"Inactive Raf-1 is associated in the cytoplasm with 14-3-3. 14-3-3 binds to Raf-1 via the Ser259 phosphorylation site (S1). This interaction stabilises the inactive conformation of Raf-1 in which the Ras-binding Cysteine-rich domain (CRD) is obscured. The Raf-1 molecule contains an additional p21ras-binding domain (RBD), a second serine phosphorylation site at S621 (S2) and two tyrosine phosphorylation sites (at 340, Y1 and 341, Y2)."^^ . . . . . .
