  • 功能：
    The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes. Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different set of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion. YPT1 regulates the trafficking of secretory vesicles from the endoplasmic reticulum (ER) to the Golgi. 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. Plays a role in the initial events of the autophagic vacuole development which take place at specialized regions of the endoplasmic reticulum. Also involved in the recycling of membrane proteins.

    2. Since these there proteinases belong to the CPY pathway, YPT1 is even believed to up-regulate this trafficking pathway in yeast cells. Future studies, however, should be carried out to discover the mechanisms that allow YPT1 to recruit these proteins into yeast vacuoles PMID: 26895320
    3. that changes in Ypt1 and Ypt31 activity affect Golgi cisternal progression, early-to-transitional and transitional-to-late, respectively PMID: 26906739
    4. Ypt1 binds and activates Hrr25 to spatially regulate its kinase activity. PMID: 26195667
    5. Finally, three sequential steps of this pathway are delineated: Atg9-dependent exit from the ER en route to autophagy, Ypt1- and core Atgs-mediated pre-autophagsomal-structure organization, and Ypt51-mediated delivery of APs to the vacuole PMID: 26181331

    7. These findings establish a role for an autophagy-specific Ypt1 module in the regulation of ER-phagy. Moreover, because Ypt1 is a known key regulator of ER-to-Golgi transport, these findings establish a second role for Ypt1 at the ER PMID: 23924895
    8. Findings show that Ypt1/Rab1 infindings show that Ypt1/Rab1 interacts with Atg1/Ulk1 in yeast and mammalian cells. PMID: 23716696
    9. Trs85 and Ypt1 are localized to the preautophagosomal structure in an Atg9-dependent manner. PMID: 23129774
    10. Our findings establish that Ypt1 contributes to regulation of UPR signaling dynamics by promoting the decay of HAC1 RNA, suggesting a potential regulatory mechanism for linking vesicle trafficking to the UPR and ER homeostasis PMID: 22844259
    11. Ypt1 and Atg11 colocalize with Trs85, a Ypt1 activator subunit, and together they regulate selective autophagy. PMID: 22509044
    12. Ypt1 is essential for autophagy. PMID: 20375281
    13. alpha-Synuclein expression blocks ER-to-Golgi vesicular trafficking; in a genomewide screen, the largest class of toxicity modifiers were proteins functioning at this step including Ypt1p which associated with cytoplasmic alphaSyn inclusions PMID: 16794039
    14. These results show that Trs65 plays a role in the Ypt guanine nucleotide exchanger activity of TRAPP II in concert with the two other TRAPP II-specific subunits. PMID: 17475775
    15. These results confirm the link between translation and vesicular trafficking and reinforce the implication of eIF5A in protein synthesis. PMID: 18568365
    16. Study presents the structure of a heteropentameric TRAPPI assembly complexed with Ypt1p & leads to proposal for mechanism for guanine nucleotide exchange in which each subunit in the TRAPPI subassembly contributes to the activity of this multimer. PMID: 18585354
    17. identify the kinetic and thermodynamic bases by which TRAPP catalyzes nucleotide exchange from Ypt1p PMID: 19361519
    18. Data show that Gyp1p, a GAP for Ypt1p, specifically interacts with Ypt32p, and that this interaction is important for the localization and stability of Gyp1p. PMID: 19666511
