Under non stimulatory conditions a serine of CR2 domain and another near the C-terminus are phosphorylated and are bound to 14-3-3 domain. To activate RAF Kinases, RAS-GTP has to interact with the RDB Domain. This is necessary but not enough to activate the RAF Kinase.

One characteristic that distinguish B-RAF from A or C-RAF is the presence of Asp448 and Asp449 on the N-terminal region, which bear negative charges. Phosphorylation of <scene name='Sandbox_Reserved_707/Psite_of_activation_segment/1'>Thr599</scene> and Ser602 in the activation segment is essential for B-RAF activation. Another residue is crucial for the activation of this enzyme as well: the phosphoserine 579<ref>PMID:16093354</ref> of the catalytic loop. That’s why the basal activity of B-RAF is greater than A or C-RAF.<br />
