Involved in retrograde transport from early and late endosomes to late Golgi by linking the vesicle through the t-SNARE TGL1 to the Golgi, leading to the membrane fusion between late Golgi and endosomal vesicles. May also be involved in the actin cytoskeleton organization. Component of the Golgi-associated retrograde protein (GARP) complex, also called VFT (VPS fifty-three) complex, composed of VPS51, VPS52, VPS53 and VPS54. Interacts also with TLG1 and YPT6. Present with 3130 molecules/cell in log phase SD medium. Belongs to the VPS52 family.
