Plays a role in the regulation of starvation-induced autophagosome formation . Together with the TRAPPIII complex, regulates a constitutive trafficking step from peripheral recycling endosomes to the early Golgi, maintaining the cycling pool of ATG9 required for initiation of autophagy.
Subcellular locations: Golgi apparatus, Cis-Golgi network, Golgi apparatus, Trans-Golgi network
After amino acid starvation, Golgi apparatus-associated protein levels increase compared with fed conditions. May be cycling between the Golgi apparatus and an endosomal pool, redistributing to the Golgi apparatus upon starvation.
