Abstract

Protein structure prediction and design can be regarded as two inverse processes governed by the same folding principle. Although progress remained stagnant over the past two decades, the recent application of deep neural networks to spatial constraint prediction and end-to-end model training has significantly improved the accuracy of protein structure prediction, largely solving the problem at the fold level for single-domain proteins. The field of protein design has also witnessed dramatic improvement, where noticeable examples have shown that information stored in neural-network models can be used to advance functional protein design. Thus, incorporation of deep learning techniques into different steps of protein folding and design approaches represents an exciting future direction and should continue to have a transformative impact on both fields.

  • Existing protein structure prediction methods fall far short of atomic or experimental accuracy, especially when no homologous structure is available, limiting their utility for many biological applications.

    “Despite recent progress10–14, existing methods fall far short of atomic accuracy, especially when no homologous structure is available.”

    From Highly accurate protein structure prediction with AlphaFold (2021) · cites this paper as [14]

    The Conclusion and Future Directions section says nearly one-third of AlphaFold2 single-domain models were below experimental accuracy, and the AlphaFold2 section identifies targets without templates as the hardest to model. But the paper does not characterize existing methods as uniformly falling far short: it reports that about two-thirds of AlphaFold2 models were comparable to low-to-medium-resolution experimental models and that it correctly folded the core regions of nearly all template-free targets. The cited passages have no page numbers in our copy. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
