A general role for GGA adaptors in the modulation of AP-1-dependent trafficking

Alexander Stockhammer, Antonia Klemt, Aline Dominique Daberkow…·Francesca Bottanelli

This study investigates the role of GGAs in AP-1-dependent trafficking using CRISPR-Cas9 and live-cell imaging, finding GGAs modulate bi-directional trafficking by preventing AP-1 cargo retrieval.

ARF1 compartments direct cargo flow via maturation into recycling endosomes

Alexander Stockhammer, Petia Adarska, Vini Natalia…·Francesca Bottanelli

The paper identifies two functionally distinct ARF1 compartments involved in post-Golgi sorting and endocytic recycling, challenging the classical vesicle shuttling model.
