A minimalistic cyclic ice-binding peptide from phage display

Harm-Anton Klok, Luciano Andres Abriata, 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 ...

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, Francesco Simone Ruggeri, Anass Chiki, Sean Michael Deguire, Urszula Beata Cendrowska, Ritwik Burai, Annalisa Ansaloni, 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 ...
