Development of tools and methods for protein identification: From single molecules to in vivo applications

As the fundamental machinery orchestrating cellular functions, proteins influence the state of every cell profoundly. As cells exhibit significant variations from one to another, analyzing the proteome on a single-cell level is imperative to unravel their ...

A minimalistic cyclic ice-binding peptide from phage display

Harm-Anton Klok, Luciano Andres Abriata, Matthew Gibson, Xudong Kong, Corey Alfred Stevens

Developing molecules that emulate the properties of naturally occurring ice-binding proteins (IBPs) is a daunting challenge. Rather than relying on the (limited) existing structure–property relationships that have been established for IBPs, here we report ...

The functional proteome landscape of Escherichia coli

Camille Véronique Bernadette Goemans

Recent developments in high-throughput reverse genetics1,2 have revolutionized our ability to map gene function and interactions3,4,5,6. The power of these approaches depends on their ability to identify functionally associated genes, which elicit similar ...

Protein Engineering Tools to Explore the Function of Protein Post-Translational Modifications for Chromatin and Microtubule Cytoskeletal Biology

Ninad Dilip Agashe

Protein post-translational modifications (PTMs) play a crucial role in expanding the protein diversity and are one of the major mechanisms through which cells respond to ever changing environmental cues. The function of two of the most important cellular c ...

A bi-terminal protein ligation strategy to probe chromatin structure during DNA damage

Beat Fierz, Sinan Kilic, Iuliia Boichenko, Carolin Christine Lechner

The cellular response to DNA damage results in a signaling cascade that primes chromatin for repair. Combinatorial post-translational modifications (PTMs) play a key role in this process by altering the physical properties of chromatin and recruiting downs ...

Evolution of an intricate J-protein network driving protein disaggregation in eukaryotes

Paolo De Los Rios, Alessandro Barducci, Duccio Malinverni

Hsp70 participates in a broad spectrum of protein folding processes extending from nascent chain folding to protein disaggregation. This versatility in function is achieved through a diverse family of J-protein cochaperones that select substrates for Hsp70 ...

Heterochromatin protein 1 recruitment and chromatin conformational dynamics at the single-molecule level

Sinan Kilic

Chromatin is the template on which DNA-associated transactions take place in eukaryotic organisms. Nucleosomes consisting of the four histones H2A, H2B, H3 and H4 each organize ~150bp of DNA and constitute a first layer of chromatin. The three-dimensional ...

Mutant Exon1 Huntingtin Aggregation is Regulated by T3 Phosphorylation-Induced Structural Changes and Crosstalk between T3 Phosphorylation and Acetylation at K6

Giovanni Dietler, Hilal Lashuel, Anass Chiki, Francesco Simone Ruggeri, Urszula Beata Cendrowska, Annalisa Ansaloni, Ritwik Burai, Sean Michael Deguire, Sophie Vieweg

Herein, we used protein semisynthesis to investigate, for the first time, the effect of lysine acetylation and phosphorylation, as well as the crosstalk between these modifications on the structure and aggregation of mutant huntingtin exon1 (Httex1). Our r ...

Elucidating the Role of Site-Specific Nitration of alpha-Synuclein in the Pathogenesis of Parkinson's Disease via Protein Semisynthesis and Mutagenesis

Hilal Lashuel, Anass Chiki, Nadine Aït Bouziad, Ritwik Burai

Parkinsons disease (PD) is characterized by the loss of dopaminergic neurons in the substantia nigra and the presence of intraneuronal inclusions consisting of aggregated and post-translationally modified a-synuclein (a-syn). Despite advances in the chemic ...

A chemostat array enables the spatio-temporal analysis of the yeast proteome

Michaël Unser, Felix Naef, Sebastian Maerkl, Nicolas Dénervaud, Ricard Delgado Gonzalo, Johannes Becker, Arun Stephen Rajkumar

Observing cellular responses to perturbations is central to generating and testing hypotheses in biology. We developed a massively parallel microchemostat array capable of growing and observing 1,152 yeast-GFP strains on the single-cell level with 20 min t ...
