Abstract

Increasingly, it is possible to design peptide and protein assemblies de novo from first principles or computationally. This approach provides new routes to functional synthetic polypeptides, including designs to target and bind proteins of interest. Much of this work has been developed in vitro. Therefore, a challenge is to deliver de novo polypeptides efficiently to sites of action within cells. Here we describe the design, characterisation, intracellular delivery, and subcellular localisation of a de novo synthetic peptide system. This system comprises a dual-function basic peptide, programmed both for cell penetration and target binding, and a complementary acidic peptide that can be fused to proteins of interest and introduced into cells using synthetic DNA. The designs are characterised in vitro using biophysical methods and X-ray crystallography. The utility of the system for delivery into mammalian cells and subcellular targeting is demonstrated by marking organelles and actively engaging functional protein complexes.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The Asn17-Asn17 hydrogen bond in CC-Di and the Asp@e-Arg@a hydrogen bonds/salt bridges in apCC-Di determine the formation of parallel and antiparallel dimers, respectively.

    “Of notable importance are the Asn17-Asn17 hydrogen bond in CC-Di, and the Asp@e-Arg@a hydrogen bonds/salt bridges in apCC-Di, which determine the formation of parallel and antiparallel dimers, respectively.33,89”
  • apCC-Di experimentally only accesses the antiparallel dimer state, also has a lower ΔGbind,total°/helix (−5.3 ± 0.5 kcal mol-1) compared to the other single-state coiled coils, but it has a lower melting point.

    “We note that apCC-Di, which experimentally only accesses the antiparallel dimer state, also has a lower ΔGbind,total◦/helix (−5.3 ± 0.5 kcal mol–1) compared to the other single-state coiled coils, but it has a lower melting point.89”

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.
