This study provides experimental support for the mechanism of proximity-mediated catalysis by a mitogenactivated protein (MAP) kinase. It describes how the transcription factor Ets-1 uses the cumulative effects of two suboptimal docking interactions, rather than a single canonical docking interaction, to enable a unique bipartite mechanism of recognition of the MAP kinase ERK2. This mode of interaction between Ets-1 and ERK2 facilitates the formation of a highly productive complex that not only
