Abstract

ABC (ATP binding cassette) transporters, ubiquitous in all kingdoms of life, carry out essential substrate transport reactions across cell membranes. Their transmembrane domains bind and translocate substrates and are connected to a pair of nucleotide binding domains, which bind and hydrolyze ATP to energize import or export of substrates. Over four decades of investigations into ABC transporters have revealed numerous details from atomic-level structural insights to their functional and physiological roles. Despite all these advances, a comprehensive understanding of the mechanistic principles of ABC transporter function remains elusive. The human multidrug resistance transporter ABCB1, also referred to as P-glycoprotein (P-gp), is one of the most intensively studied ABC exporters. Using ABCB1 as the reference point, we aim to compare the dominating mechanistic models of substrate transport and ATP hydrolysis for ABC exporters and to highlight the experimental and computational evidence in their support. In particular, we point out in silico studies that enhance and complement available biochemical data.

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

  • Gene 397 of L. johnsonii encoded an ABC-F family ATP-binding cassette domain-containing protein, crucial for transmembrane transport.

    From Gut microbiota drives structural variation of exogenous probiotics to enhance colonization (2025) · cites this paper as [30]

    The Introduction to ABC transporter function and architecture (page unavailable) says ABC-F proteins consist only of nucleotide-binding domains, lack transmembrane domains, and participate in DNA repair and translation—not transmembrane transport. The paper does not identify gene 397 of L. johnsonii; that detail is unsupported rather than contradicted. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

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.
