Abstract

INTRODUCTION: The application of high-throughput genomic approaches has revealed 24 novel risk loci for Alzheimer's disease (AD). We recently reported that the bridging integrator 1 (BIN1) risk gene is linked to Tau pathology. RESULTS: We used glutathione S-transferase pull-down assays and nuclear magnetic resonance (NMR) experiments to demonstrate that BIN1 and Tau proteins interact directly and then map the interaction between BIN1's SH3 domain and Tau's proline-rich domain (PRD) . Our NMR data showed that Tau phosphorylation at Thr231 weakens the SH3-PRD interaction. Using primary neurons, we found that BIN1-Tau complexes partly co-localize with the actin cytoskeleton; however, these complexes were not observed with Thr231-phosphorylated Tau species. CONCLUSION: Our results show that (i) BIN1 and Tau bind through an SH3-PRD interaction and (ii) the interaction is downregulated by phosphorylation of Tau Thr231 (and potentially other residues). Our study sheds new light on regulation of the BIN1/Tau interaction and opens up new avenues for exploring its complex's role in the pathogenesis of AD.

  • The BIN1 SH3 domain can interact with proteins including c-Abl, N-WASP, actin, myosin, and Tau, suggesting involvement of the cytoskeleton in BIN1 function.

    “In addition to proteins involved in endocytosis, the BIN1 SH3 domain can interact with a number of other proteins including the tyrosine kinase c-Abl, the actin nucleation-promoting factor N-WASP, actin, myosin, and Tau, suggesting the involvement of the cytoskeleton in BIN1 function [18–21].”

    From Predominant expression of Alzheimer’s disease-associated BIN1 in mature oligodendrocytes and localization to white matter tracts (2016) · cites this paper as [21]

    The Results and Discussion show that BIN1’s SH3 domain interacts with Tau and that BIN1–Tau complexes partly co-localize with the actin cytoskeleton. Our copy does not establish SH3-domain interactions with c-Abl, N-WASP, actin, or myosin; its discussion of BIN1 and actin concerns BIN1 more broadly. (LLM, conf=0.87)

  • Human BIN1 directly binds Tau, and this interaction in neurons depends on the level of BIN1 expression and the phosphorylation statuses of both BIN1 and Tau.

    “human BIN1 directly binds Tau and this interaction in neurons depends on the level of BIN1 expression, as well as the phosphorylation statuses of both BIN1 and Tau [85, 89, 110, 124].”

    From The new genetic landscape of Alzheimer’s disease: from amyloid cascade to genetically driven synaptic failure hypothesis? (2019) · cites this paper as [124]

    The Discussion reports direct binding between BIN1’s SH3 domain and Tau and says Tau phosphorylation weakens their interaction both in vitro and in primary neurons. The Introduction and Discussion mention elevated BIN1 expression in AD brains, but do not establish that BIN1 expression level regulates the interaction in neurons. The cited passages also do not show that BIN1’s own phosphorylation status regulates it. Page numbers were not available in our copy. (LLM, conf=0.88)

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.
