The present invention provides methods and compositions for modulating levels of amyloid-&bgr; peptide (A&bgr;) exhibited by cells or tissues. The invention also provides pharmaceutical compositions and methods of screening for compounds that modulate A&bgr; levels. The invention also provides modulation of A&bgr; levels via selective modulation (e.g., inhibition) of ATP-dependent &ggr;-secretase activity. The invention also provides methods of preventing, treating or ameliorating the symptoms of a disorder, including but not limited to an A&bgr;-related disorder, by administering a modulator of &ggr;-secretase, including, but not limited to, a selective inhibitor of ATP-dependent &ggr;-secretase activity or an agent that decreases the formation of active (or optimally active) &ggr;-secretase. The invention also provides the use of inhibitors of ATP-dependent &ggr;-secretase activity to prevent, treat or ameliorate the symptoms of Alzheimer's disease.
