The amyloid precursor protein and its network of interacting proteins: physiological and pathological implications
چکیده انگلیسی
The amyloid precursor protein (APP) is an ubiquitous receptor-like molecule involved in the pathogenesis of Alzheimer's disease that generates β-amyloid peptides and causes plaque formation. APP and some of its C-terminal proteolytic fragments (CTFs) have also been shown to be in the center of a complex protein-protein network, where selective phosphorylation of APP C-terminus may regulate the interaction with cytosolic phosphotyrosine binding (PTB) domain or Src homology 2 (SH2) domain containing proteins involved in cell signaling. We have recently described an interaction between tyrosine-phosphorylated CTFs and ShcA adaptor protein which is highly enhanced in AD brain, and a new interaction between APP and the adaptor protein Grb2 both in human brain and in neuroblastoma cultured cells. These data suggest a possible role in cell signaling for APP and its CTFs, in a manner similar to that previously reported for other receptors, through a tightly regulated coupling with intracellular adaptors to control the signaling of the cell. In this review, we discuss the significance of these novel findings for AD development.
