Specific subunit of the TRAPP II complex, a highly conserved vesicle tethering complex that functions in the late Golgi as a guanine nucleotide exchange factor (GEF) for the Golgi YPT1 GTPase. TRS130 plays a role in the YPT GEF activity of TRAPP II in concert with the two other TRAPP II-specific subunits TRS65 and TRS120. Required for both the cytoplasm-to-vacuole targeting (Cvt) pathway and starvation-induced autophagy through its role in ATG8 and ATG9 trafficking. Part of the multisubunit TRAPP (transport protein particle) II complex composed of BET3, BET5, TRS20, TRS23, TRS31, TRS33, TRS65, TRS120 and TRS130. Interacts with YPT31 and YPT32. Present with 432 molecules/cell in log phase SD medium. Belongs to the TMEM1 family.
