Function
Functions as a cell surface receptor and performs physiological functions on the surface of neurons relevant to neurite growth, neuronal adhesion and axonogenesis. Interaction between APP molecules on neighboring cells promotes synaptogenesis (PubMed:25122912). Involved in cell mobility and transcription regulation through protein-protein interactions. Can promote transcription activation through binding to APBB1-KAT5 and inhibits Notch signaling through interaction with Numb. Couples to apoptosis-inducing pathways such as those mediated by G(o) and JIP. Inhibits G(o) alpha ATPase activity (By similarity). Acts as a kinesin I membrane receptor, mediating the axonal transport of beta-secretase and presenilin 1 (By similarity). By acting as a kinesin I membrane receptor, plays a role in axonal anterograde transport of cargo towards synapses in axons (PubMed:17062754, PubMed:23011729). Involved in copper homeostasis/oxidative stress through copper ion reduction. In vitro, copper-metallated APP induces neuronal death directly or is potentiated through Cu(2+)-mediated low-density lipoprotein oxidation. Can regulate neurite outgrowth through binding to components of the extracellular matrix such as heparin and collagen I and IV. The splice isoforms that contain the BPTI domain possess protease inhibitor activity. Induces a AGER-dependent pathway that involves activation of p38 MAPK, resulting in internalization of amyloid-beta peptide and leading to mitochondrial dysfunction in cultured cortical neurons. Provides Cu(2+) ions for GPC1 which are required for release of nitric oxide (NO) and subsequent degradation of the heparan sulfate chains on GPC1.Amyloid-beta peptides are lipophilic metal chelators with metal-reducing activity. Bind transient metals such as copper, zinc and iron. In vitro, can reduce Cu(2+) and Fe(3+) to Cu(+) and Fe(2+), respectively. Amyloid-beta protein 42 is a more effective reductant than amyloid-beta protein 40. Amyloid-beta peptides bind to lipoproteins and apolipoproteins E and J in the CSF and to HDL particles in plasma, inhibiting metal-catalyzed oxidation of lipoproteins. APP42-beta may activate mononuclear phagocytes in the brain and elicit inflammatory responses. Promotes both tau aggregation and TPK II-mediated phosphorylation. Interaction with overexpressed HADH2 leads to oxidative stress and neurotoxicity. Also binds GPC1 in lipid rafts.Appicans elicit adhesion of neural cells to the extracellular matrix and may regulate neurite outgrowth in the brain.The gamma-CTF peptides as well as the caspase-cleaved peptides, including C31, are potent enhancers of neuronal apoptosis.

Supplementary info

- Activity summary
The Amyloid Precursor Protein (APP) also known as amyloid protein is a transmembrane protein that is approximately 695 to 770 amino acids in length depending on the isoform. The molecular mass of APP can vary but typically falls around 100 to 140 kDa. It is heavily expressed in the central nervous system particularly in neurons but also in other tissues like muscle and kidney. The APP undergoes proteolytic processing which leads to the generation of various fragments including beta-amyloid peptides.
- Biological function summary
The processing of APP plays a fundamental role in neuronal growth survival and repair. APP is cleaved into fragments that can regulate synaptic function and plasticity. It does not operate as a part of a complex but interacts with various cellular components. The protein participates in signaling pathways influencing cellular adhesion motility and neurite outgrowth. APP’s numerous interaction partners facilitate its involvement in different cellular processes highlighting its critical role in normal cell function.
- Pathways
The APP is a central component in the amyloidogenic pathway where its cleavage by beta-secretase and gamma-secretase yields beta-amyloid. This pathway is one of two primary metabolic routes for APP—alternative enzymatic processing through the non-amyloidogenic pathway precludes beta-amyloid formation releasing peptides that do not aggregate. Enzymes like BACE1 (beta-secretase 1) and presenilin are important in the amyloidogenic pathway directly resulting in the production of the neurotoxic amyloid beta-peptide.
- Associated diseases and disorders
APP is intensely linked to Alzheimer's disease and cerebral amyloid angiopathy. Accumulation of beta-amyloid peptides formed from APP cleavage is a hallmark of Alzheimer's disease leading to plaque formation in the brain. This aggregation impacts neuronal function and is associated with neurodegenerative processes. Interactions with proteins like tau are significant as tau also plays an essential role in Alzheimer's disease pathology. Misprocessing of APP and the resulting beta-amyloid aggregates are also contributors to cerebral amyloid angiopathy where deposits within cerebrovascular walls compromise vascular integrity.
