Molecular Details of RNA Interactions With FUS Condensates Altering Assembly, Dynamics, and Aggregation

Angewandte Chemie, EarlyView.
Using NMR and molecular simulations, we map how RNA engages FUS LC‐RGG1 within condensates through electrostatic, π‐stacking, and polar contacts. These multivalent RNA contacts help stabilize RNA within FUS condensates while also reshaping condensate composition and dynamics.

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics

Angewandte Chemie, EarlyView.
Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...

Site‐Specific Protein Bioconjugation Through Cellular Incorporation of Noncanonical Amino Acids

Angewandte Chemie, EarlyView.
Genetic code expansion (GCE) enables site‐specific installation of noncanonical amino acids containing bioorthogonal conjugation handles, allowing precise, homogeneous protein modification. This review examines the principles of orthogonal translation, surveys the chemistries available for chemoselective labeling, and highlights emerging multi‐site ...

Extending Small‐Molecule Aptamer Discovery Principles to Protein Targets: Selection and Characterization of Green Fluorescent Protein Aptamers

Angewandte Chemie, EarlyView.
Protein‐binding aptamers remain poorly understood compared to their small‐molecule counterparts. Using green fluorescent protein (GFP) variants as a tractable model system, we show how subtle changes in protein surface composition and divalent metal ions reshape aptamer selection, specificity, and binding.

Ligand‐Directed Molecular Beacons as Turn‐On Fluorescent Probes for Sensing Cell‐Surface Receptor‐Ligand Interactions

Angewandte Chemie, EarlyView.
Multivalent, ligand‐directed molecular beacons enable fluorescence turn‐on detection of cell‐surface receptors in living cells. The probes strongly engage closely spaced membrane receptors and exhibit conformation‐dependent fluorescence enhancement at the cell surface, enabling wash‐free receptor imaging, inhibitor screening, and functional evaluation ...

dsRADAR: Imaging and Detecting Cellular dsRNA by Repurposing RNA‐Binding Proteins

Angewandte Chemie, EarlyView.
Double‐stranded RNA (dsRNA) plays an important role in the innate immune system, but can be misregulated in disease, leading to inflammation. Despite the importance of this motif, methods for detecting dsRNA remain limited. This work shows that ADAR3 can be repurposed to provide improved detection of dsRNA, which is demonstrated in the context of viral
