Alteration of β-secretase traffic by the receptor tyrosine kinase signaling pathway - a new mechanism for regulating Alzheimer＇s β-amyloid production

The receptor tyrosine kinases （RTKs） are a family of cell surface proteins with diverse functions in proliferation, differentiation or cell-cell communication. When a specific ligand binds to its cognate receptor, a conformational change of this receptor due to the ligand-receptor interaction will lead to activation of the intrinsic tyrosine kinase residing in the intracellular domain of the receptor. The activation of this tyrosine kinase is essential for transducing the signals to a cascade of its downstream molecules that eventually cause related physiological responses .
