Background

Presenilin‑2 (PS-2 and PSEN2) is a catalytic subunit of the gamma-secretase complex. Presenilin‑2 may play a role in intracellular signaling and gene expression or in linking chromatin to the nuclear membrane. Heterogeneous proteolytic processing of Presenilin‑2 generates N-terminal (aa 1-297) and C-terminal (aa 298-248) fragments. Presenilin 1 and Presenilin 2 determine gamma-secretase activity, which is responsible for cleaving the amyloid precursor protein (APP). In turn, APP cleavage can produce amyloid-beta, which is the primary component of plaques in the brains of Alzheimer’s disease patients. Full length, approximately 50 kDa, and the approximately 30 kDa N-terminal fragment of Presenilin-2 were identified by western blotting in extracted rodent pancreas but only the 30 kDa fragment was detected in mouse islets and human insulinoma. Within a sequence correspondent to the immunogen, human PS-2 shares 87% aa sequence identity with mouse and rat PS-2.
