Advanced glycosylation endproduct receptor signaling (Homo sapiens)
From WikiPathways
Description
Advanced Glycosylation End- product-specific Receptor (AGER) also known as Receptor for Advanced Glycation End-products (RAGE) is a multi-ligand membrane receptor belonging to the immunoglobulin superfamily. It is considered to be a Pattern Recognition Receptor (Liliensiek et al. 2004). It recognizes a large variety of modified proteins known as advanced glycation/glycosylation endproducts (AGEs), a heterogenous group of structures that are generated by the Maillard reaction, a consequence of long-term incubation of proteins with glucose (Ikeda et al. 1996). Their accumulation is associated with diabetes, atherosclerosis, renal failure and ageing (Schmidt et al. 1999). The most prevalent class of AGE in vivo are N(6)-carboxymethyllysine (NECML) adducts (Kislinger et al. 1991). In addition to AGEs, AGER is a signal transduction receptor for amyloid-beta peptide (Ab) (Yan et al. 1996), mediating Ab neurotoxicity and promoting Ab influx into the brain. AGER also responds to the proinflammatory S100/calgranulins (Hofmann et al. 1999) and High mobility group protein B1 (HMGB1/Amphoterin/DEF), a protein linked to neurite outgrowth and cellular motility (Hori et al. 1995).
The major inflammatory pathway stimulated by AGER activation is NFkappaB. Though the signaling cascade is unclear, several pieces of experimental data suggest that activation of AGER leads to sustained activation and upregulation of NFkappaB, measured as NFkappaB translocation to the nucleus, and increased levels of de novo synthesized NFkappaB (Bierhaus et al. 2001). As this is clearly an indirect effect it is represented here as positive regulation of NFkappaB translocation to the nucleus. AGER can bind ERK1/2 and thereby activate the MAPK and JNK cascades (Bierhaus et al. 2005). View original pathway at:Reactome.

| R-HSA-879358 (Reactome) | In addition to AGER/RAGE, several other proteins have been identified as AGE-binding proteins. AGE binding proteins p60 and p90 (Yang et al. 1991) were subsequently identified as the Oligosaccharyl transferase 48 kDa subunit (Ost-48) and Glucosidease-2 subunit beta (Li et al. 1996). A third member was identified as Galectin-3 (Vlassara et al. 1995). These 3 proteins have been shown to be present on the plasma membrane of many cell types including vascular endothelium (Stitt et al. 1999). They have been designated AGE-R1, -R2 and -R3. Their suggested function is the removal and degradation of AGEs, but AGER-1 was found to negatively regulate AGER/RAGE (Lu et al. 2004), with kinetics that suggested a more complex interaction than simple competition for the same ligand. | |||
| R-HSA-879362 (Reactome) | Binding of ligand to AGER results in the activation of multiple signaling pathways, including the mitogen-activated protein kinase (MAPK) cascade (Lander et al. 1997), cdc42/Rac (Huttunen et al. 1999), and activation of NF-?B (Tanaka et al. 2000). A membrane-proximal cytoplasmic region of the advanced glycation end-products receptor (AGER) is responsible for binding to extracellular signal-regulated protein kinase-1 and -2 (ERK1/2 or MAPK3/1). This region is similar to the D-domain, an ERK docking site which is conserved in some ERK substrates (Ishihara et al. 2003). | |||
| R-HSA-879377 (Reactome) | The TRTK-12 fragment of the F-actin capping protein alpha subunit binds S100B in a calcium dependent manner. S100B undergoes a conformational change that is required for subsequent binding to effector proteins (Inman et al. 2002). S100B is a ligand for AGER (Hofmann et al. 1999). In addition this interaction between S100B andF-actin capping protein alpha could be important for regulating actin filament extension (Ivenkov et al. 1995). | |||
