AI-driven structural analysis in biotechnology: a GS3 Science & Technology and Synthetic Biology case study.
Why in news
Researchers at the Innovative Genomics Institute (IGI) discovered the VIPR viral system using AI-assisted structural analysis to screen 2.3 million proteins.
Background
The VIPR system was identified by researchers Peter Yoon and Kenneth Loi using AI to screen 2.3 million protein structures. Published in 'Science' in September 2026, the system forms a triplex to silence genes and may explain ancient Class 1 CRISPR origins.
