AGER Protein, Human (HEK293, hFc)

AGER proteins are cell surface pattern recognition receptors that expertly sense endogenous stress signals utilizing an extensive library of ligands, including advanced glycation end products, S100 proteins, high mobility Group Box 1 proteins/HMGB1, starch Like protein β/APP oligomers, nucleic acids, phospholipids, and glycosaminoglycans. AGER Protein, Human (HEK293, hFc) is the recombinant human-derived AGER protein, expressed by HEK293 , with C-hFc labeled tag. The total length of AGER Protein, Human (HEK293, hFc) is 321 a.a., with molecular weight of approximately 76.18 kDa.

AGER Protein, a cell surface pattern recognition receptor, adeptly senses endogenous stress signals with a wide-ranging ligand repertoire, encompassing advanced glycation end products, S100 proteins, high-mobility group box 1 protein/HMGB1, amyloid beta/APP oligomers, nucleic acids, phospholipids, and glycosaminoglycans. Accumulation of advanced glycosylation end products, especially prevalent in aging and diabetes, triggers inflammatory responses at various disease sites, including diabetes, vascular complications, neurodegenerative disorders, and cancers. RAGE, upon ligand binding, utilizes TIRAP and MYD88 as adapters to transduce signals, ultimately inducing inflammatory cytokines IL6, IL8, and TNFalpha through NF-kappa-B activation. Noteworthy interactions include S100A12-triggered cellular activation, S100B-induced apoptosis post-myocardial infarction, and the facilitation of amyloid-beta peptide translocation in cortical neurons. AGER also plays a role in endothelial albumin transcytosis with HMGB1 through the RAGE/SRC/Caveolin-1 pathway, leading to endothelial hyperpermeability, and mediates the loading of HMGB1 in extracellular vesicles for hepatocyte pyroptosis via the NLRP3 inflammasome. Additionally, it promotes extracellular hypomethylated DNA uptake for the activation of inflammatory responses. The constitutive homodimeric and oligomeric forms, along with interactions with S100 proteins, APP, TIRAP, and HMGB1, highlight the intricate involvement of AGER Protein in various cellular processes and pathological conditions.

1.Immobilized Human AGER at 20 μg/mL (100 μL/well) can bind Biotinylated Human HMGB1.The ED₅₀ for this effect is 30.85 ng/mL, corresponding to a specific activity is 3.24×10⁴ Unit/mg.
2.Measured by its binding ability in a functional ELISA. Immobilized human S100A12 at 2 μg/mL (100 μl/well) can bind recombinant human AGER with a linear range of 0.032-20 μg/mL.
