SFB 1551 Seminar Series Event - Dr. Davide Mercadante
2026-01-22 10:30 - 11:30 UTC | Biocenter I, EG 00.187, Hanns-Dieter-Hüsch-Weg 15, Mainz
“Functional advantages of protein structural disorder as revealed by integrative biophysics”
Dr. Davide Mercadante (School of Chemical Sciences, The University of Auckland, Auckland, New Zealand)
Summary:
Since the discovery that protein structural disorder holds functional relevance intrinsically disordered proteins (IDPs) have become a cornerstone of biophysics.
Characterized by extremely high dynamics, IDPs are elusive by nature and traditional structural biology techniques remain largely uncapable of providing an exhaustive understanding of their behavior.
However, the qualitative and quantitative integration of computational experimental techniques well-versed to assess protein dynamics, thus provides a powerful framework to elucidate IDPs’ dynamics-driven functions. This talk will overview how the integration of biophysical approaches within the experimental and computational realms has favored the discovery of new functional paradigms empowered by protein disorder. 1–5 I will showcase how simulations employing all-atom or coarse-grained modelling of protein chains, can help linking the conformational behavior of IDPs to their ensemble-based function: and how it can be possible to obtain experimentally sound protein ensembles from coarse grained protein models, through a direct integration of NMR observables into simulations. 6,7

SFB 1551 Seminar Series Event - Dr. Sergio Cruz-Leon
2025-12-05 09:00 - 10:00 UTC | BZ2 Room 02.721 (2nd floor), Hans-Dieter-Hüsch-Weg 17, Mainz, Germany
“Bridging cellular 3D imaging with physics-based simulations for biological discovery”
Dr. Sergio Cruz-Leon (MPI Biophysics, Frankfurt)
Summary:
Cellular function is governed by the structure, location, and dynamics of its densely packed molecular machines. Cryo-electron tomography (cryoET) captures 3D snapshots of intact cells at near molecular resolution. However, extracting reliable molecular identities and interactions from tomographic data remains challenging.
I will show how high-confidence 3D template matching (hcTM) for cryoET [1], coupled with multiscaling, enables us to model and simulate biological landscapes directly from cryoET data [1-3]. hcTM reliably localizes a wide range of macromolecular complexes in crowded cytoplasm and nuclei, producing spatial maps that are the basis to build simulation-ready models of subcellular environments.
Using this framework, we uncovered vault particles loaded with ribosomal cargo [1] and the unexpected ‘cracking’ of the nuclear pore complex (NPC) during HIV passage [2], and resolved the molecular architecture of human chromatin in situ [3]. We then applied it to an autophagy-related condensate directly in cells, demonstrating that a single amino-acid substitution strengthens intermolecular interactions, drives a liquid-to-glass mesoscale transition, and abolishes autophagic clearance. We thereby link a molecular alteration to changes in condensate material properties and biological function.
Integrating in situ imaging with multiscale simulation provides a pipeline for visual proteomics and sets the stage for simulating cellular processes in their native context.

Keywords: Visual proteomics, cryoET, high-confidence template matching, multi-scale simulations, HIV, chromatin, biomolecular condensates.

Weak Non-Covalent Interactions in Biopolymer and Synthetic Supramolecular Assemblies
This lecture introduces the basic principles that define modern supramolecular chemistry through a historical and conceptual overview of non-covalent interactions. We will examine the nomenclature and evolution of key interaction types, including hydrogen bonding, Coulomb interactions, π–π stacking and related interactions in aromatic systems. Emphasis will be placed on understanding how enthalpic and entropic contributions govern the formation, strength, and selectivity of supramolecular assemblies. Finally, we will explore the crucial role of the solvent environment—highlighting solvation and solvophobic effects in (macro)molecular recognition and self-assembly. These elements provide a framework for analyzing and designing non-covalent systems across chemistry, biology, and materials science.

Partners in time – the RNA interactome of plant RNA-binding proteins
RNA-based regulation plays a key role in plant responses to endogenous cues and environmental stimuli. To provide insights into in vivo RNA-protein interactions shaping the transcriptome, we improved our previous protocol for individual nucleotide resolution crosslinking and immunoprecipitation and, in collaboration with Kathi Zarnack, established a bioinformatics pipeline to evaluate iCLIP-seq data (plant iCLIP2). We comprehensively profiled the binding landscape of Arabidopsis thaliana glycine-rich RNA binding protein 7 implicated in different steps of RNA processing and function. In the compendium of target transcripts, we delineated motifs preferentially associated with binding sites. Orthogonal transcriptomic data obtained from loss-of function mutants and plants overexpressing the RNA binding proteins provided insights into the mode of action how AtGRP7 affects its target transcripts. In particular, in collaboration with Martin Crespi we pursue the idea that long noncoding RNAs interacting with AtGRP7 and the splicing regulator NSRa serve as regulators of alternative splicing. In turn, we developed single mRNA interactome capture and identified ALBA4, a protein interacting with m6A readers, as an AtGRP7 interactor. Collectively, our data begin to shed light on the organisation of networks in posttranscriptional regulation in Arabidopsis.

When Discovery Isn’t Enough: Why It Matters to Communicate Your Science Well
Imagine making a discovery that could change your field—only to watch it vanish into obscurity because no one quite “got it.” This happens more often than we’d like to admit. Breakthroughs don’t automatically break through; they need a voice, be well presented, and connect with the audience. Without these, even the most insightful finding risks staying a hidden gem—brilliant, but unseen.
Today, good science communication is not just a “nice-to-have” skill—it’s essential for building a successful career as a scientist. From publishing in high-impact journals and giving convincing talks to attracting collaborators and securing funding: being able to communicate well ensures that your work gets recognized.
In this talk, I will explore key aspects of how to communicate research in ways that are clear, compelling, and memorable—whether to your peers, collaborators from a different field, or the public. We will look at how to turn complex concepts into ideas people can understand, how to make your research resonate, and how to deliver your message so it sticks. By the end, you will have practical tools to help you communicate your research effectively.

Harnessing Competitive Interactions to Regulate Supramolecular Assembly
Abstract:
Understanding the interplay between supramolecular polymerization and phase separation is key to unraveling the formation of biomolecular assemblies such as protein fibers and membraneless organelles. I will present a minimal synthetic system—comprising a BTA-based monomer, surfactant, and water—that mimics biological condensates through a micelle-to-droplet-to-fiber transition. This pathway, governed by competitive interactions, is reversible under external stimuli like temperature and guest molecules. Our findings offer a framework for controlling supramolecular order and dynamics, with implications for synthetic biology and therapeutic design.

Title: Molecular sociology of self-organising genomes
Abstract:
Proteins organise the genome across multiple length and time scales. How proteins collectively bridge these scales to generate structure execute enzymatic reactions remains an open question. In this talk, I will discuss our work on dissecting biophysical mechanisms of genome self-organization, and how these principles are linked to transcription. To tackle these questions, we use interdisciplinary approaches that combine single molecule biophysics, reconstitution biology, and theory. I will describe how protein condensation acts as an organizing principle of genome organization, generating forces on DNA that then act as active enzymatic scaffolds.

Title: Bridging Scales in Molecular Dynamics Simulations with Machine Learning
Abstract:
Grasping the behavior of biomolecules across diverse length and time scales is a persistent challenge in molecular biophysics. While atomistic simulations provide detailed molecular insights, their high computational cost limits their applicability. Coarse-grained models, on the other hand, allow access to longer timescales and larger systems but often sacrifice resolution and accuracy. To connect these approaches meaningfully, it is essential to develop strategies that can bridge the scales and preserve key thermodynamic properties.
In this talk, I will showcase recent advances in leveraging machine learning for the analysis of free energy landscapes. I will demonstrate how tools such as dimensionality reduction and clustering can uncover key collective variables and metastable states from high-dimensional simulation data. Moreover, I will explore how these learned representations can facilitate the transfer of insights between different modeling resolutions, enabling seamless integration of coarse-grained and atomistic simulations. Applications to systems with complex multi-body interactions will illustrate the power of this multiscale, data-driven perspective.
