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.

Notes

ab251335 is the carrier-free version of Anti-Amyloid Fibril antibody [mOC87] - Conformation-Specific ab201062.

This antibody was developed as part of a collaboration between Abcam and Professor Charles Glabe, UC Irvine.

ab251335 recognizes a generic epitope of amyloid fibrils and oligomers that is independent of linear sequence (Hatami et al 2014, PMID: 25281743). Its reactivity with Aß monomer and oligomers is decreased or eliminated upon thermal denaturation at 100°C of Aß in SDS sample buffer on western blots (Hatami et al 2014, PMID: 25281743).

For further information on the immunogen, please refer to Hatami et al 2014, PMID: 25281743 and

Activity summary

Amyloid fibrils alternatively named fibrillar amyloid are insoluble fibrous protein aggregates resulting from the abnormal folding of proteins. They compose primarily of beta-sheet structures which promote stability and rigidity. Amyloid fibrils are frequently associated with proteins like Aβ and tau known for their high molecular mass. Researchers observe these structures in various tissues where they exhibit significant resilience to both chemical and enzymatic degradation.

Biological function summary

The misfolding and accumulation of proteins into amyloid fibrils prove disruptive within cells. These aggregates often form as part of complex protein assemblies and interfere with normal cellular functions. This disruption further leads to cellular dysfunction and death. While commonly observed in neuronal cells where they are linked to neurodegenerative conditions amyloid fibrils can also appear in other tissues and organs suggesting multi-systemic implications.

Pathways

Scientists recognize amyloid fibrils for their involvement in the amyloidogenic pathways. These pathways often lead to the generation and accumulation of misfolded proteins. The amyloid precursor protein (APP) and presenilins play important roles in pathway processes associated with amyloid fibrils. In addition the fibrillar structures can influence calcium dysregulation and oxidative stress contributing to altered cellular homeostasis.

Associated diseases and disorders

Amyloid fibrils are strongly associated with Alzheimer's disease and systemic amyloidosis. Within Alzheimer's disease amyloid fibrils formed by Aβ peptides contribute to plaque formation a hallmark of the condition. Furthermore interactions with tau protein exacerbate neurofibrillary tangles compounding neurodegenerative effects. In systemic amyloidosis different precursor proteins undergo fibrillogenesis resulting in widespread organ dysfunction and highlighting the pathogenic potential of amyloid fibrils beyond neurological tissues.
