p38 beta: Products

The p38 mitogen-activated protein kinases (p38 MAP kinases) are a family of four related Ser/Thr kinases responsive to pro-inflammatory cytokines and environmental stresses, including ionizing radiation, oxidative stress, and osmotic shock. Each family member, p38 alpha, p38 beta, p38 delta, and p38 gamma, is activated by dual Thr and Tyr phosphorylation within a Thr-Gly-Tyr motif residing in the kinase activation loop. For p38 beta, also known as p38-2, stress-activated protein kinase 2B (SAPK2B), and MAPK11, this dual phosphorylation occurs at Thr180/Tyr182.
