N2 - The function of S100A4, a member of the calcium-binding S100 protein family, has been associated with tumor invasion and metastasis. Although an essential pro-metastatic role of extracellular S100A4 in tumor progression has been demonstrated, the identification of the precise underlying mechanisms and protein partners (receptors) has remained elusive. To identify putative targets for extracellular S100A4, we screened a phage display peptide library using S100A4 as bait. We identified three independent peptide motifs with varying affinities for the S100A4 protein. Sequence analyses indicated that the most abundant peptide mimicked the F/YCC motif present in the epidermal growth factor domain of ErbB receptor ligands. S100A4 selectively interacted with a number of epidermal growth factor receptor (EGFR) ligands, demonstrating highest affinity for amphiregulin. Importantly, we found that S100A4 stimulated EGFR/ErbB2 receptor signaling and enhanced the amphiregulin-mediated proliferation of mouse embryonic fibroblasts. S100A4-neutralizing antibodies, as well as EGFR- and ErbB2 receptor-specific tyrosine kinase inhibitors, blocked these effects. The present results suggest that extracellular S100A4 regulates tumor progression by interacting with EGFR ligands, thereby enhancing EGFR/ErbB2 receptor signaling and cell proliferation.
