Abstract

We analyzed the mechanism of axonal transport of the amyloid precursor protein (APP), which plays a major role in the development of Alzheimer's disease. Coimmunoprecipitation, sucrose gradient, and direct in vitro binding demonstrated that APP forms a complex with the microtubule motor, conventional kinesin (kinesin-I), by binding directly to the TPR domain of the kinesin light chain (KLC) subunit. The estimated apparent Kd for binding is 15-20 nM, with a binding stoichiometry of two APP per KLC. In addition, association of APP with microtubules and axonal transport of APP is greatly decreased in a gene-targeted mouse mutant of the neuronally enriched KLC1 gene. We propose that one of the normal functions of APP may be as a membrane cargo receptor for kinesin-I and that KLC is important for kinesin-I-driven transport of APP into axons.

  • Characterization of the Kif5B antibodies showed that these antibodies recognize primarily Kif5B (based on in vitro assays with Kif5A and Kif5C) and turned out to be exceptionally clean despite being crude sera.

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.
