Biological Information

Background Information:

MAPK1 (mitogen-activated protein kinase 1, ERK2 or extracellular signal –regulated protein kinase) is one of the isoforms of MAP kinase. This serine/threonine kinase is activated by dual phosphorylation on tyrosine and threonine residues (Tyr-185 and Thr-183). Phosphorylation of both residues by the upstream activator MEK (mitogen-activated protein kinase kinase, MAP2K) is essential not only for ERK2 activation, but also for translocation of the ERK2 to the nucleus. Following this activation, ERK2 phosphorylates a large number of regulatory proteins and this directly controls key cellular processes such as transcription, translation and cytoskeletal rearrangement. An inhibitor assay may be of benefit for the treatment of cancer, diabetes, neurodegenerative disorders or asthma.

Testing Information

Procedure Summary:

Human recombinant protein kinase ERK2 expressed in E. coli is used. Test compound and/or vehicle is preincubated with 1 U/ml enzyme‡ in MOPS buffer pH 7.2 for 15 minutes at 37°C. The reaction is initiated by addition of 50 μg/ml myelin basic protein (MBP), 10 μM ATP and 0.25 μCi [γ32P]ATP for another 30 minute incubation period and terminated by cooling on ice. An aliquot is removed and counted to determine the amount of [32P]MBP formed. Compounds are screened at 10 μM.
