Endosomal signaling of delta opioid receptors is an endogenous mechanism and therapeutic target for relief from inflammatory pain (2020)
Journal Article

Low intrinsic efficacy for G protein activation can explain the improved side-effect profile of new opioid agonists (2020)
Journal Article

Biased agonism at G protein–coupled receptors describes the phenomenon whereby some drugs can activate some downstream signaling activities to the relative exclusion of others. Descriptions of biased agonism focusing on the differential engagement of...

A tetrapeptide class of biased analgesics from an Australian fungus targets the µ-opioid receptor (2019)
Journal Article

An Australian estuarine isolate ofPenicilliumsp. MST-MF667 yielded3 tetrapeptides named the bilaids with an unusual alternating LDLDchirality. Given their resemblance to known short peptide opioidagonists, we elucidated that they were weak (Kilow mic...

Preassembled GPCR signaling complexes mediate distinct cellular responses to ultralow ligand concentrations (2018)
Journal Article

G protein–coupled receptors (GPCRs) are the largest class of cell surface signaling proteins, participate in nearly all physiological processes, and are the targets of 30% of marketed drugs. Typically, nanomolar to micromolar concentrations of ligand... Read More about Preassembled GPCR signaling complexes mediate distinct cellular responses to ultralow ligand concentrations.
