Anti-MAP Kinase, p38 (MAPK, Erk2, Extracellular Signal Regulated Kinase, RK, CSBP, Mitogen Activated

p38 MAP kinase (MAPK) is also called RK (3) or CSBP (2). It is the mammalian homologue of the yeast HOG kinase. It 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. 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 threonine 180 and tyrosine 182. 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).
