RUSHing back: Kinetic analysis of adaptor protein complex-1 (AP-1)–mediated retrograde traffic

Abstract

Numerous biomedically important cargoes depend on adaptor protein complex-1 (AP-1) for their localization. However, controversy surrounds whether AP-1 mediates traffic from or to the Golgi. Robinson et al. (https://www.doi.org/10.1083/jcb.202310071) present compelling evidence that AP-1 mediates recycling to the Golgi.
