Summary

The presenilin proteins are mutated in some patients with early onset Alzheimer's disease, but the function of these proteins is not known. Accumulating evidence suggests that they are g-secretase enzymes that process the amyloid precursor protein. Now, as Sisodia discusses in this Perspective, another protein called nicastrin has been discovered that may contribute to the g-secretase activity of the presenilins.
