MEK 1 and MEK 2 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 MEK 1/2 occurs via phosphorylation of two serine residues (Ser218 and Ser222). Activated MEK 1/2 then acts as a dual specificity kinase phosphorylating both a threonine and a tyrosine residue on ERK. This phosphorylation of ERK by MEK 1/2 is a critical step in the MAP kinase cascade.

保存建议
For long term storage –80˚C is recommended, but shorter term storage at –20˚C is also acceptable as aliquots may be taken without freeze/thawing due to the presence of 50% glycerol. Stable for one year.
