Raf kinase inhibitory protein (RKIP, PEBP) is a modulator of the Raf/MAPK signaling cascade and a suppressor of metastatic cancer. RKIP inhibits MAPK by preventing association of Raf-1 and p21-activated kinase (PAK), and blocking phosphorylation of the Raf-1 kinase domain by PAK and Src kinases. After G protein receptor stimulation, RKIP can dissociate Raf-1 and associate with GRK2, thereby blocking GRK2 activity. This switch is triggered by protein kinase C (PKC)-dependent phosphorylation of the RKIP on Serine 153. RKIP Serine 153 phosphorylation by PKC in response to phorbol ester or epidermal growth factor causes release of RKIP from Raf-1. RKIP antagonizes the signal transduction pathways that mediate the activation of NFkB in response to stimulation with TNF-a or interleukin-1 b.
