Protein twists and turns in Alzheimer disease

Nature Medicine volume 12, pages 392–393 (2006)Cite this article

An enzyme that modifies protein structure seems to help keep Alzheimer disease at bay. The enzyme affects two proteins thought to be key to disease pathology: amyloid precursor protein (APP) and the microtubule-binding protein tau.

Research on Alzheimer disease has been driven by a focus on two proteins, tau and APP, thought to underlie the affliction. Brains of affected individuals accumulate aberrant forms of both of these proteins: tau becomes hyperphosphorylated and accumulates in neuritic aggregates and APP is cleaved to produce amyloid-β (Aβ) protein aggregates1.
