Allosteric GPCR Pharmacology

Allosteric GPCR Pharmacology Poster

G protein-coupled receptors (GPCRs) are intrinsically allosteric proteins. This poster highlights some of the key insights into allosteric mechanisms of GPCR biology, highlighting key facets of GPCR allostery and therapeutic applications of allosteric modulators.

GPCR Efficacy and Biased Agonism

GPCR Efficacy and Biased Agonism Poster

GPCRs can interact with multiple distinct transducers or regulatory proteins and these can be preferentially engaged in an agonist-specific manner giving rise to biased agonism. This poster discusses cutting edge GPCR signaling pharmacology and highlights therapeutic applications of biased agonism.
