Structure of the intracellular domain of the amyloid precursor protein in complex with Fe65-PTB2.
EMBO Rep. 9, 1134-1140 (2008)
Cleavage of the amyloid precursor protein (APP) is a crucial event in Alzheimer disease pathogenesis that creates the amyloid-beta peptide (A beta) and liberates the carboxy-terminal APP intracellular domain (AICD) into the cytosol. The interaction of the APP C terminus with the adaptor protein Fe65 mediates APP trafficking and signalling, and is thought to regulate APP processing and A beta generation. We determined the crystal structure of the AICD in complex with the C-terminal phospho-tyrosine-binding (PTB) domain of Fe65. The unique interface involves the NPxY PTB-binding motif and two alpha helices. The amino-terminal helix of the AICD is capped by threonine T-668, an Alzheimer disease-relevant phosphorylation site involved in Fe65-binding regulation. The structure together with mutational studies, isothermal titration calorimetry and nuclear magnetic resonance experiments sets the stage for unterstanding T-668 phosphorylation-dependent complex regulation at a molecular level. A molecular switch model is proposed.
