Abstract excerpt
Raf-1 is a serine/threonine protein kinase that plays a critical role in mitogenic signal transduction. Raf-1 activation requires 14-3-3 binding to Raf-1 as an essential step. This binding is regulated through phosphorylation of Ser259 and Ser621 of Raf-1, each constituting part of the consensus motif for the binding of Raf-1 to 14-3-3. However, Raf-1 kinase kinase(s) that phosphorylates these sites remains...
