Endosome-to-cell surface recycling is mediated by retromer and Snx27. In this issue, Mao et al. (2021. J. Cell Biol.https://doi.org/10.1083/jcb.202010048) detail how endosomal protein sorting responds to external stimuli and reveal that phosphorylation of Snx27 regulates its cargo-binding function resulting in reduced endosome-to-cell surface recycling.
