p38α/SAPK2a belongs to the family of mitogen-activated protein kinases (MAPK). Mitogen-activated protein (MAP) kinases comprise a family of ubiquitous proline-directed, proteinserine/ threonine kinases, which participate in signal transduction pathways that control intracellular events including acute responses to hormones and major developmental changes in organisms. p38α/SAPK2a was discovered independently in three contexts. It was found as a tyrosine phosphoprotein present in extracts of cells treated with inflammatory cytokines; as the target of a pyridinyl imidazole drug that blocked production of tumor necrosis factor-α (TNFα) and as such was called cytokine-suppressive antiinflammatory drug-binding protein or CSBP; and as a reactivating kinase for MAP kinase-activated protein (MAPKAP) kinase-2. A variety of agents including cytokines, hormones, GPCRs, osmotic and heat shock, and other stresses activate p38 family members. The recombinant human p38α kinase (SAPK2a) was expressed in E. coli and purified by Ni-agarose chromatography. The active form was produced by phosphorylation of the purified p38a with MKK6. It is suitable for labeling p38a kinase substrates.
