Linear ubiquitination controls Salmonella growth
May 2017. A team around Ivan Dikic and Mike Heilemann (Chemistry Department, Goethe University) gained unprecedented insight into the mechanism by which cells fight Salmonella infections. Upon intracellular invasion, bacteria are usually rapidly surrounded by a coat of ubiquitin, the function of which remained unclear until now. Combining super-resolution microscopy with cell biological analysis, the researchers now discovered that distinct ubiquitin chains transform the bacterial surface into a molecular signalling platform.

How to brew high-value fatty acids with brewer's yeast
March 2017. NerShort-chain fatty acids are high-value constituents of cosmetics, active pharmaceutical ingredients, antimicrobial substances, aromas or soap. To date, it has only been possible to extract them from crude oil by chemical means or from certain plants, such as coconut, using a complex process. Research groups led by Martin Grininger and Eckhard Boles at Goethe University Frankfurt have now succeeded in producing such fatty acids in large quantities from sugar or waste containing sugar with the help of yeasts. The process is simple and similar to that of beer brewing.

A molecular 'gear shift' in the nervous system
February 2017. Nerve cells communicate via chemical messengers, so-called neurotransmitters (e.g., acetylcholine), which enable a rapid and directed transmission of information. Other messengers used in the nervous system are neurohormones and neuropeptides, which have modulatory functions. The release of such messengers occurs at contact points between neurons, so-called synapses.

New research group joins BMLS
February 2017. In February, Maike Windbergs and her research team joined the BMLS. The group is working on novel drug delivery approaches to treat infectious and inflammatory diseases of epithelial tissues such as the skin and the buccal mucosa. To translate such concepts into the clinical application, a major research focus is on developing preclinical in vitro models as predictive alternative to animal models. According to the 3R-concept (replace, reduce, refine), the group is working on three-dimensional cell cultivates to simulate human tissue in healthy and diseased state. Such models allow for elucidating the due and progress of diseases (e.g. wound infections) as well as testing novel approaches for drug delivery in a pathophysiologically relevant environment. The professorship is embedded into the Faculty 14 (Biochemistry, Chemistry and Pharmacy) of Goethe University and the research focus bridges the interface of fundamental and applied sciences.

New ubiquitin chemistry regulates life processes
December 2016. In the latest issue of Cell, a team around IBC2 director and BMLS member Ivan Dikic reveals molecular details of a novel ubiquitination mechanism that may affect numerous life processes. Earlier this year, U.S. colleagues reported that Legionella enzyme SdeA is capable of catalysing ubiquitination single-handedly. Now, the Frankfurt scientists together with collaborators from the MPI for Biology of Ageing (Cologne) have elucidated the chemistry behind and discovered a hitherto unknown type of linkage between ubiquitin and target proteins. Unlike the conventional ubiquitination reaction, the novel one is NAD-dependent, involving an ADP-ribose intermediate and resulting in the attachment of ubiquitin to substrate serine residues via a phosphodiester bond.

Unveiling the ubiquitin fingerprint induced by Salmonella infection
Salmonella is a Gram-negative bacterium that represents one of the major causes of food-borne diseases in the world and provokes one third of all infections with fatal outcome. This bacterium has evolved several strategies to survive in the human body and to prevent its killing by host immune cells. Its major advantage is its intracellular lifestyle: The bacterium gets enclosed in Salmonella containing vacuoles upon entry into the cell, allowing its replication and propagation. However, also the host cells have developed defence mechanisms against bacterial infection and mark bacterial intruders with ubiquitin resulting in their degradation via the autophagy system (a process called xenophagy). Hence, a cellular invasion by bacterial pathogens can immediately be detected on the molecular level. Read more...

Signal for targeting ΞΒΒ²-barrel proteins to mitochondria identified
A new study, which was published on 27 June 2016 by the journal Nature Communications, reveals that ΞΒΒ²-barrel proteins are targeted to mitochondria by a dedicated ΞΒΒ²-hairpin element and this motif is recognized at the organelle surface by the outer membrane translocase.
Mitochondrial ΞΒΒ²-barrel proteins are synthesized on cytosolic ribosomes and must be specifically targeted to the organelle before their integration into the mitochondrial outer membrane. The signal that assures such precise targeting and its recognition by the organelle remained obscure. A team of scientists from the Goethe University Frankfurt and Tuebingen University has solved the puzzle: a specialized ΞΒΒ²-hairpin motif is this long searched for signal. Read more...

How yeast cells regulate their fat balance -
Cylinder-shaped structures measure saturated and unsaturated fatty acids
Not only humans but also each of their body cells must watch their fat balance. Fats perform highly specialised functions, especially in the cell membrane. A research group at the Buchmann Institute for Molecular Life Sciences (BMLS) of Goethe University in Frankfurt, together with colleagues at the Max Planck Institute of Biophysics, has now discovered how yeast cells measure the availability of saturated and unsaturated fatty acids in foodstuffs and adapt their production of membrane lipids to it. This opens up new possibilities to understand the production and distribution of fatty acids and cholesterol in our body cells and make them controllable in future, report the researchers in the latest issue of the "Molecular Cell" journal.

Uncovering the secrets of root growth
Plants produce new organs throughout their lifespan. It is largely unknown whether this robust post-embryonic organ formation results from stereotypic dynamic processes, in which the arrangement of cells follows rigid rules. A team of scientists from the Universities of Frankfurt and Heidelberg combined modeling with empirical observations of whole-organ development to identify the principles governing lateral root formation using the model plant Arabidopsis.

Roles of autophagy during tumorigenesis
Autophagy can act either as a tumor suppressor or as a survival mechanism for established tumors. To understand how autophagy plays this dual role in cancer, in vivo models are required. By using a highly heterogeneous C. elegans germline tumor, the research group of Christian Pohl in collaboration with the research group of Ivan Dikic could now show that autophagy-related proteins are expressed in a specific subset of tumor cells, the neurons. Moreover, they could demonstrate that inhibition of autophagy impairs neuronal differentiation and results in a shorter life span of animals with tumors. In contrast, induction of autophagy extends life span by impairing tumor proliferation, which also depends on modular changes in transcription networks and mitochondrial metabolism. The findings from this work, recently published in the journal 'Autophagy', suggest that metabolic restructuring, cell-type specific regulation of autophagy and neuronal differentiation play key roles in regulating the growth of heterogeneous tumors.

Protein crystallography without crystals?
December 2015. Structure determination by protein crystallography is limited by the ability of proteins to crystallize. Since many proteins cannot be crystallized, high resolution X-ray structure information is often missing. Masato Akutus from the Buchmann Institute for Molecular Life Sciences has won funding from the Volkswagen Stiftung to develop a novel and rapid approach for structure determination by making use of a molecular framework for protein crystallization. If successful this approach would eliminate the need to crystallize proteins in the conventional way but still provide high-resolution structural information. The molecular framework will act like a molecular sieve, which will trap proteins. It should then be possible to determine the structure of the protein in complex with the sieve. Such a new approach would open a universal, easy, fast and low sample consuming approach that would eliminate the biggest hurdle of protein crystallography.

Model system for the study of heartbeat irregularities
Irregular heartbeat (cardiac arrhythmia) is often associated with mutations in ion channels or other proteins. To enable drug development for distinct arrhythmias, model systems are required that allow the investigation of patient-specific mutations.
A team of scientists led by Alexander Gottschalk at the Goethe Univeristy Frankfurt established a new model system that may allow screening of drug candidates affecting specific mutations in the voltage-gated Ca2+-channel, and permit a better understanding of the effects of distinct mutations on a macroscopic level. Their findings were published on 24 September 2015 in the journal Scientific Reports.
8th Sep 2015 Novel optogenetic Tool for light-dependent generation of the cellular signaling molecule cGMP
Cyclic GMP (cGMP) is an important cellular messenger acting in processes such as visual perception, regulation of blood pressure, induced cell death, but also in regulation of penile erection. For example, the drug Viagra causes accumulation of cGMP in cells. The researche group of Prof. Alexander Gottschalk, together with colleagues from the University of WΞΒΞΒrzburg, was able to establish a novel light-sensitive protein from the aquatic fungus Blastocladiella emersonii as a so-called Ξ²ΒΒΒΒoptogeneticΞ²ΒΒΒΒ tool, which can directly form the messenger cGMP upon illumination of cells expressing it.
7th Sep 2015 BMLS Fundraising Campaign for Refugees
Over 650.000 refugees uprooted by crisis especially in Serbia, Syria, Somalia, Iraq, Eritrea und Bosnian-Herzegovina are expected in 2015 to seek asylum in Germany. It is the cruel truth that more than 2000 refugees were drown during their attempt to flee over the Mediterranean Sea to find shelter and help. The ones which made their exhausting and often very dangerous way to Germany are stranded at initial registration facilities across Germany. Those institutions are currently overstrained by the overwhelming number of refugees. Consequently, many of them Ξ²ΒΒΒΒ including babies, children, old, sick or injured people Ξ²ΒΒΒΒ do not have a place to sleep or to recover from their terrible experiences which lie behind them. More and more cities are starting to build e.g. tent camps for the refugees. But there is a huge lack of simple, material things.

17th Jun 2015 Martin Grininger appointed BMLS Vice Director
Martin Grininger, Lichtenberg Professor of the Volkswagen Foundation and BMLS Group Leader since 2012 has been appointed BMLS Vice Director retroactively as of 1st June 2015 by BMLS Director Enrico Schleiff. Martin Grininger was born 1976 in Linz in Austria. At school he was mainly interested in one thing: sports, especially skiing. Towards the end of his time at school he discovered that he liked chemistry too, so in 1995 he began to study chemistry at the University of Linz. He moved to Graz in 1998 to focus more on organic and biological chemistry and completed his degree with a diploma thesis at the Max- Planck-Institut fΞΒΞΒr Kohlenforschung in MΞΒΞΒhlheim/Ruhr. Martin started his PhD project at the Max Planck Institute for Biochemistry in Martinsried in 2002. After finishing his PhD in 2006 he stayed on at the MPI as project group leader. From 2010 to 2011 he was guest professor at the University of Vienna and in 2012 he became Lichtenberg-Professor of the Volkswagen Foundation at the Goethe University Frankfurt. Skiing remains his hobby. He tries to compensate for the lack of snow in Frankfurt with other sports and activities. The underlying goal of his research is to provide understanding of the functional mechanisms of proteins to finally reprogram their reaction modes. BMLS congratulates Martin Grininger and is looking forward to a successful collaboration.
3rd Jun 2015 When quality control fails
Defects in the quality control systems of cells are often fatal. This is seen in particular in neurodegenerative diseases such as Alzheimer's or Parkinson's. As published in today's online version of Nature, a research team led by Ivan Dikic discovered a new autophagy receptor which plays a central role in cellular quality control. Mutations in this receptor impair its function and cause a hereditary neuropathy named HSAN II. This milestone study not only gives insight into the pathophysiology of a disastrous disease, but also emphasizes the importance of the autophagy network for the wellbeing of cells.

15th Dez 2014 New approach to modifying functional properties of rhodopsin optogenetic tools Ξ²ΒΒΒΒ via the retinal chromophore, not the protein
Since their discovery in 2003, rhodopsin optogenetic tools are widely used in neurobiology. Many variants of these proteins were introduced, all based on mutagenesis or engineering of the protein backbones. In a joint effort, the group of Jana Liewald and Alexander Gottschalk, together with Hegemann (Berlin), Fiala (GΞΒΞΒttingen) and Trauner (Munich) have developed a novel approach to alter the functional properties of rhodopsin optogenetic tools, namely by modifications of the retinal chromophore. Synthetic retinal analogs were introduced into Channelrhodopsin-2 (ChR2) or other rhodopsin tools in C. elegans, Drosophila and human cells, to change the light sensitivity, photo cycle kinetics and color spectrum of the optogenetic actuators. The work is going to be published in Nature Communications on Monday, 15th December, 2014. Read more

25th Feb 2014 New piece in the puzzle of neuronal communication.
Detailed knowledge of the mechanisms that underlie neuronal communication is essential to better understand brain function and pathological conditions. Neurons can modulate their signal input not only by altering the area covered by their dendritic trees, but also by adapting the strength of their synapses. Regulation of cargo transport via adaptor molecules is essential for neuronal development. However, the role of PDZ scaffolding proteins as adaptors in neuronal cargo trafficking is still poorly understood. Read more...
10th Feb 2014 BMLS scientists Deepika Singh and Christian Pohl uncover a biomechanical mechanism for embryonic patterning.
Early embryos need to generate a specific coordinate system to develop properly. In the last issue of Developmental Cell, BMLS scientists Deepika Singh and Christian Pohl now uncover a biomechanical mechanism that helps to form one axis in this coordinate system. This mechanism uses a remnant of cell division to orient cells along this axis. Link to publication
Just before Christmas three group leaders signed their contracts for starting their first independent groups at BMLS. Dr Anja Bremm (left) who received a prestigious Emmy Noether Fellowship from the German Research Foundation (DFG), Dr Masato Akutsu (second from left) who will be heading a group endowed by the Leibniz Prize awarded to Ivan Dikic (right) by the DFG, and Dr Kathi Zarnack (third from left) who will be funded through the LOEWE program 'Ubiquitin networks'. Both Kathi Zarnack and Masato Akutsu will also be supported by a donation from the Buchmann Foundation. All three will start their groups in 2014, Anja Bremm mainly concentrating on cellular signaling, Masato Akutsu strengthening the structural biology platform, and Kathi Zarnack establishing the first bioinformatics group.
In collaboration with Katrin Rittinger at the MRC-NIMR in London, the Dikic group solved a molecular puzzle about the formation of specific Ubiquitin chains. In the current issue of Nature, they report the crystal structure of the catalytic core of HOIP, the critical enzymes involved in forming linear (Met1-linked) Ubiquitin chains. These chains are important regulators of cellular signalling, and knowing the molecular structure of the complexes involved is an important step forward to understanding how these pathways control innate immunity and inflammation.

New target for tumor therapy - Nature letter: When drugs could permanently disrupt the pathological formation of blood vessels
As from a specific size, solid tumors form a capillary network of blood vessels that grows along with them. One therapy approach is to suppress growth of blood vessels to starve the tumor. Drugs so far used in the clinic block the vessel growth factor VEGF (Vascular Endothelial Growth Factor). However, there is growing evidence that tumors can avoid or become resistant to this blockade. Little is known about how this takes place since the sprouting of blood vessels (angiogenesis) is not understood in detail yet.

CEF successful in new round of Excellence Initiative
For research focused on cancer it is important to understand the regulation of growth factors which are responsible for the proliferation and differentiation of cells. Growth hormones signal to the cell via receptors that are positioned in the cell membrane. When an extracellular growth factor docks on its receptor, the membrane area surrounding it invaginates and gets cut off. Enclosed in a small bubble (vesicel) inside the cell the receptor is transported to other membrane enclosed compartments where it can signal to the cell to proliferate or to migrate.
