The critical event in KRAS signaling and oncogenic transformation is activation of the RAF–MEK–MAPK cascade. This requires assembly of a multiprotein–lipid complex on the plasma membrane. In a tour de force of modeling, Mysore et al. now provide the first glimpse of what this structure may actually look like.
