CC -!- FUNCTION: Functions as a cell surface receptor and performs
CC physiological functions on the surface of neurons relevant to neurite
CC growth, neuronal adhesion and axonogenesis. Interaction between APP
CC molecules on neighboring cells promotes synaptogenesis. Involved in
CC cell mobility and transcription regulation through protein-protein
CC interactions (By similarity). Can promote transcription activation
CC through binding to APBB1-KAT5 and inhibit Notch signaling through
CC interaction with Numb (By similarity). Couples to apoptosis-inducing
CC pathways such as those mediated by G(o) and JIP (By similarity).
CC Inhibits G(o)-alpha ATPase activity (By similarity). Acts as a kinesin
CC I membrane receptor, mediating the axonal transport of beta-secretase
CC and presenilin 1 (By similarity). By acting as a kinesin I membrane
CC receptor, plays a role in axonal anterograde transport of cargo towards
CC synapes in axons (By similarity). May be involved in copper
CC homeostasis/oxidative stress through copper ion reduction (By
CC similarity). In vitro, copper-metallated APP induces neuronal death
CC directly or is potentiated through Cu(2+)-mediated low-density
CC lipoprotein oxidation (By similarity). Can regulate neurite outgrowth
CC through binding to components of the extracellular matrix such as
CC heparin and collagen I and IV. Induces a AGER-dependent pathway that
CC involves activation of p38 MAPK, resulting in internalization of
CC amyloid-beta peptide and mitochondrial dysfunction in cultured cortical
CC neurons. Provides Cu(2+) ions for GPC1 which are required for release
CC of nitric oxide (NO) and subsequent degradation of the heparan sulfate
CC chains on GPC1 (By similarity). {ECO:0000250,
CC ECO:0000250|UniProtKB:P05067}.
CC -!- FUNCTION: Amyloid-beta peptides are lipophilic metal chelators with
CC metal-reducing activity. Binds transient metals such as copper, zinc
CC and iron (By similarity). {ECO:0000250}.
CC -!- FUNCTION: The gamma-CTF peptides as well as the caspase-cleaved
CC peptides, including C31, are potent enhancers of neuronal apoptosis.
CC {ECO:0000250}.
CC -!- FUNCTION: N-APP binds TNFRSF21 triggering caspase activation and
CC degeneration of both neuronal cell bodies (via caspase-3) and axons
CC (via caspase-6). {ECO:0000250}.
CC -!- SUBUNIT: Binds, via its C-terminus, to the PID domain of several
CC cytoplasmic proteins, including APBB family members, the APBA family,
CC MAPK8IP1, SHC1 and NUMB and DAB1 (By similarity). Binding to DAB1
CC inhibits its serine phosphorylation (By similarity). Interacts (via
CC NPXY motif) with DAB2 (via PID domain); the interaction is impaired by
CC tyrosine phosphorylation of the NPXY motif. Also interacts with GPCR-
CC like protein BPP, APPBP1, IB1, KNS2 (via its TPR domains), APPBP2 (via
CC BaSS) and DDB1. In vitro, it binds MAPT via the MT-binding domains (By
CC similarity). Associates with microtubules in the presence of ATP and in
CC a kinesin-dependent manner (By similarity). Interacts, through a C-
CC terminal domain, with GNAO1. Amyloid-beta protein 42 binds CHRNA7 in
CC hippocampal neurons (By similarity). Amyloid-beta associates with HADH2
CC (By similarity). Interacts with CPEB1, ANKS1B, TNFRSF21 and AGER (By
CC similarity). Interacts with ITM2B. Interacts with ITM2C. Interacts with
CC IDE. Can form homodimers; dimerization is enhanced in the presence of
CC Cu(2+) ions. Can form homodimers; this is promoted by heparin binding
CC (By similarity). Amyloid-beta protein 40 interacts with S100A9 (By
CC similarity). CTF-alpha product of APP interacts with GSAP (By
CC similarity). Isoform APP695 interacts with SORL1 (via N-terminal
CC ectodomain); this interaction retains APP in the trans-Golgi network
CC and reduces processing into soluble APP-alpha and amyloid-beta peptides
CC (By similarity). Isoform APP770 interacts with SORL1 (By similarity).
CC The C99 fragment also interacts with SORL1 (By similarity). Interacts
CC with PLD3 (By similarity). Interacts with VDAC1 (By similarity).
CC Interacts with NSG1; could regulate APP processing (By similarity).
CC Amyloid-beta protein 42 interacts with FPR2 (By similarity). Interacts
CC (via transmembrane region) with PSEN1; the interaction is direct (By
CC similarity). Interacts with LRRK2 (By similarity). Interacts (via
CC cytoplasmic domain) with KIF5B (By similarity). Interacts (via C-
CC terminus) with APBB2/FE65L1 (via C-terminus) (By similarity). Interacts
CC (via intracellular domain) with APBB3 (By similarity).

CC {ECO:0000250|UniProtKB:P05067}. Note=Cell surface protein that rapidly
CC becomes internalized via clathrin-coated pits. Only a minor proportion
CC is present at the cell membrane; most of the protein is present in
CC intracellular vesicles. During maturation, the immature APP (N-
CC glycosylated in the endoplasmic reticulum) moves to the Golgi complex
CC where complete maturation occurs (O-glycosylated and sulfated). After
CC alpha-secretase cleavage, soluble APP is released into the
CC extracellular space and the C-terminal is internalized to endosomes and
CC APP sorts to the basolateral surface in epithelial cells. During
CC neuronal differentiation, the Thr-743 phosphorylated form is located
CC mainly in growth cones, moderately in neurites and sparingly in the
CC cell body. Casein kinase phosphorylation can occur either at the cell
CC surface or within a post-Golgi compartment. Associates with GPC1 in
CC perinuclear compartments. Colocalizes with SORL1 in a vesicular pattern
CC in cytoplasm and perinuclear regions. {ECO:0000250|UniProtKB:P05067}.

CC phosphorylated Thr-743 form is localized to the nucleus (By
CC similarity). {ECO:0000250|UniProtKB:P05067,

CC -!- DOMAIN: The transmembrane helix undergoes a conformation change and
CC unravels partially when bound to PSEN1, facilitating cleavage by PSEN1.
CC {ECO:0000250|UniProtKB:P05067}.
CC -!- DOMAIN: The basolateral sorting signal (BaSS) is required for sorting
CC of membrane proteins to the basolateral surface of epithelial cells.
CC {ECO:0000250|UniProtKB:P05067}.
CC -!- DOMAIN: The GFLD subdomain binds Cu(2+) ions; this promotes
CC homodimerization. {ECO:0000250|UniProtKB:P05067}.
CC -!- DOMAIN: The NPXY sequence motif found in many tyrosine-phosphorylated
CC proteins is required for the specific binding of the PID domain.
CC However, additional amino acids either N- or C-terminal to the NPXY
CC motif are often required for complete interaction. The PID domain-
CC containing proteins which bind APP require the YENPTY motif for full
CC interaction. These interactions are independent of phosphorylation on
CC the terminal tyrosine residue. The YENPXY site is also involved in
CC clathrin-mediated endocytosis. {ECO:0000250|UniProtKB:P05067}.
CC -!- DOMAIN: The C-terminal region can bind zinc ions; this favors
CC dimerization and formation of higher oligomers.
CC {ECO:0000250|UniProtKB:P05067}.
CC -!- DOMAIN: The OX-2 motif shows some similarity to a region in the N-
CC terminus of CD200/MOX2. {ECO:0000250|UniProtKB:P05067}.
CC -!- PTM: Proteolytically processed under normal cellular conditions.
CC Cleavage either by alpha-secretase, beta-secretase or theta-secretase
CC leads to generation and extracellular release of soluble APP peptides,
CC S-APP-alpha and S-APP-beta, and the retention of corresponding
CC membrane-anchored C-terminal fragments, C80, C83 and C99. Subsequent
CC processing of C80 and C83 by gamma-secretase yields P3 peptides. This
CC is the major secretory pathway and is non-amyloidogenic. Alternatively,
CC presenilin/nicastrin-mediated gamma-secretase processing of C99
CC releases the amyloid-beta proteins, amyloid-beta protein 40 and
CC amyloid-beta protein 42, major components of amyloid plaques, and the
CC cytotoxic C-terminal fragments, gamma-CTF(50), gamma-CTF(57) and gamma-
CC CTF(59). PSEN1 cleavage is more efficient with C83 than with C99 as
CC substrate (in vitro). Amyloid-beta protein 40 and Amyloid-beta protein
CC 42 are cleaved by ACE. Many other minor amyloid-beta peptides, amyloid-
CC beta 1-X peptides, are found in cerebral spinal fluid (CSF) including
CC the amyloid-beta X-15 peptides, produced from the cleavage by alpha-
CC secretase. {ECO:0000250|UniProtKB:P05067}.
CC -!- PTM: Proteolytically cleaved by caspases during neuronal apoptosis.
CC Cleavage at Asp-739 by either caspase-3, -8 or -9 results in the
CC production of the neurotoxic C31 peptide and the increased production
CC of amyloid-beta peptides. {ECO:0000250}.
CC -!- PTM: N- and O-glycosylated. {ECO:0000250}.
CC -!- PTM: Phosphorylation in the C-terminal on tyrosine, threonine and
CC serine residues is neuron-specific. Phosphorylation can affect APP
CC processing, neuronal differentiation and interaction with other
CC proteins. Phosphorylated on Thr-743 in neuronal cells by Cdc5 kinase
CC and Mapk10, in dividing cells by Cdc2 kinase in a cell-cycle dependent
CC manner with maximal levels at the G2/M phase and, in vitro, by GSK-3-
CC beta. The Thr-743 phosphorylated form causes a conformational change
CC which reduces binding of Fe65 family members. In dopaminergic (DA)
CC neurons, phosphorylation on Thr-743 by LRKK2 promotes the production
CC and the nuclear translocation of the APP intracellular domain (AICD)
CC which induces DA neuron apoptosis. Phosphorylation on Tyr-757 is
CC required for SHC binding. Phosphorylated in the extracellular domain by
CC casein kinases on both soluble and membrane-bound APP. This
CC phosphorylation is inhibited by heparin.
CC {ECO:0000250|UniProtKB:P05067}.
CC -!- PTM: Trophic-factor deprivation triggers the cleavage of surface APP by
CC beta-secretase to release sAPP-beta which is further cleaved to release
CC an N-terminal fragment of APP (N-APP). {ECO:0000250}.
CC -!- PTM: Amyloid-beta peptides are degraded by IDE.
CC {ECO:0000250|UniProtKB:P12023}.
CC -!- PTM: Sulfated on tyrosine residues. {ECO:0000250|UniProtKB:P05067}.
CC -!- MISCELLANEOUS: Chelation of metal ions, notably copper, iron and zinc,
CC can induce histidine-bridging between amyloid-beta molecules resulting
CC in amyloid-beta-metal aggregates. Extracellular zinc-binding increases
CC binding of heparin to APP and inhibits collagen-binding.
CC {ECO:0000250|UniProtKB:P05067}.
CC -!- SIMILARITY: Belongs to the APP family. {ECO:0000255|PROSITE-
CC ProRule:PRU01217}.
