What it is

ProteinMPNN solves the inverse-folding problem: given a target backbone, it designs amino-acid sequences that reliably fold to it, dramatically outperforming physics-based design. LigandMPNN adds awareness of small molecules, metals and nucleic acids for functional-site design.

Evidence trail

BioAtlas keeps the path from source to decision visible. A connection records provenance; it does not imply that evidence is sufficient for every context.

These records describe active research directions, not guaranteed capabilities of this model. Evidence stages and unresolved questions are preserved separately.

Generative biomolecular design

Prospective de novo binder generation

Google DeepMind · 2024-09-05
Prospective demonstration

Can AI generate high-affinity protein binders for diverse targets with fewer rounds of experimental optimization?

Evidence boundary and unresolved questions

Performance varies by target; the system did not succeed on every attempted target and is not publicly released for unrestricted reproduction.

  • Which target properties predict designability?
  • How transferable are success rates to membrane and flexible targets?
  • Can developability, immunogenicity and function be optimized jointly?

Scientific lineage

Explore all foundations

These are transparent concept matches—not claims that one scientist alone caused this model. Each connection is based on the model’s recorded domain, scientific principles, technical terms or an explicit lineage link.

Structural biology

Anfinsen’s dogma—the thermodynamic hypothesis

Christian B. Anfinsen

Protein structure prediction, inverse folding and generative protein design all assume that sequence strongly constrains structure and function.

Levinthal’s paradox and efficient folding pathways

Cyrus Levinthal

Modern folding algorithms, energy landscapes, learned priors and diffusion models solve a constrained search problem rather than brute-force conformational enumeration.
