CC -!- FUNCTION: Phospholipid scramblase involved in autophagy by mediating
CC autophagosomal membrane expansion. Cycles between the preautophagosomal
CC structure/phagophore assembly site (PAS) and the cytoplasmic vesicle
CC pool and supplies membrane for the growing autophagosome. Lipid
CC scramblase activity plays a key role in preautophagosomal
CC structure/phagophore assembly by distributing the phospholipids that
CC arrive through ATG2 (ATG2A or ATG2B) from the cytoplasmic to the
CC luminal leaflet of the bilayer, thereby driving autophagosomal membrane
CC expansion. Also required to supply phosphatidylinositol 4-phosphate to
CC the autophagosome initiation site by recruiting the
CC phosphatidylinositol 4-kinase beta (PI4KB) in a process dependent on
CC ARFIP2, but not ARFIP1 (By similarity). In addition to autophagy, also
CC plays a role in necrotic cell death (By similarity).

CC -!- SUBUNIT: Homotrimer; forms a homotrimer with a central pore that forms
CC a path between the two membrane leaflets. Interacts (via cytoplasmic
CC its C-terminus) with ATG2A. Interacts with SUPT20H. Interacts (via the
CC tyrosine-based sorting signal motif) with AP4M1; promoting association
CC with the AP-4 complex. Interacts with ARFIP1 and ARFIP2. Interacts with
CC PI4K2A and PI4KB. Interacts with ATG4A; the interaction is direct and
CC promotes ATG9A trafficking. {ECO:0000250|UniProtKB:Q7Z3C6}.

CC {ECO:0000250|UniProtKB:Q7Z3C6}; Multi-pass membrane protein
CC {ECO:0000255}. Note=Mainly localizes to the trans-Golgi network (TGN)
CC and the endosomal system; cycles between them though vesicle
CC trafficking. Export from the TGN to promote formation of autophagosomes
CC is mediated by the AP-4 complex. Under amino acid starvation or
CC rapamycin treatment, redistributes to preautophagosomal
CC structure/phagophore assembly site (PAS). The starvation-induced
CC redistribution depends on ULK1, ATG13, as well as SH3GLB1. Upon
CC autophagy induction, a small portion transiently localizes to the
CC autophagic membranes. Recruited to damaged mitochondria during
CC mitophagy in a RIMOC1-dependent manner. {ECO:0000250|UniProtKB:Q7Z3C6}.
CC -!- DOMAIN: Forms a homotrimer with a solvated central pore, which is
CC connected laterally to the cytosol through the cavity within each
CC protomer. Acts as a lipid scramblase that uses its central pore to
CC function: the central pore opens laterally to accommodate lipid
CC headgroups, thereby enabling lipid flipping and redistribution of
CC lipids added to the outer leaflet of ATG9A-containing vesicles, thereby
CC enabling growth into autophagosomes. {ECO:0000250|UniProtKB:Q7Z3C6}.
CC -!- DOMAIN: The tyrosine-based sorting signal motif, also named YXX-psi
CC motif, promotes interaction with the AP-4 complex.
CC {ECO:0000250|UniProtKB:Q7Z3C6}.
CC -!- SIMILARITY: Belongs to the ATG9 family. {ECO:0000305}.
