Some S100 proteins, including S100A13, are able to bind the cell surface receptor for advanced glycation endproducts (RAGE). Despite lacking a signal sequence, S100A13 plays an important role in Cu²⁺-dependent export of FGF-1 (FGF acidic) and IL-1 alpha from the cell in response to stresses such as heat shock, anoxia and starvation. Binding of copper is necessary for formation of a multiprotein complex between S100A13, FGF-1 and p40 synaptotagmin1 (syt1). Cu²⁺ ions supplied by S100A13 are thought to oxidize and downregulate the activity of FGF-1 prior to export. calcium influx may also play a similar role in FGF-1 release from neuronal cells. With FGF-1 and syt1, S100A13 likely perturbs the membrane, which allows the S100A13 protein complex to exit the cell. S100A13 has been proposed as a marker for angiogenesis in tumors and endometrium, due to its role in stress induced export of FGF-1.
