Question

Complementary Rab proteins on transport vesicles and target membranes bind to one another to allow transport vesicles to dock selectively at their appropriate target membranes.
A. True
B. False

Answer 1

Answer:

The correct answer will be- False

Explanation:

Rab proteins belong to G-protein Ras superfamily of proteins which are involved in the process of protein trafficking or transport.

The protein trafficking between ER and Golgi apparatus is mediated by the formation of vesicles which are coated with important molecules like clathrin and Rab proteins.

The presence of Rab proteins on vesicle help the vesicle to bind or docking to the target cell due to the interaction of the Rab proteins to the complementary effectors. The specific binding of the Rab proteins to Rab effectors allows the activation of Rab proteins.

Since Rab proteins bind the Rab effector instead of Rab proteins therefore false is the correct answer.
