Protein Semi-Synthesis in Living Cells
Abstract
Incorporation of chemical probes into proteins is a powerful way to elucidate biological processes and to engineer novel function. Here we describe an approach that allows ligation of synthetic molecules to target proteins in an intracellular environment. A cellular protein is genetically tagged with one-half of a split intein. The complementary half is linked in vitro to the synthetic probe, and this fusion is delivered into cells using a transduction peptide. Association of the intein halves in the cytosol triggers protein trans-splicing, resulting in the ligation of the probe to the target protein through a peptide bond. This process is specific and applicable to cytosolic and integral membrane proteins. The technology should allow cellular proteins to be elaborated with a variety of abiotic probes.

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.
