Involved in retrograde transport from early and late endosomes to late Golgi. Links the Golgi-associated retrograde protein (GARP) complex to the t-SNARE TLG1, leading to the fusion between the endosomal vesicles with the late Golgi. May also be indirectly involved in apical bud growth. Component of the Golgi-associated retrograde protein (GARP) complex, also called VPS fifty three (VFT) complex, composed of VPS51, VPS52, VPS53 and VPS54. Interacts with the t-SNARE TLG1. Present with 319 molecules/cell in log phase SD medium. Belongs to the VPS51 family.
