The generation of nuclear signaling proteins by regulated intramembrane proteolysis (RIP) is a new paradigm of signal transduction. Mammalian proteins that are processed by RIP include SREBP-1, Notch-1, amyloid precursor protein (APP), and ErbB-4. Intramembranous γ-secretase cleavage of APP plays a central role in Alzheimer's disease by generating the amyloid β protein. An intriguing possibility is that the cognate C-terminal fragment generated by γ-secretase cleavage could also play a role through the regulation of nuclear signaling events. Thus, RIP may contribute to both brain development and degeneration and may provide unexpected diversity to the signaling repertoire of a cell.
