A Novel Specific Role for IκB Kinase Complex-associated Protein in Cytosolic Stress Signaling

Abstract excerpt

We demonstrate here a novel role for the I kappa B kinase complex-associated protein (IKAP) in the regulation of activation of the mammalian stress response via the c-Jun N-terminal kinase (JNK)-signaling pathway. We cloned IKAP as a JNK-associating protein using the Ras recruitment yeast two-hybrid system. IKAP efficiently and specifically enhanced JNK activation induced by ectopic expression of MEKK1 and ASK1,...
