Soluble Rab is GDP bound. Put the following in the correct order of how Rab regulates vesicle targeting. Below is a sequence of events. Place them in the order they should occur, number 1 being the first item. Select the step number from the drop down next to each item. Items to order:
1. Rab is recognized by an effector on the target compartment.
2. GTP is hydrolyzed to GDP
3. The vesicle forms, buds from the donor, and is uncoated.
4. Rab disassociates from the membrane.
5. GDP is released and GTP binds to Rab
6. The vesicle fuses with the donor compartment
7. Rab becomes anchored to the membrane Rab is recognized by an effector on the target compartment.
