Background

Function：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)

Expression：
Tissue_specificity:Protein levels were detected in azurophilic granules of neutrophils and cytoplasmic granules of platelets (PubMed: 11987239) . It was also expressed in multiple tissues, including the brain, liver, spleen, and lymph nodes (PubMed: 7596406, PubMed: 8574969, PubMed: 8641442) .

Isoforms & Post-Translational Modification：P49768 has 7 isomers: P49768-1: 52668 Da (predicted); P49768-2: 52197 Da (predicted); P49768-3: 42287 Da (predicted); P49768-4: 21073 Da (predicted); P49768-5: 42757 Da (predicted); P49768-6: 46328 Da (predicted); P49768-7: 48997 Da (predicted).
Heterogeneous proteolytic processing generates N-terminal (NTF) and C-terminal (CTF) fragments of approximately 35 and 20 kDa, respectively. During apoptosis, the C-terminal fragment (CTF) is further cleaved by caspase-3 to produce the fragment, PS1-CTF12;After endoproteolysis, the C-terminal fragment (CTF) is phosphorylated on serine residues by PKA and/or PKC. Phosphorylation on Ser-346 inhibits endoproteolysis

Subunit：Homodimer. The functional gamma-secretase complex is composed of at least four polypeptides: a presenilin homodimer (PSEN1 or PSEN2), nicastrin (NCSTN), APH1 (APH1A/APH1B) and PEN2 (PubMed:12679784, PubMed:12740439, PubMed:15274632, PubMed:25043039, PubMed:25394380, PubMed:26280335, PubMed:30598546, PubMed:30630874). Such minimal complex is sufficient for secretase activity (PubMed:12679784, PubMed:12740439, PubMed:15274632, PubMed:25043039, PubMed:26280335, PubMed:30598546, PubMed:30630874). Other components which are associated with the complex include SLC25A64, SLC5A7, PHB and PSEN1 isoform 3. As part of the gamma-secretase complex, interacts with CRB2 (via transmembrane domain) (PubMed:20299451). Predominantly heterodimer of a N-terminal (NTF) and a C-terminal (CTF) endoproteolytical fragment (PubMed:15274632). Associates with proteolytic processed C-terminal fragments C83 and C99 of the amyloid precursor protein (APP) (via transmembrane domain) (PubMed:30630874). Associates with NOTCH1 (via transmembrane domain) (PubMed:10593990, PubMed:30598546). Associates with cadherin/catenin adhesion complexes through direct binding to CDH1 or CDH2 (PubMed:11953314, PubMed:14515347, PubMed:16126725). Interaction with CDH1 stabilizes the complex and stimulates cell-cell aggregation (PubMed:11953314). Interaction with CDH2 is essential for trafficking of CDH2 from the endoplasmic reticulum to the plasma membrane (PubMed:14515347). Interacts with CTNND2, CTNNB1, CTNND1, JUP, HERPUD1, FLNA, FLNB, MTCH1, PKP4 and PARL (PubMed:10037471, PubMed:10551805, PubMed:11799129, PubMed:11953314, PubMed:16126725, PubMed:9437013, PubMed:9738936). Interacts through its N-terminus with GFAP (isoform 2) (PubMed:12058025). Interacts with DOCK3 (By similarity). Interacts with isoform 1 and isoform 3 of UBQLN1 (PubMed:21143716)
