Dual specificity mitogen-activated protein kinases (MEK) are members of the dual specificity protein kinase family, which act upstream from the classical MAP kinases through phosphorylation and thus activation of ERK1 and 2 in response to a wide variety of extra and intracellular signals. While the functions of MEK1 and MEK2 are very similar, these kinases differ significantly in the way they are regulated. For example, serum addition can specifically induce MEK1 activity in CHO cells. By contrast, MEK2 appears to be the functionally predominant isoform in formyl-methionyl-leucyl-phenylalanine treated neutrophils. Here we show MEK1 activation in MCF10A cells treated with EGF.
