Acts as a guanine-nucleotide exchange factor (GEF). Promotes guanine-nucleotide exchange on ARF1, ARF3 and ARF6. Activates ARF factors through replacement of GDP with GTP (By similarity). The cell membrane form, in association with ARL4 proteins, recruits ARF6 to the plasma membrane (PubMed:17398095). Involved in neurite growth (By similarity).By similarity1 Publication

Interacts with ARL4D; the interaction is direct (PubMed:17398095). Directly interacts with CCDC120 through the coiled coil domain; this interaction stabilizes CCDC120, possibly by preventing its ubiquitination, and is required for neurite growth in neuroblastoma cells (PubMed:25326380).

Interacts with ARF1 (PubMed:14654833).

Interacts with FRMD4A (By similarity).

Interacts (via N-terminal domain) with INAVA (via N-terminal domain) (PubMed:29420262).
