LepB inactivates Rab1, a key regulator of the secretory vesicular trafficking machinery, by acting as a GTPase-activating protein. LepB is also an antagonist of DrrA, which promotes Rab1. LepB acts by an atypical RabGAP mechanism that is reminiscent of classical GAPs. This is the C-terminal subdomain of the GAP domain and consists of an unusual fold [1].
