Domain (CC)
Switch 1, switch 2 and the interswitch regions are characteristic of Rab GTPases and mediate the interactions with Rab downstream effectors. The switch regions undergo conformational changes upon nucleotide binding which drive interaction with specific sets of effector proteins, with most effectors only binding to GTP-bound Rab.
