NCIt definition : Presenilin-2 (448 aa, 50 kDa) is encoded by the human PSEN2 gene. This protein is
involved in proteolytic processing.;
NCIt note : Presenilin-2 is autocatalytically processed, which generates an amino terminal fragment
(NTF) and a carboxyl terminal fragment (CTF). The NTF and CTF are maintained as a
disulfide-linked heterodimer. This cleavage is required for gamma secretase activity.;
