| Storage and Stability: | Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws. |
| Target description: | Dual specificity mitogen-activated protein kinase kinase 1 (UniProt: Q02750; also known as EC:2.7.12.2, MAP kinase kinase 1, MAPKK 1, MKK1, ERK activator kinase 1, MAPK/ERK kinase 1, MEK 1) is encoded by the MEK1 (also known as MAP2K1, PRKMK1) gene (Gene ID: 5604) in human. MEK1 is a dual specificity protein kinase that acts as an essential component of the MAP kinase signal transduction pathway. It is widely expressed, but very low levels are detected in the brain tissue. Activation of MEK1 involves binding of extracellular ligands such as growth factors and cytokines to their membrane receptors that activates RAS and then RAF. Once activated, GTP-bound RAS can drive the formation of high-activity homodimers or heterodimers of the RAF protein kinases (ARAF, BRAF or CRAF) that can directly phosphorylate and activate MEK1 and MEK2. Their activation occurs through phosphorylation of Ser 218 and Ser 222 residues. MEK1/2 in turn can activate ERK1 and ERK2 by phosphorylating them at conserved threonine and tyrosine residues in the Thr-Glu-Tyr motif in their activation loop. MEK1 is reported to be the target of negative feed-back regulation by its substrate kinases ERK2, which can phosphorylate MEK1 on Thr 292 and facilitate dephosphorylation of the activating residues Ser 218 and Ser 222. Although MEK1/2 mutations are relatively rare in cancer, expression of constitutively active forms of their mutants are reported to be sufficient to induce oncogenic transformation of normal cells. This ZooMAbZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
