Assessment of Rab11-FIP2 interacting proteins in vitro
Abstract:
Members of the Rab family of small GTPases are involved in multiple trafficking events in both endocytotic and biosynthetic pathways. To understand more fully the regulation of these events, a concerted effort is underway to ascertain the binding partners and regulators of Rabs. Here, we describe methods to assess binding of Rab11a with Rab11-FIP2 and other Rab11-FIPs utilizing a modified far-Western approach. We then broaden this application to assess binding of Rab11-FIP2 with myosin Vb and homodimerization of Rab11-FIP2.

Rab Proteins
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...
