pubmed:abstractText |
Regulated intramembrane proteolysis (RIP) of the amyloid precursor protein (APP) produces amyloid beta-protein (Abeta), the probable causative agent of Alzheimer's disease (AD), and is therefore an important target for therapeutic intervention. However, there is a burgeoning consensus that gamma-secretase, one of the proteases that generates Abeta, is also critical for the signal transduction of APP and a growing list of other receptors. APP is a member of a gene family that includes two amyloid precursor-like proteins, APLP1 and APLP2. Although APP and the APLPs undergo similar proteolytic processing, there is little information about the role of their gamma-secretase-generated intracellular domains (ICDs). Here, we show that APLP1 and 2 undergo presenilin-dependent RIP similar to APP, resulting in the release of a approximately 6 kDa ICD for each protein. Each of the ICDs are degraded by an insulin degrading enzyme-like activity, but they can be stabilized by members of the FE65 family and translocate to the nucleus. Given that modulation of APP processing is a therapeutic target and that the APLPs are processed in a manner similar to APP, any strategy aimed at altering APP proteolysis will have to take into account possible effects on signaling by APLP 1 and 2.
