Anti-SAPK1, JNK (Stress Activated Protein Kinase, Jun Kinase)

Stress-activated protein (SAP) kinases are proline-directed, serine/threonine-specific kinases that require phosphorylation on tyrosine for phosphotransferase activity.SAP Kinase was originally shown to phosphorylate microtubule-associated protein-2, but c-Jun appears to be an important physiological target of this kinase. Consequently SAPK has also been called Jun Kinase. Phosphorylation of Ser-63 and Ser-73 of c-Jun by SAP kinases promotes activation of the transcription factor AP-1. cDNA cloning studies with rat and human libraries have shown that there are several isoforms of the SAP Kinase family. Many stimuli activate SAP Kinase, including heat shock, 7 hyperosmotic shock, UV irradiation, exposure to protein synthesis inhibitors such as cycloheximide and anisomycin, and treatment with proinflammatory cytokines such as tumor necrosis factor-a.
