Gamma-secretase 'buckles up' to reach its destination

New research has uncovered the early assembly of gamma-secretase, a protein complex linked to numerous cellular processes including the development of Alzheimer's disease. In a first step, two dimeric subcomplexes are formed, which independently exit the ER and only afterwards assemble into a four-subunit complex. This 'buckle up' mechanism is thought to prevent premature assembly and activity.
