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 (amyloid-beta precursor protein) (PubMed : 10206644, PubMed : 10545183, PubMed : 10593990, PubMed : 10811883, PubMed : 10899933, PubMed : 12679784, PubMed : 12740439, PubMed : 15274632, PubMed : 20460383, PubMed : 25043039, PubMed : 26280335, PubMed : 28269784, PubMed : 30598546, PubMed : 30630874). Requires the presence of the other members of the gamma-secretase complex for protease activity (PubMed : 15274632, PubMed : 25043039, PubMed : 26280335, PubMed : 30598546, PubMed : 30630874). Plays a role in Notch and Wnt signaling cascades and regulation of downstream processes via its role in processing key regulatory proteins, and by regulating cytosolic CTNNB1 levels (PubMed : 10593990, PubMed : 10811883, PubMed : 10899933, PubMed : 9738936). Stimulates cell-cell adhesion via its interaction with CDH1; this stabilizes the complexes between CDH1 (E-cadherin) and its interaction partners CTNNB1 (beta-catenin), CTNND1 and JUP (gamma-catenin) (PubMed : 11953314). Under conditions of apoptosis or calcium influx, cleaves CDH1 (PubMed : 11953314). This promotes the disassembly of the complexes between CDH1 and CTNND1, JUP and CTNNB1, increases the pool of cytoplasmic CTNNB1, and thereby negatively regulates Wnt signaling (PubMed : 11953314, PubMed : 9738936). Required for normal embryonic brain and skeleton development, and for normal angiogenesis (By similarity). Mediates the proteolytic cleavage of EphB2/CTF1 into EphB2/CTF2 (PubMed : 17428795, PubMed : 28269784). The holoprotein functions as a calcium-leak channel that allows the passive movement of calcium from endoplasmic reticulum to cytosol and is therefore involved in calcium homeostasis (PubMed : 16959576, PubMed : 25394380). Involved in the regulation of neurite outgrowth (PubMed : 15004326, PubMed : 20460383). Is a regulator of presynaptic facilitation, spike transmission and synaptic vesicles replenishment in a process that depends on gamma-secretase activity. It acts through the control of SYT7 presynaptic expression (By similarity).
