maintaining the responsiveness of canonical G protein–coupled chemokine receptors that bind to the same ligand Chemokine scavenging mechanism involves internalization and recycling of the receptor with clearance of the ligand Zhao et al. 2019) together with confocal fluorescence microscopy. Hansell et al. 2011); and it may interfere with other chemokine receptors which share the ligands and function should be considered when evaluating the safety and therapeutic efficacy of blocking receptor-ligand

These include overexpression, tags, and fluorescent imaging. These probes shift brightness and fluorescence lifetime as pH changes. They learned how to fine-tune both brightness and fluorescence lifetime.

In this session, we work through: How allosteric ligands redistribute receptor species rather than displace ligands Why binding and function diverge as a consequence of state selection What displacement curves The ligand stabilizes a receptor species that binds agonist efficiently but does not engage downstream Binding reports ligand-compatible conformations Function reports signaling-competent conformations These The ligand does not “block” or “replace” another ligand; it biases the population of receptor states.

When AUR is oxidized by APEX2 in the presence of H 2 O 2 , it produces a fluorescent product that can This fluorescence serves as a readout for the activity of APEX2 and, by extension, the trafficking of

Watch Episode 171 What happens when your protein has no known ligands, no structure, and very little The Problem: Hundreds of Receptors, Almost No Ligands Alessandro’s work focuses on olfactory GPCRs—nearly Most have only one known ligand, if any. That meant simulations, ligand screening, and experimental design could move forward with confidence. More accurate hypotheses, faster ligand discovery, and new strategies to tackle one of biology’s most

Allosteric Modulators as Novel Intracellular Molecular Glues Classic models explain biased signaling through ligands such as SBI-553 at NTSR1 and PCO371 at PTH1R , already characterized, provide concrete cases where ligands This AMA will discuss how these formats diverge, particularly for allosteric ligands, where efficacy Allosteric modulators can alter signaling efficacy without changing ligand affinity, uncoupling binding Read analysis ➤ Computational descriptions of ligand bias remain central to linking structural motion

Can we leverage structural and computational insights not just to explain receptor–ligand interactions after the fact, but to forecast outcomes and design ligands with new properties? To tackle these, the lab employs molecular docking, molecular dynamics simulations, and ligand-based When existing compounds are exhausted, bespoke ligands are designed and synthesized in-house. Common questions in the group include: Can we forecast ligand efficacy or selectivity?

In this session, you’ll gain: ✅ A deeper understanding of how every ligand alters receptor conformation—and Ligands don’t just “bind”—they change  the receptor. Ligands may take hours to equilibrate , even when they look potent on paper. What If the Same Site Behaves Differently Depending on the Ligand? In this lecture, Kenakin lays out why no ligand binds without altering receptor conformation , and how
