Phosphorylation of LRP1 regulates the interaction with Fe65

Neuronal Fe65 is a central adapter for the intracellular protein network of Alzheimer’s diseaserelated amyloid precursor protein (APP). It contains a unique tandem array of phosphotyrosine-binding (PTB) domains that recognize NPXY internalization motifs present in the intracellulardomains of APP (AI...

Zusammenfassung:Neuronal Fe65 is a central adapter for the intracellular protein network of Alzheimer’s diseaserelated amyloid precursor protein (APP). It contains a unique tandem array of phosphotyrosine-binding (PTB) domains that recognize NPXY internalization motifs present in the intracellulardomains of APP (AICD) and the low-density lipoprotein receptor-related protein LRP1 (LICD). Theternary APP/Fe65/LRP1 complex is an important mediator of APP processing and affectsb-amyloidpeptide production. Here we dissect by biochemical and biophysical methods the direct interactionswithin the ternary complex and reveal a phosphorylation-dependent insulin receptor substrate(IRS-) like interaction of the distal NPVY4507motif of LICD with Fe65-PTB1.
