Abstract excerpt
Raf kinase inhibitory protein (RKIP; also known as phosphatidylethanolamine-binding protein or PEBP) is a modulator of the Raf/MAPK signaling cascade and a suppressor of metastatic cancer. Here, we show that RKIP inhibits MAPK by regulating Raf-1 activation; specifically, RKIP acts subsequent to Raf-1 membrane recruitment, prevents association of Raf-1 and p21-activated kinase (PAK), and blocks phosphorylation of...
