Effect of Phosphorylation Barcodes on Arrestin Binding to a Chemokine Receptor
Dr. Qiuyan Chen
Assistant Professor of Biochemistry & Molecular Biology
Indiana University School of Medicine

Cells often fine-tune their responses to signals through chemical tags called phosphorylation 'barcodes' placed on receptors at the cell surface. Different G-protein coupled receptor (GPCR) kinases (GRKs) add these barcodes at different sites, but how these patterns influence arrestins — key proteins that control receptor signaling and trafficking — has been unclear.

AI Reasoning in Theoretical Physics with the TPBench Project
Assistant Professor Moritz Münchmeyer
UW-Madison Department of Physics

Large-language models are becoming powerful enough to assist physicists with mathematical reasoning at the research level. In this talk, I will first present our dataset TPBench (tpbench.org), which was constructed to benchmark and improve AI models specifically for theoretical physics.
