Understanding Allosteric Modulation of G-Protein Coupled Receptors [PDF]

, 2016
G protein-coupled receptors (GPCRs) which are seven-transmembrane allosteric machine constitutes largest and diverse family of membrane proteins. GPCR participate in activating a diverse range of signaling pathways, in response to ligand perturbation ...

Allosteric Lever: Toward a Principle of Specific Allosteric Response

Physical Review X
Allostery, the phenomenon by which the perturbation of a molecule at one site alters its behavior at a remote functional site, enables control over biomolecular function.

Allosteric modulation by the fatty acid site in the glycosylated SARS-CoV-2 spike

eLife
The spike protein is essential to the SARS-CoV-2 virus life cycle, facilitating virus entry and mediating viral-host membrane fusion. The spike contains a fatty acid (FA) binding site between every two neighbouring receptor-binding domains.

Entropy‐Driven Physical Amplification in Multivalent Biosensing

Advanced Science, EarlyView.
Detecting scarce molecules usually demands enzymatic amplification such as PCR. A statistical‐mechanical theory now reveals a purely physical alternative: distributing a fixed binding strength over more linker arms exponentially lowers the concentration at which multivalent sensors switch on.

The impact of ERAP1 inhibition on metabolite homeostasis of melanoma cells

Scientific Reports
Manipulation of the activity of Endoplasmic Reticulum AminoPeptidase 1 (ERAP1) has emerged as a powerful tool for the modulation of the cellular antigenicity and concomitant adaptive immune responses, with potential applications in cancer immunotherapy ...

Switching Spike Plasticity Shapes ACE2 Engagement Across SARS‐CoV‐2 Variants

Advanced Science, EarlyView.
Conformational plasticity governs SARS‐CoV‐2 spike function and ACE2 recognition. Using high‐speed AFM and single‐molecule force spectroscopy, we analyzed the ancestral spike and nine variants, revealing progressive rigidification from Delta, variable plasticity in Omicron sublineages, and JN.1 compaction.

Supramolecular Degraders: An Emerging Paradigm in Targeted Protein Degradation

Advanced Science, EarlyView.
Dynamic supramolecular assembly reshapes targeted protein degradation by coordinating modular degrader construction, delivery, functional integration, and intracellular assembly or activation across proteasomal, endosomal–lysosomal, and autophagy–lysosomal pathways.

Targeting β2‐Adrenergic Receptor Stability With Lycorine Reveals a Host‐Directed Pathway for Antiviral Defense Against Poxviruses

Advanced Science, EarlyView.
Chronic stress drives autophagy‐mediated β2‐AR degradation, impairing antiviral immunity and promoting poxvirus lethality. Lycorine directly stabilizes β2‐AR to restore host defense, suppress excessive inflammation and improve survival. ABSTRACT Psychological stress is a pervasive yet poorly understood modulator of infectious disease outcomes. Here, we

Identification and qualification of a new family of peptide endocannabinoids (Pepcans) showing negative allosteric modulation at CB1 receptors

, 2012
The alpha-hemoglobin-derived dodecapeptide RVD-hemopressin (RVDPVNFKLLSH) has been proposed to be an endogenous agonist for the cannabinoid receptor type-1 (CB1).

A Synthetic Platform for Antibody Junctional Diversification Beyond Natural Constraints

Advanced Science, EarlyView.
ARESEC is a synthetic platform that reconstructs functional V(D)J recombination in HEK293T cells. By introducing RSS elements and co‐expressing RAG1/2 and TdT across all three antibody CDRs, it enables programmable junctional diversification and direct generation of high‐affinity variants targeting PD‐1/PD‐L1, overcoming the evolutionary constraints of
