Cell surface pattern recognition receptor that senses endogenous stress signals with a broad ligand repertoire including advanced glycation end products, S100 proteins, high-mobility group box 1 protein/HMGB1, amyloid beta/APP oligomers, nucleic acids, phospholipids and glycosaminoglycans (PubMed:21270403, PubMed:32670276). Advanced glycosylation end products are nonenzymatically glycosylated proteins which accumulate in vascular tissue in aging and at an accelerated rate in diabetes. These ligands accumulate at inflammatory sites during the pathogenesis of various diseases, including diabetes, vascular complications, neurodegenerative disorders, and cancers and RAGE transduces their binding into pro-inflammatory responses. Upon ligand binding, uses TIRAP and MYD88 as adapters to transduce the signal ultimately leading to the induction or inflammatory cytokines IL6, IL8 and TNFalpha through activation of NF-kappa-B. Interaction with S100A12 on endothelium, mononuclear phagocytes, and lymphocytes triggers cellular activation, with generation of key pro-inflammatory mediators (By similarity). Interaction with S100B after myocardial infarction may play a role in myocyte apoptosis by activating ERK1/2 and p53/TP53 signaling (By similarity). Contributes to the translocation of amyloid-beta peptide (ABPP) across the cell membrane from the extracellular to the intracellular space in cortical neurons (PubMed:19901339). ABPP-initiated RAGE signaling, especially stimulation of p38 mitogen-activated protein kinase (MAPK), has the capacity to drive a transport system delivering ABPP as a complex with RAGE to the intraneuronal space. Participates in endothelial albumin transcytosis together with HMGB1 through the RAGE/SRC/Caveolin-1 pathway, leading to endothelial hyperpermeability (By similarity). Mediates the loading of HMGB1 in extracellular vesicles (EVs) that shuttle HMGB1 to hepatocytes by transferrin-mediated endocytosis and subsequently promote hepatocyte pyroptosis by activating the NLRP3 inflammasome (By similarity). Promotes also extracellular hypomethylated DNA (CpG DNA) uptake by cells via the endosomal route to activate inflammatory responses (By similarity).
Isoform 2
Is able to advanced glycosylation end product (AGE)-induce nuclear factor NF-kappa-B activation.
Isoform 10
Down-regulates receptor for advanced glycosylation end products (RAGE)-ligand induced signaling through various MAPK pathways including ERK1/2, p38 and SAPK/JNK. Significantly affects tumor cell properties through decreasing cell migration, invasion, adhesion and proliferation, and increasing cellular apoptosis. Exhibits drastic inhibition on tumorigenesis in vitro.
Phosphorylated on its cytoplasmic domain by PKCzeta/PRKCZ upon ligand binding.
Targeted by the ubiquitin E3 ligase subunit FBXO10 to mediate its ubiquitination and degradation.
Isoform 1: Expressed at higher levels in the coronary arterioles in type 2 diabetic mice (at protein level). Endothelial cells (PubMed:18539754). Expressed in lung, kidney, brain and heart. Most prevalent isoform with the highest level in heart (PubMed:19164451). Isoform 2: Expressed in brain, lung, kidney and small intestine with the highest level in lung. Expressed in brain, lung, kidney and small intestine with the highest level in small intestine (at protein level). Detected in neurons of the cerebrum, bronchial epithelium, endothelial cells, tubular cells of kidney and epithelial cells of small intestine (at protein level).
