Several specific topics on recent findings in the studies of memapsin 2 (β-secretase) are discussed in this article. New structural evidence on memapsin 2 has pointed to the structural basis of flap opening. Such a mechanism is thought to participate in the substrate sequence selection during the cellular function. Another potentially important area is the intracellular transport of memapsin 2. Here we discuss the involvement of APP in memapsin 2 endocytosis and the GGA proteins in recycling the protease back to the cell surface. These mechanisms may be connected with the cellular regulation of neuronal activity through the regulation of memapsin 2 activity and Aβ production.
