Anti-Arfaptin 1

function:Putative target protein of ADP-ribosylation factor.,similarity:Contains 1 AH domain.,subunit:Interacts with non-myristoylated GTP-bound ARF3, but not to GDP-bound ARF3, and also to ARF1. Binds with lower affinity to ARF5 and with very little affinity to ARF6.,tissue specificity:Ubiquitously expressed. Higher levels in liver, pancreas, placenta, skeletal muscle and heart., Protein function: Plays a role in controlling biogenesis of secretory granules at the trans-Golgi network (PubMed:22981988). Mechanistically, binds ARF-GTP at the neck of a growing secretory granule precursor and forms a protective scaffold (PubMed:9038142, PubMed:22981988). Once the granule precursor has been completely loaded, active PRKD1 phosphorylates ARFIP1 and releases it from ARFs (PubMed:22981988). In turn, ARFs induce fission (PubMed:22981988). Through this mechanism, ensures proper secretory granule formation at the Golgi of pancreatic beta cells (PubMed:22981988).
