Function
RAGE_HUMAN Mediates interactions of advanced glycosylation end products (AGE). These are nonenzymatically glycosylated proteins which accumulate in vascular tissue in aging and at an accelerated rate in diabetes. Acts as a mediator of both acute and chronic vascular inflammation in conditions such as atherosclerosis and in particular as a complication of diabetes. AGE/RAGE signaling plays an important role in regulating the production/expression of TNF-alpha, oxidative stress, and endothelial dysfunction in type 2 diabetes. Interaction with S100A12 on endothelium, mononuclear phagocytes, and lymphocytes triggers cellular activation, with generation of key proinflammatory mediators. Interaction with S100B after myocardial infarction may play a role in myocyte apoptosis by activating ERK1/2 and p53/TP53 signaling (By similarity). Receptor for amyloid beta peptide. Contributes to the translocation of amyloid-beta peptide (ABPP) across the cell membrane from the extracellular to the intracellular space in cortical neurons. 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.[1]
Publication Abstract from PubMed
S100 proteins are calcium-dependent regulators of homeostatic processes. Upon cellular response to stress, and notably during tumorigenesis, they relocalize to the extracellular environment where they induce pro-inflammatory signals by activating the receptor for advanced glycation end products (RAGE), thereby facilitating tumor growth and metastasis. Despite its importance in sustaining inflammation, the structural basis for RAGE-S100 crosstalk is still unknown. Here we report two crystal structures of the RAGE:S100A6 complex encompassing a full-length RAGE ectodomain. The structures, in combination with a comprehensive interaction analysis, suggest that the primary S100A6 binding site is formed by the RAGE C1 domain. Complex formation with S100A6 induces a unique dimeric conformation of RAGE that appears suited for signal transduction and intracellular effector recruitment. Intriguingly, S100A6 adopts a dimeric conformation radically different from all known S100 dimers. We discuss the physiological relevance of this non-canonical homodimeric form in vivo.
