VUBI1 is a мощный activator of SOS1 which modulates the KRAS pathway, binds directly to SOS1 (Kd=44 nM); VUBI1 increase nucleotide exchange on RAS in vitro at sub-micromolar concentration, rapidly enhances клеточный RAS-GTP levels, and invoke biphasic signaling changes in phosphorylation of ERK 1/2 (Hela pERK ICW EC50=5.9 uM).
