The extracellular signal-regulated kinase 5 (ERK5), also known as MAPK7 or big mitogen-activated protein kinase 1 (BMK1), is a member of the MAP kinase subfamily (1). ERK5 differs considerably from other MAPKs; it contains an unusually long carboxyl-terminal tail which might contribute to the regulation of its activity and/or localization. In response to extracellular signals, ERK5 translocates to the nucleus, where it regulates gene expression by phosphorylating, and activating different transcription factors (2). ERK5 also differs from other MAPKs in possessing a potent transcriptional activation domain which mediates protein-protein interactions with the myocyte enhancer factor 2 (MEF2) transcription factors (3). ERK5 is specifically activated by MAPK kinase 5 (MAP2K5/MEK5) and plays an important role in mammary epithelial proliferation, endothelial cell survival and normal embryonic development (4-5).
