While several in vitro screens revealed that SidM binds up to 9 Rab GTPases and LidA binds 25 Rab GTPases, we have shown that intracellular SidM specifically binds Rab1A, 1B, 6, and 10 during infection while LidA binds Rab1A, 1B, 3D, 6, 8A, 10, 14, and 18. The gene discussed is RAB6A; the disease is infection.
