Activity‐restoring mutations in the histamine H3 receptor increase constitutive activity and reduce structural stability

open access: yesProtein Science, Volume 35, Issue 1, January 2026.
Abstract The histamine H3 receptor (H3R) is a class A G protein‐coupled receptor (GPCR) that regulates neurotransmitter release in the central nervous system. Although structures of H3R in both inactive and active states have been elucidated, the functional roles of specific residues remain unclear.

Adsorption of Nucleic Acid Bases, Ribose, and Phosphate by Some Clay Minerals

open access: yesLife, 2015
Besides having a large capacity for taking up organic molecules, clay minerals can catalyze a variety of organic reactions. Derived from rock weathering, clay minerals would have been abundant in the early Earth. As such, they might be expected to play a

Synthesis, Cyclopolymerization and Cyclo-Copolymerization of 9-(2-Diallylaminoethyl)adenine and Its Hydrochloride Salt

open access: yesMolecules, 2012
We report herein the synthesis and characterization of 9-(2-diallylaminoethyl) adenine. We evaluated two different synthetic routes starting with adenine where the optimal route was achieved through coupling of 9-(2-chloroethyl)adenine with diallylamine.

Structure of non-viral vectors based on cholesteric liquid-crystal polymers by SAXS [PDF]

open access: yes, 2016
Cationic polymers, at physiological pH, are used to condense anionic nucleic acids, as healing agent, into nano-sized particle-like complexes called “polyplexes”, through self-assembly driven by electrostatic interactions. By compressing DNA molecules to

An Estimate of the Vibrational Frequencies of Spherical Virus Particles

open access: yes, 2003
The possible normal modes of vibration of a nearly spherical virus particle are discussed. Two simple models for the particle are treated, a liquid drop model and an elastic sphere model.

Mesoscopic irreversible thermodynamics of aging kinetics of alpha polypeptides [DNA] under various constraints: Special reference to the simple spring mechanics

open access: yesAIP Advances
The mesoscopic irreversible thermodynamic treatment of α-polypeptides and the helical polynucleotides (DNA) furnishes two sets of analytical expressions, which allow us not only to analyze the reversible force–extension experiments performed by atomic ...

Lipids contribute to epigenetic control via chromatin structure and functions

open access: yesScienceOpen Research, 2015
Isolated cases of experimental evidence over the last few decades have shown that, where specifically tested, both prokaryotes and eukaryotes have specific lipid molecules bound to nucleoproteins of the genome.
