MEKK2 Is Required for T-cell Receptor Signals in JNK Activation and Interleukin-2 Gene Expression

Abstract excerpt

The c-Jun N-terminal kinases (JNKs) are members of the mitogen-activated protein kinase (MAPK) gene family and are essential for cell proliferation, differentiation, and apoptosis. Previously we found that activation of JNK in T-cells required costimulation of both T-cell receptor and auxiliary receptors such as CD28. In this study, we cloned a full-length human MEK kinase (MEKK) 2 cDNA from Jurkat T-cells and...
