EARP is a multisubunit tethering complex involved in endocytic recycling.

ABSTRACT: Recycling of endocytic receptors to the cell surface involves passage through a series of membrane-bound compartments by mechanisms that are poorly understood. In particular, it is unknown if endocytic recycling requires the function of multisubunit tethering complexes, as is the case for other intracellular trafficking pathways. Herein we describe a tethering complex named endosome-associated recycling protein (EARP) that is structurally related to the previously described Golgi-associated retrograde protein (GARP) complex. The two complexes share the Ang2, Vps52 and Vps53 subunits, but EARP contains an uncharacterized protein, syndetin, in place of the Vps54 subunit of GARP. This change determines differential localization of EARP to recycling endosomes and GARP to the Golgi complex. EAR
