AI-designed miniproteins switch key cell receptors on and off

Phys · · 630 words · By University

Researchers from the UW Medicine Institute for Protein Design and Skape Bio have developed AI-designed miniproteins capable of activating or blocking G protein-coupled receptors (GPCRs). The study, published in Nature, also introduces a new screening system to test these proteins within living human cells to accelerate drug discovery.
