Protein Information
Name PSEN2
Synonyms AD4, PS2, PSNL2, STM2
Function Probable catalytic subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (beta-amyloid precursor protein). Requires the other members of the gamma-secretase complex to have a protease activity. May play a role in intracellular signaling and gene expression or in linking chromatin to the nuclear membrane. May function in the cytoplasmic partitioning of proteins.
Cellular Location Endoplasmic reticulum membrane; Multi-pass membrane protein. Golgi apparatus membrane; Multi-pass membrane protein
Tissue Location Isoform 1 is seen in the placenta, skeletal muscle and heart while isoform 2 is seen in the heart, brain, placenta, liver, skeletal muscle and kidney

Presenilin 1 (PS1) and Presenilin 2 (PS2) are transmembrane proteins which belong to Presenilin family, and their mutations are associated with early onset familial Alzheimer's disease. Presenilins facilitate gamma-secretase cleavage of the beta-amyloid precursor protein and the intramembraneous cleavage of Notch1 (1). Phosphorylation of the PS2 C-terminal fragments at serine residues 327 and 330, located immediately adjacent to the caspase recognition sites, inhibits caspase-mediated cleavage of PS2 and can regulate apoptotic cleavage. PS2 is cleaved by caspases during apoptosis between aspartate 329 and serine 330 (2).
