  • Cryo-EM structures show how BRAF, MEK, and a 14-3-3 dimer or organized in autoinhibited and active states
  • Binding of ATP in the active site of RAF is crucial for maintaining auto inhibition, RAF inhibitors that displace it cause activation
  • RAS can engage autoinhibited RAF complexes without disrupting them
  • Stabilizing autoinhibited RAF
  • Complexes may be an attractive therapeutic alternative to blocking binding of active Ras or inhibiting active Raf
