Abstract
We previously showed that the small GTPase Rab4 regulates formation of recycling vesicles from early endosomes. To understand how Rab4 accomplishes this task, we started to identify the Rab4 effector protein network. In this chapter, we describe experiments leading to the characterization of a complex consisting of Rab4GTP, its effector Rabaptin-5alpha, and the adaptor protein complex AP-1, which regulates recycling from endosomes.
