SUMO-mediated control of a histone-modifying complex
The group of Stefan Müller unraveled a novel facet of SUMO-regulated gene expression. They discovered that the SUMO-specific isopeptidase SENP3 is needed for proper activity of histone-modifying MLL1/2 complexes. Removal of SUMO2/3 from the MLL1/2 subunit RbBP5 is required for the activation of a subset of HOX genes, including the regulator of osteogenic differentiation DLX3. The importance of this pathway for cell differentiation was demonstrated in a human stem cell model. The paper by Nayak et al. was published online in Molecular Cell on June, 12.

HFSP Program Grant for IBC2
The International Human Frontier Science Program (HFSP) Organization announced this year's winners of the competition for one of the prestigious HFSP research grants. Amongst the awardees is the Dikic group, who together with the Sidhu group (Canada), the Komatsu group (Japan) and the Sander group (U.S.) will receive 1,35 M USD for the next 3 years. "This award considerably pushes autophagy research in Frankfurt, especially because it funds one of our most innovative projects. Within the next 3 years, we expect to gain a lot of knowledge about molecular targeting of the autophagy network", says Ivan Dikic, IBCII director. Read more

The control of signaling in immunity and inflammation
The groups of Ivan Dikic and Masato Akutsu have moved closer in understanding how a novel form of protein modification, the linear ubiquitination, controls central pathways of immunity and inflammation. In a collaborative effort, they showed that the two enzymes responsible for assembling and disassembling linear ubiquitin chains are contained in one complex. By structural analysis, they managed to decipher the molecular details of the interaction between these two key enzymes and were able to show how the opposing activities of the complex are controlled. Their results are published in the current edition of Molecular Cell online.

Deciphering the molecular mechanisms behind the cell's power packs
Complex I is the largest enzyme of the respiratory chain, a fundamental metabolic pathway operating to supply the cell with energy. Dysfunction of complex I causes numerous neuromuscular and neurodegenerative diseases in humans. Combining biochemical and structural evidence the Zickermann group now succeeded in shedding light on the essential role of accessory subunit NB4M (NDUFA6/LYRM6) for complex I function. The results are published in the current early edition of the journal PNAS (Angerer et al., doi: 10.1073/pnas.1322438111).

IBC2 and BMLS appointing two new group leaders
In a joint effort, IBC 2 and the Buchmann Institute (BMLS) recruited two new group leaders: Dr Anja Bremm (left) who received a prestigious Emmy Noether Fellowship from the German Research Foundation (DFG) and Dr Masato Akutsu (right) who will be heading a group endowed by the Leibniz Prize awarded to Ivan Dikic by the DFG. Both groups will be located in the BMLS on Riedberg campus, Anja Bremm mainly concentrating on cellular signaling, and Masato Akutsu strengthening the structural biology platform.

Structure of HOIP catalytic core solved
In collaboration with Katrin Rittinger at the MRC-NIMR in London, the Dikic group solved another 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.

Who's most cited of them all?
In its recent issue, Laborjournal (LJ) publishes a citation analysis in the field of cell biology covering the period from 2007 to 2010. Instead of asking the mirror, LJ searched the database "Web of Science" for authors based in Germany, Austria and Switzerland. Amongst the Top 5: IBC2 director Ivan Dikic with 1886 citations of 35 articles. One article from the Dikic lab made it under the Top 10 of most cited articles: the report about a role for the protein NBR1 in autophagy , published by Kirkin and collaborators 2009 in the journal Molecular Cell.

A novel mechanism regulating SUMO-dependent protein networks.
The covalent attachment of the ubiquitin-like modifier SUMO to proteins serves an important mechanism for the control of protein-protein interactions. This is generally mediated via recognition of a SUMO-conjugate by an interaction partner that contains a specific SUMO interaction module, termed SIM (SUMO interaction motif). A major question is how the dynamics of SUMO/SIM interactions are regulated. Recent work done by Rebecca Ullmann in Stefan Muller's group together with co-workers from the Lombardi Cancer Center in Washington now uncovered an acetyl-dependent switch that determines the selectivity and dynamics of SUMO-SIM interactions (Molecular Cell, online May 10, 2012). In this context they show that acetylation of SUMO within a basic interface prevents binding to SIMs in PML, Daxx, and PIAS. One the other hand, acetyl-SUMO specifically binds to the Bromodomain of the co-activator p300. This acetyl-dependent switch of SUMO-mediated protein interactions attenuates SUMO-regulated gene silencing and affects the assembly of PML nuclear bodies. This work thus unravels a novel interplay of post-translational modifications that expands the regulatory repertoire of SUMO signaling.

ERC Starting Grant awarded to Dr. Christian Behrends:
The ERC approved funding for his proposal on Xenophagy and bacterial avoidance (XABA). Briefly, microbial pathogens that successfully parasitize eukaryotic cells have evolved to evade autophagic microbial defenses (xenophagy) and subvert the host autophagic responses for their own survival and/or growth.
