Innovative Approach Reveals How Receptors Control G Protein State Equilibria

ABSTRACT G protein‐coupled receptors (GPCRs) constitute the largest family of drug targets, acting through heterotrimeric G proteins. Agonist bound GPCRs promote GDP release from G proteins allowing their activation upon GTP binding. Here, we analyze this process with innovative tools that detect the main states of nat...

Distinct atypical chemokine receptor 1 determinants underlie bacterial toxins recognition and pore formation

Atypical chemokine receptor 1 (ACKR1) is one of the most promiscuous receptors in the human chemokine system, engaging structurally diverse chemokines through a conformationally flexible N-terminal tail. This same interface is exploited by pathogens, including Plasmodium vivax and Staphylococcus aureus (SA), via a comp...

Real-time analysis of pore formation by bi-component staphylococcal leukotoxins using the two-electrode voltage-clamp technique

A simple and highly sensitive method allowing cell surface expression of a large diversity of target receptors and recording in real-time, currents generated by neo-formed pores is developed, able to elucidate the kinetics of pore formation, the limiting role of receptors in this process, and propose a complementary mo...
