1 Translocation of the fused wildtype Rac1 effector permits its activation by GEFs (guanine nucleotide exchange factors) and consequent actin polymerization and lamellipodia formation, unlike in existing single-chain systems that operate by allosteric photo-switching of constitutively active Rac1 or the heterodimerization-based (i.e. two-component) membrane recruitment of a Rac1-activating GEF.
