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 synapes 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.N-APP binds TNFRSF21 triggering caspase activation and degeneration of both neuronal cell bodies (via caspase-3) and axons (via caspase-6).

Activity summary

Beta Amyloid 1-42 often referred to as Abeta 42 or amyloid beta 1-42 is a peptide derived from the amyloid precursor protein (APP). This peptide consists of 42 amino acids and has a molecular weight of approximately 4.5 kDa. It is predominantly found in the brain especially within regions associated with memory and cognitive function. Beta amyloid 1-42 is a product of enzymatic cleavage by beta and gamma secretases from the larger APP molecule. Due to its aggregation-prone nature beta amyloid 1-42 is a focus in neuroscience research particularly concerning the formation of amyloid plaques.

Biological function summary

Amyloid beta 1-42 plays a central role in synaptic activity and neuronal health. While not inherently pathogenic its tendency to aggregate forms oligomers and fibrils which become toxic to neurons. This peptide contributes to synaptic dysfunction and neuronal cell death and is a major component of extracellular amyloid plaques found in brain tissue. Within the cellular environment amyloid beta 1-42 can interact with receptors membrane lipids and intracellular signaling mechanisms thereby affecting neuronal cell function.

Pathways

Amyloid beta 1-42 is important in the amyloidogenic pathway which is one of the critical components in APP processing. The pathway includes proteolytic enzymes like beta secretase (BACE1) and gamma secretase where misregulation may lead to excessive production or deposition of amyloid beta peptides. Another related pathway is the tau protein phosphorylation pathway which indirectly interacts with amyloid beta 1-42 due to shared signaling intermediates impacting tau stabilization and microtubule assembly in neurons.

Associated diseases and disorders

Amyloid beta 1-42 plays a pivotal role in Alzheimer's disease a prevalent neurodegenerative disorder. The excessive accumulation of beta amyloid in the form of plaques is a hallmark of the disease contributing to cognitive decline. Also it has links to cerebral amyloid angiopathy where it deposits in the walls of blood vessels of the central nervous system. Both conditions may involve interactions with tau protein another pathological feature of Alzheimer's disease which undergoes hyperphosphorylation leading to neurofibrillary tangles formation.
