Chemi-Verse™ MEK1 Kinase Assay Kit
The Chemi-Verse™ MEK1 Kinase Assay Kit is a luminescent assay designed to measure MEK1 (dual specificity mitogen-activated protein kinase kinase 1) kinase activity for screening and profiling applications using ADP-Glo™ as a detection reagent. The assay kit comes in a convenient 96-well format, with enough purified recombinant MEK1 kinase, kinase substrate, ATP, and kinase assay buffer for 100 enzyme reactions.
- ADP-Glo™ Kinase Assay (Promega #V6930)
- DTT (Dithiothreitol), 1M, optional
- Microplate reader capable of reading luminescence
- Adjustable micropipettor and sterile tips
- 30°C incubator
MEK1, also known as dual specificity mitogen-activated protein kinase kinase 1 or MAP2K1, is part of dual-specificity protein kinase family. MEK1 activates ERKs (extracellular signal-regulated kinases or MAPs) in response to several extra- and intracellular signals, and it is thus involved in cell proliferation and differentiation via regulation of transcription. MEK1 can be seen as the gatekeeper of ERK1/2 activity, offering a unique opportunity for inhibitors to act on all the downstream members of the ERK pathway. MEK1/2 has a very unique hydrophobic pocket which allows for binding of non-ATP competitive allosteric inhibitors, disturbing the formation of RAF (proto-oncogene serine/threonine-protein kinase)-MEK complexes or MEK phosphorylation. Inhibitors for MEK1 are currently used in combination with B-RAF1 inhibitors for the treatment of B-RAF-mutant melanoma. Further studies are required to design inhibitors that act mainly in abnormal tissues, as MEK1 is also expressed in normal cells, and to bypass resistance mechanisms.
