CC   -!- FUNCTION: Plays a role in constitutive metalloproteinase (MMP)
CC       secretion from the trans Golgi network. May have important functions
CC       during vesicle biogenesis at certain cargo subdomains, which could be
CC       predominantly utilized by secreted MMPs, such as MMP7 and MMP2. Also
CC       involved in autophagy by regulating the starvation-dependent
CC       trafficking of ATG9A vesicles which deliver the phosphatidylinositol 4-
CC       kinase beta (PI4KB) to the autophagosome initiation site. Involved in
CC       phagophore growth during mitophagy by regulating ATG9A trafficking to
CC       mitochondria. In addition, plays a role in NF-kappa-B inhibition by
CC       interacting with IKBKB and IKBKG. {ECO:0000250|UniProtKB:P53365}.
CC   -!- SUBUNIT: Forms homodimers or heterodimers with ARFIP1. Interacts with
CC       RAC1. Specifically binds to GTP-bound ARF1 and ARF6, but binds to
CC       RAC1.GTP and RAC1.GDP with similar affinities. Interacts with ARL1.
CC       Interacts (via N-terminus) with IKBKB and IKBKG; these interactions
CC       inhibit activation of NF-kappa-B. {ECO:0000250|UniProtKB:P53365}.
CC   -!- SUBCELLULAR LOCATION: Golgi apparatus {ECO:0000250|UniProtKB:P53365}.
CC       Golgi apparatus, trans-Golgi network membrane
CC       {ECO:0000250|UniProtKB:P53365}.
