Watermarked proteins kept their function in lab tests. ## Method The sequence watermark is a tiny bias in amino acid choices; a second method writes the signature into the atomic coordinates of the predicted 3D structure. Detection is 100% for sequences and above 99.8% for structures at a 0.1% false positive rate. ## Lab results The team designed binders for VEGF-A, PD-L1 and the SARS-CoV-2 binding domain. Watermarked designs matched unmarked ones on hit rate, affinity and sequence diversity. ## What it is for The target is DNA synthesis screening: a watermark would tell providers automatically that an order came from a model with safeguards. Resistance to deliberate tampering is still unsolved, and the tools are being open-sourced. ## More articles [News · Funding ### ElevenLabs reaches $22 billion in employee share sale 30 Sep 2026 · 1 min](https://www.qanatone.com/en/haber/elevenlabs-22-milyar-dolar-degerleme/)[News · Policy ### FTC opens probe into OpenAI and Anthropic over rogue agents 30 Sep 2026 · 1 min](https://www.qanatone.com/en/haber/ftc-yapay-zeka-laboratuvarlari-sorusturmasi/)[News · Models ### Google unveils Gemini 4 Argon after months of delay 30 Sep 2026 · 1 min](https://www.qanatone.com/en/haber/google-gemini-4-argon/)[News · Infrastructure ### Meta cut $3.9 billion in tax by calling data centers experiments 30 Sep 2026 · 1 min](https://www.qanatone.com/en/haber/meta-veri-merkezi-vergi-kredisi/)[News · Funding ### OpenAI seeks $30 billion round instead of an IPO 30 Sep 2026 · 1 min](https://www.qanatone.com/en/haber/openai-30-milyar-dolar-fon-turu/)[News · Policy ### US agencies told to say super intelligence instead of AI 30 Sep 2026 · 1 min](https://www.qanatone.com/en/haber/super-zeka-kararnamesi-federal-kurumlar/)[News · Search ### US launches America.gov, an AI portal for federal services 29 Sep 2026 · 1 min](https://www.qanatone.com/en/haber/america-gov-yapay-zeka-portali/)[News · Funding ### Anthropic's IPO draft: compute spend tripled 29 Sep 2026 · 1 min](https://www.qanatone.com/en/haber/anthropic-halka-arz-taslagi/)
