Mitogen-activated protein kinase kinase 1 (MEK1 or MAPKK1, 43.5kD) is a member of a family of tyrosine/threonine protein kinases that activate the ERK1&2/MAPK enzymes by phosphorylating both residues within the threonine-glutamic acid-tyrosine (TEY) motif in the activation loop.
MEK1&2 are also activated by dual-phosphorylation, which occurs on serines 218 and 222, in the activation loop of the MEKs.
Threonine 292 of MEK1 is phosphorylated by ERK1&2, which serves as a negative feedback loop by suppressing activation of MEK1.
