Lipid composition controls the huntingtin exon 1 membrane‐association and differentially modulates its flanking regions' dynamics

Protein Science, Volume 35, Issue 6, June 2026.
Abstract The pathological expansion of the polyglutamine (polyQ) repeat within the first exon of huntingtin (Httex1) protein is a defining hallmark of Huntington's disease (HD). Multiple evidence supports that the membrane recruitment of Httex1 is critical for its self‐assembly and related toxicity in HD.

Comparative Study of Two Spectral Methods for Estimating the Excited State Dipole Moment of Non-Fluorescent Molecules

Molecules
The electronic absorption spectral characteristics of cycloimmonium ylids with a zwitterionic structure have been analyzed in forty-three solvents with different hydrogen bonding abilities. The two ylids lack fluorescence emission but are very dynamic in

Physics-informed machine learning to predict solvatochromic parameters of designer solvents with case studies in CO2 and lignin dissolution

Green Chemical Engineering
The polarity of solvents plays a critical role in various research applications, particularly in their solubilities. Polarity is conveniently characterized by the Kamlet-Taft parameters that is, the hydrogen bonding acidity (α), the basicity (β), and the
