| Target Information | |
|---|---|
| Target Name | MEK1/2 |
| Gene Abbr. | MAP2K1 |
| Gene ID | 5604 |
| Full Name | mitogen-activated protein kinase kinase 1 |
| Alias | CFC3, MAPKK1, MEK1, MEL, MKK1 |
| Introduction | MEK1 and MEK2, also called MAPK or Erk kinases, are dual-specificity protein kinases that function in a mitogen activated protein kinase cascade controlling cell growth and differentiation. Activation of MEK1 and MEK2 occurs through phosphorylation of two serine residues at positions 217 and 221, located in the activation loop of subdomain VIII, by Raf-like molecules. MEK1/2 is activated by a wide variety of growth factors and cytokines and also by membrane depolarization and calcium influx. Constitutively active forms of MEK1/2 are sufficient for the transformation of NIH/3T3 cells or the differentiation of PC-12 cells. MEK activates p44 and p42 MAP kinase by phosphorylating both threonine and tyrosine residues at sites located within the activation loop of kinase subdomain VIII.CST's Phospho- MEK1/2 (Ser217/221) Antibody selectively recognizes active MEK, i.e., only when phosphorylated at Ser217/221, and hence is an excellent marker of MEK1/2 activity. |

| Immunogen | Synthetic phosphopeptide corresponding to residues around Ser217/221 of human MEK1/2. |
| Source/Purification | Antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues around Ser217/221 of human MEK1/2. Antibodies are purified by protein A and peptide affinity chromatography. |
| Usage | |
|---|---|
| Application | WB, IP |
| Dilutions | Western Blot (1:1000); Immunoprecipitation (1:50) |
| MW(KDa) | 45 |
| Reactivity | Human, Mouse, Rat, Monkey, S. cerevisiae |
| Sensitivity | Endogenous |
| Specificity | It detects endogenous levels of MEK1/2 only when activated by phosphorylation at Ser217/221. This antibody does not cross-react with related kinases including activated SEK (MKK4), MKK3 or MKK6. It will also react with MEK1/2 singly phosphorylated at Ser217 and singly phosphorylated at Ser221. |
