Google DeepMind watermarks AI-designed proteins, and the first binders still bind

Google DeepMind has applied its SynthID watermark to biology and says its first watermarked protein binders still bind. In wet-lab testing against three target proteins — VEGF-A, the SARS-CoV-2 spike protein RBD, and PD-L1 — the company says the watermarked designs "matched the hit rate, binding affinity, and natural sequence diversity of unwatermarked versions."
