Summation

Raf is a downstream effector of ras. Raf is activated upon phosphorylation at S338, oligomerization and membrane localization. Membrane localization is facilitated by ras. Interaction of ras with raf is a necessary step but not sufficient for raf activation. Other unknown protein partner interactions are required for raf activation. Raf further activates MAP kinase.
