Abstract

Bridging integrator 1 (bin1) gene is a genetic determinant of Alzheimer's disease (AD) and has been reported to modulate Alzheimer's pathogenesis through pathway(s) involving Tau. The functional impact of Tau/BIN 1 interaction as well as the molecular details of this interaction are still not fully resolved. As a consequence, how BIN 1 through its interaction with Tau affects AD risk is also still not determined. To progress in this understanding, interaction of Tau with two BIN 1 isoforms was investigated using Nuclear Magnetic Resonance spectroscopy. 1 H, 15 N spectra showed that the C‐terminal SH 3 domain of BIN 1 isoform 1 (BIN 1Iso1) is not mobile in solution but locked with the core of the protein. In contrast, the SH 3 domain of BIN 1 isoform 9 (BIN 1Iso9) behaves as an independent mobile domain. This reveals an equilibrium between close and open conformations for the SH 3 domain. Interestingly, a 334–376 peptide from the clathrin and AP‐2‐binding domain (CLAP) domain of BIN 1Iso1, which contains a SH 3‐binding site, is able to compete with BIN 1‐SH 3 intramolecular interaction. For both BIN 1 isoforms, the SH 3 domain can interact with Tau(210–240) sequence. Tau(210–240) peptide can indeed displace the intramolecular interaction of the BIN 1‐SH 3 of BIN 1Iso1 and form a complex with the released domain. The measured Kd were in agreement with a stronger affinity of Tau peptide. Both CLAP and Tau peptides occupied the same surface on the BIN 1‐SH 3 domain, showing that their interaction is mutually exclusive. These results emphasize an additional level of complexity in the regulation of the interaction between BIN 1 and Tau dependent of the BIN 1 isoforms.

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.
