Anti-phospho-MEK1, (S218/222), MEK2, (S222/226) (Dual Specificity Mitogen-activated Protein Kinase

MEK1 and MEK2 are integral components of the MAP kinase cascade that regulates cell growth and differentiation and this pathway also plays a key role in synaptic plasticity in brain. Activation of MEK1/2 occurs via phosphorylation of two serine residues (Ser218 and Ser222). Activated MEK1/2 then acts as a dual specificity kinase phosphorylating both a threonine and a tyrosine residue on ERK. This phosphorylation of ERK by MEK1/2 is a critical step in the MAP kinase cascade. Applications: Suitable for use in Western Blot. Other applications not tested.
