be ample time for hands-on training allowing the participants to gain some practical experience with the latest computational approaches. If you are interested in participating, please register before July 13th.

The course is generously supported by the Graduate Research Academy RNA Biology of the Collaborate Research Center SFB960 ‘Ribosome formation: principles of RNP biogenesis and control of their function’.

August 2nd, 2016 – Guest speaker: Mandy Jeske, EMBL Heidelberg

Oskar localizationSave the date! On August second 5p.m. in H53, Mandy Jeske from the EMBL in Heidelberg will give a talk entitled: Exploring molecular mechanisms in the germ plasm.

Germ cells are an integral part of sexual reproduction. To segregate the germline from soma, during early development many animals assemble a specialized cytoplasm, which is called germ plasm. The molecular mechanisms that take place in and define the germ plasm are poorly understood.

In her talk Mandy Jeske from the EMBL in Heidelberg will discuss molecular functions of the Drosophila germ plasm nucleation protein Oskar. She will present the recently solved crystal structures of Oskar and discuss activities of previously uncharacterized protein domains. Furthermore, she will address the molecular functions of Vasa, a germ-line specific DEAD-box RNA helicase involved in the secondary piRNA pathway, and how a novel class of protein domains regulates Vasa’s enzymatic activity.

We are very much looking forward to Mandy’s visit, a fascinating talk and exciting discussions!

July 21st, 2016 – Guest speaker: Andrea Pauli, IMP Vienna

Andrea-PauliMark your calendar! On July 21st, Andrea Pauli from the Research Institute of Molecular Pathology (IMP), Vienna, Austria, will visit the University of Regensburg. Her major research interest is the function of short open reading frames in zebrafish development.

Recent findings have indicated that eukaryotic translation is far more complex than anticipated with the frequent translation of short open reading frames that were previously overlooked. This ‘pervasive translation’ includes regions that are predicted to encode short, conserved proteins, while other translated regions lack signatures of protein conservation and might serve gene-regulatory functions. This raises two important questions: what is the role of the translated regions in the regulation of gene expression, and what are the functions of the newly discovered short proteins/petides? In her talk entitled ‘Found in translation: from genomics to novel gene functions in zebrafish’ (2p.m. in H53), Andrea will share exciting insights into the functions and regulatory principles of these newly discovered short translated open reading frames (ORFs) employing zebrafish embryogenesis as a model system.

Review article: The expanding universe of ribonucleoproteins

Soon a special issue with focus on ‘RNA biology in physiology and disease’ will be published by the European Journal of Physiology (Pflügers Archiv). Together with our colleagues Benedikt Beckmann (IRI for the Life Sciences, Humboldt University Berlin) and Alfredo Castello (University of Oxford) we have contributed a review article entitled: The expanding universe of ribonucleoproteins – of novel RNA-binding proteins and unconventional interactions.

We focus on the recent advances in the identification of novel RNA-binding proteins (RBPs) and the unexpected finding that many of the novel RBPs do not contain identifiable RNA-binding domains (RBDs), raising the question of how they interact with RNA. It is surprising that despite the many functions that have been attributed to RNA, our understanding of ribonucleoproteins (RNPs) is still mostly governed by a rather protein-centric view, leading to the idea that proteins have evolved to bind to and regulate RNA and not vice versa. However, RNPs formed by an RNA-driven interaction mechanism (‘RNA-determined RNPs’) are abundant and offer an alternative explanation for the surprising lack of ‘classical’ RBDs in many RNA-interacting proteins (which we discuss in detail in the review article).

Nobel laureate Randy Schekman talks about unconventional secretion of protein and RNA

Photos courtsey of Andreas FuchsStudents of the Regensburg International Graduate School for Life Sciences (RIGeL) invited Randy Schekman (UC Berkeley) for an honorary lecture to Regensburg. In 2013, together with his colleagues James Rothmann (Yale University) and Thomas Südhof (Stanford University), Randy received the Nobel Prize for Medicine for his groundbreaking work on cellular trafficking. It was an exciting event with great science and lots of fun! (Photos courtsey of Andreas Fuchs)

Meeting of the DFG Research Unit 2333 ‘Macromolecular complexes in mRNA localization’ (FOR2333)

FOR2333LogoThe first meeting of the DFG Research Unit 2333 (FOR2333) took place on March 1st and 2nd in the beautiful town of Blaubeuren, famous for its resurgence the ‘Blautopf’ that feeds the Danube river.  FOR2333 receives funding from the DFG since beginning of 2016 to foster multidisciplinary research aiming to understand principles of gene regulation by directional mRNA transport and local translation. Unfortunately our application to become part of this exciting research team was not successful but nonetheless we were invited to participate in this wonderful meeting packed with talks about exciting research and novel findings. We are extremely happy for this opportunity and we are looking forward to continuing our collaborations with several groups of the consortium.

New colleague in the lab: Andreas Horn

AndreasThe new year has just started and already there are some great news: Andreas Horn joined the lab as a PhD student! His PhD project will focus on a novel strategy that we have recently developed which allows to map protein-RNA interaction with high resolution in a parallel fashion. Welcome to the lab!
