NMR and EPR reveal a compaction of the RNA-binding protein FUS upon droplet formation
Many RNA-binding proteins undergo liquid-liquid phase separation, which underlies the formation of membraneless organelles, such as stress granules and P-bodies. Studies of the molecular mechanism of phase separation in vitro are hampered by the coalescence and sedimentation of organelle-sized droplets interacting with glass surfaces. Here, we demonstrate that liquid droplets of fused in sarcoma (FUS)-a protein found in cytoplasmic aggregates of amyotrophic lateral sclerosis and frontotemporal...

[NMR paper] Optical control of protein pattern formation
Optical control of protein pattern formation
Patterns formed by protein reactions and diffusion are the foundation for many phenomena in biology. Yet, the experimental study of reaction-diffusion (R-D) systems has so far been dominated by chemical oscillators, for which many manipulation tools are available. Here, we developed a photoswitch for the Min system of Escherichia coli, a versatile biological in vitro R-D system consisting of the antagonistic proteins MinD and MinE. A MinE-derived peptide of 19 amino acids is covalently modified with a photoisomerizable crosslinker based on...

[NMR paper] Peptide-Directed Binding for the Discovery of Modulators of ?-Helix-Mediated Protein–Protein Interactions: Proof-of-Concept Studies with the Apoptosis Regulator Mcl-1
Peptide-Directed Binding for the Discovery of Modulators of ?-Helix-Mediated Protein–Protein Interactions: Proof-of-Concept Studies with the Apoptosis Regulator Mcl-1
Targeting PPIs with small molecules can be challenging owing to large, hydrophobic binding surfaces. Herein, we describe a strategy that exploits selective ?-helical PPIs, transferring these characteristics to small molecules. The proof of concept is demonstrated with the apoptosis regulator Mcl-1, commonly exploited by cancers to avoid cell death. Peptide-directed binding uses few synthetic transformations, requires the...

Abstract
Clustered regularly interspaced short palindromic repeats (CRISPR) form the basis of diverse adaptive immune systems directed primarily against invading genetic elements of archaea and bacteria. Cbp1 of the crenarchaeal...
