T286-p - MEK1 (mouse)
Orthologous residues
MEK1 (human): T286‑p, MEK1 iso2 (human): T260‑p, MEK1 (mouse): T286‑p, MEK1 (rat): T286‑p, MEK1 (rabbit): T286‑p
 Enzymes shown to modify site in vitro
Type Enzyme
KINASE CDK5 (mouse)
 Comments:  Inactive MEK1 was not phosphorylated by CDK5/p25, but Raf-phosphorylated MEK1 was good substrate of CDK5/p25.
Upstream Regulation
 Potential in vivo enzymes for site: 
Type Enzyme Evidence Notes
KINASE CDK5 (mouse) genetic transfer of wild-type enzyme, genetic transfer of dominant-negative enzyme, genetic knockout/knockin of upstream enzyme, pharmacological activator of upstream enzyme
Downstream Regulation
 Effect of modification (function):  enzymatic activity, inhibited
