ARF-1 coordinates cargo sorting at FERARI endosomal recycling hubs.

ARF-1 GTPase is essential for cargo loading at FERARI-dependent endosomal recycling sites, regulating vesicle formation in endosomal pathways.

• Why it matters: Understanding cargo sorting at endosomes is crucial for insights into cellular organization and communication, yet the regulatory mechanisms remain incompletely understood.
• What they did: The study identified ARF-1 as a key regulator of cargo capture at FERARI-dependent endosomal kiss-and-run sites, demonstrating that cycling between active and inactive states is necessary for efficient recycling.
• The result: Findings suggest that ARF-1 activity controls the timing of cargo association with adaptor proteins, revealing a new layer of regulation in endosomal recycling and the interaction between ARF and Rab GTPases.
