Paradoxical activation of the protein kinase-transcription factor ERK5 by ERK5 kinase inhibitors

Selective ERK5 inhibitors target ERK5 kinase activity, but they do not phenocopy the effects of ERK5 genetic depletion. Here, the authors demonstrate that the direct interaction of these inhibitors to ERK5 kinase domain induces conformational changes that promote ERK5 nuclear translocation and trans...

Summary:Selective ERK5 inhibitors target ERK5 kinase activity, but they do not phenocopy the effects of ERK5 genetic depletion. Here, the authors demonstrate that the direct interaction of these inhibitors to ERK5 kinase domain induces conformational changes that promote ERK5 nuclear translocation and transcriptional activities.
