== Function ==
[https://www.uniprot.org/uniprot/YPT1_YEAST YPT1_YEAST] Involved in the trafficking of secretory vesicles from the endoplasmic reticulum (ER) to the Golgi. Regulates correct targeting and tethering of vesicles to target membranes by catalyzing the selective recruitment of proteins required for tethering and fusion onto membranes. Vesicular transport depends on shuttling of YPT1 between membrane and cytosol by GDI1, probably by recycling it to its membrane of origin after a vesicle fusion event. Required for sorting and transport of proteins from the ER through the Golgi compartment. Also involved in the recycling of membrane proteins.<ref>PMID:3286011</ref> [:]<ref>PMID:11879636</ref> <ref>PMID:12189143</ref> <ref>PMID:12802060</ref> <ref>PMID:15082776</ref>
