MAP Kinase p38 alpha (MAPK14, Mitogen-activated Protein Kinase p38 alpha, Mitogen-activated Protein Kinase 14, CSBP, Cytokine Suppressive Anti-inflammatory Drug-binding Protein, CASID-binding Protein, SAPK2A, CSBP, CSBP1, CSBP2, CSPB1, MXI2)

P38 MAP kinase (MAPK), also called RK (3) or CSBP (2), is the mammalian homologue of the yeast HOG kinase and participates in a signaling cascade controlling cellular responses to cytokines and stress (1-4). Four isoforms of p38 MAP kinase, alpha, beta, gamma and delta, have been identified so far. Like the SAPK/JNK pathway, p38 MAP kinase is activated by a variety of cellular stresses including osmotic shock, inflammatory cytokines, lipopolysaccharides (LPS), UV light and growth factors (1-5). MKK3 and SEK activate p38 MAP kinase by phosphorylation at Thr180 and Tyr182. Activated p38 MAP kinase has been shown to phosphorylate and activate MAPKAP kinase 2 (3) and to phosphorylate the transcription factors ATF-2 (5), Max (6) and MEF2 (5-8).\n\nApplications: \nSuitable for use in Western Blot, Immunoprecipitation and Immunohistochemistry.
