Abstract

Significance: Proximity-dependent biotinylation (BioID) is a readily accessible method for identifying protein associations that occur in living cells. Fusion of a promiscuous biotin ligase to a bait protein for expression in live cells enables covalent biotin labeling, and thus identification, of proteins proximate to the bait. Here we used BioID to probe the organization of the nuclear pore complex, a large structure that regulates molecular transport between the nucleus and cytoplasm. These studies enhance our understanding of major subcomplexes within the nuclear pore complex and demonstrate the utility of BioID for studying the organization of large protein assemblies. Additionally, we have measured the labeling radius of BioID, thus enabling the rational application of this method and more meaningful data interpretation.

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?

  • By fusing BirA* to a bait protein with a synaptic localization signal or nuclear pore signal, BirA* expression was specifically guided to the synapse or nuclear pore complex to achieve biotinylation of the respective proteomes.

    “By fusing BirA* to a bait protein with a synaptic localization signal or nuclear pore signal, BirA* expression was specifically guided to the synapse or nuclear pore complex to achieve biotinylation of the respective proteomes [167, 168].”

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.
