- GPCR kinase phosphorylation of distal C-tail sites specifies βarrestin1-mediated signaling by...
September 2022 "G protein-coupled receptor (GPCR) kinases (GRKs) and arrestins mediate GPCR desensitization The spatial pattern of GPCR phosphorylation is predicted to trigger these discrete GRK and arrestin-mediated We demonstrate by pharmacologic inhibition of GRK2/3-mediated phosphorylation of the chemokine receptor In conclusion, this study provides evidence that distal C-tail phosphorylation sites specify GRK-βarrestin-mediated
- GPCR kinases generate an APH1A phosphorylation barcode to regulate amyloid-β generation
August 2022 "Emerging evidence suggests that G protein-coupled receptor (GPCR) kinases (GRKs) are associated However, GRKs have not been directly implicated in regulation of the amyloid-β (Aβ) pathogenic cascade Here, we determine that GRKs phosphorylate a non-canonical substrate, anterior pharynx-defective 1A ( Significantly, we show that GRKs generate distinct phosphorylation barcodes in intracellular loop 2 (
- β-arrestin1 and 2 exhibit distinct phosphorylation-dependent conformations when coupling to the...
Employing GRK knockout cells and β-arrestins lacking the finger-loop-region, we show that the two isoforms specifically by proximal and distal C-terminal phosphorylation and in the absence of GPCR kinases (GRKs

- Ep 112 with Julia Gardner
She recently led a project that demonstrated the GPCR kinases (GRKs) can translocate to endosomes, and that the subcellular localization of the GRKs affects a GPCR's biased signaling profile.
- Ep 131 with Dr. Richard Premont
initial project to identify and clone taste receptors was unsuccessful, but led to the identification of GRK5 and continued focus on GRKs (particularly GRKs 4,5,6) and arrestins as GPCR regulators and as mediators regulation of G protein-coupled receptor signaling particularly by the G protein-coupled receptor kinase (GRK
