Supplied as a liquid in PBS, 0.05% BSA, 0.05% sodium azide.

Synthetic peptide corresponding to aa200-250, containing phosphorylated serine residues at positions 218 and 222, of human MEK1.

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.
