Fig. 7. Proposed model of AK2 function as a BRAF locker in the RAS-BRAF signaling.

A Under resting condition with high AMP level, AK2 senses AMP and forms a protein complex with BRAF to inhibit the BRAF activity. B Upon mitogen stimulation and RAS activation, AK2 is released from BRAF, leading to activation of BRAF.
