Plays a role in controlling biogenesis of secretory granules at the trans-Golgi network. Mechanisitically, binds ARF-GTP at the neck of a growing secretory granule precursor and forms a protective scaffold. Once the granule precursor has been completely loaded, active PRKD1 phosphorylates ARFIP1 and releases it from ARFs. In turn, ARFs induce fission. Through this mechanism, ensures proper secretory granule formation at the Golgi of pancreatic beta cells. Forms homodimers or heterodimers with ARFIP2. Interacts with non-myristoylated GTP-bound ARF3, but not to GDP-bound ARF3. Interacts with ARF1. Binds with lower affinity to ARF5 and with very little affinity to ARF6. Interacts with ARL1. Interacts with ATG9A.
