Abstract |
Alzheimer's disease (AD) is characterized by cerebral deposition of beta-amyloid (Abeta) peptides. Abeta is released from ectodomain cleaved amyloid precursor protein (APP) via intramembranous proteolysis by gamma-secretase, a complex consisting of presenilin and a few other proteins. p23/TMP21, a member of the p24 family type I transmembrane proteins, was recently identified as a presenilin complex component capable of modulating gamma-secretase cleavage. The p24 family proteins form oligomeric complexes and regulate vesicular trafficking in the early secretory pathway, but their role in APP trafficking has not been investigated. |
