CC   -!- FUNCTION: Catalytic subunit of the gamma-secretase complex, an
CC       endoprotease complex that catalyzes the intramembrane cleavage of
CC       integral membrane proteins such as Notch receptors and APP (amyloid-
CC       beta precursor protein). Selectively cleaves late endosomal/lysosomal
CC       localized substrates and generates the prominent pool of intracellular
CC       amyloid beta that contains longer amyloid beta. The holoprotein
CC       functions as a calcium-leak channel that allows the passive movement of
CC       calcium from endoplasmic reticulum to cytosol and is involved in
CC       calcium homeostasis. Is a regulator of mitochondrion-endoplasmic
CC       reticulum membrane tethering and modulates calcium ions shuttling
CC       between ER and mitochondria. {ECO:0000256|ARBA:ARBA00094320}.
CC   -!- SUBUNIT: Homodimer; predominantly heterodimer of a N-terminal (NTF) and
CC       a C-terminal (CTF) endoproteolytical fragment. Component of the gamma-
CC       secretase complex, a complex composed of a presenilin homodimer (PSEN1
CC       or PSEN2), nicastrin (NCSTN), APH1 (APH1A or APH1B) and PSENEN. Such
CC       minimal complex is sufficient for secretase activity, although other
CC       components may exist. Interacts with DOCK3. Interacts with HERPUD1,
CC       FLNA, FLNB and PARL. Interacts with AP1G1; this interaction is
CC       phosphorylation dependent and directs PSEN2 via early endosome to late
CC       endosome/lysosome. {ECO:0000256|ARBA:ARBA00094601}.
