The structure of an amyloid precursor protein/talin complex indicates a mechanical basis of Alzheimer's disease.

Misprocessing of amyloid precursor protein (APP) is one of the major causes of Alzheimer's disease. APP comprises a large extracellular region, a single transmembrane helix and a short cytoplasmic tail containing an NPxY motif (normally referred to as the YENPTY motif). Talins are synaptic scaffold proteins that connect the cytoskeletal machinery to the plasma membrane via binding NPxY motifs in the cytoplasmic tail of integrins.
