A Tri-Stimuli-Responsive Shape-Memory Material Using Host-Guest Interactions as Molecular Switches

, 2016
A thermo-, photo-and chemoresponsive shape-memory material is successfully prepared by introducing alpha-cyclodextrin (alpha CD) and azobenzene (Azo) into a poly(acrylate acid)/alginate (PAA/Alg) network. The tri-stimuli-responsive formation/dissociation

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

FEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Nucleic acid molecular switches

Trends in Biotechnology, 1999
Natural and artificial ribozymes can catalyse a diverse range of chemical reactions. Through recent efforts in enzyme engineering, it has become possible to tailor the activity of ribozymes to respond allosterically to specific effector compounds. These allosteric ribozymes function as effector-dependent molecular switches that could find application ...

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Reversible end-to-end assembly of selectively functionalized gold nanorods by light-responsive arylazopyrazole–cyclodextrin interaction

Beilstein Journal of Organic Chemistry, 2019
We propose a two-step ligand exchange for the selective end-functionalization of gold nanorods (AuNR) by thiolated cyclodextrin (CD) host molecules. As a result of the complete removal of the precursor capping agent cetyltrimethylammonium bromide (CTAB ...

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.
