BWhat changed
ESM3 generated protein candidates conditioned on sequence, structure and function. Human laboratory testing identified a bright fluorescent protein with substantial sequence differences from known fluorescent proteins.
Scientific scope
ESM3 generated protein candidates conditioned on sequence, structure and function. Human laboratory testing identified a bright fluorescent protein with substantial sequence differences from known fluorescent proteins. Scope limitation: The 2025 paper follows a 2024 preprint. The evolutionary-timescale analogy in its title is an estimate, not a literal simulation or experimentally observed evolutionary history. Generation, human selection and wet-lab validation are separate contributions; this does not establish general success across protein functions.
Evidence
The retained primary-source abstract, bibliographic record and stated review scope support this provisional assessment. No independent experimental replication by WRS is claimed.
