WebAbstact. Raf-1 kinase inhibitor protein (RKIP) has been reported to negatively regulate signal kinases of major survival pathways. RKIP activity is modulated in part by phosphorylation on Serine 153 by protein kinase C, which leads to dissociation of RKIP from Raf-1. Web7. A signaling kinase (kinase A) in a signaling pathway phosphorylates another kinase called kinase B, activating it. Kinase B in turn phosphorylates kinase C (another kinase in the pathway), activating it. Kinase B also phosphorylates phosphatase B, which has kinase B as its substrate. This is an example of: Answer: a. Signal amplification. 8.
