1 The results reveal that Rac1 residues of both the switch I and switch II regions are involved in GEF docking and GEF-mediated nucleotide disruption, because mutation of Asp(38), Asn(39), Gln(61), Tyr(64), or Arg(66)/Leu(67) into Ala results in the loss of GEF binding, whereas mutation at Tyr(32), Asp(65), or Leu(70)/Ser(71) leads to the loss of GEF catalysis while retaining the binding capability.
