WebArrows indicate direction of transferrin recycling. Cargo enters the cell via mainly Rab5-containing structures. Fast recycling is achieved by rapid sorting from Rab5 into Rab4-positive domains on the same endosome. Recycling slows down once transferrin enters pericentriolar membranes dominated by Rab4 and Rab11 domains.

WebRecent studies have shown that APPL1 endosomes function in the rapid recycling of a subset of GPCRs (Jean-Alphonse et al., 2014; Sposini et al., 2024) and that this recycling pathway is inhibited by a negative feedback loop driven by cAMP-dependent activation of protein kinase A. Together with our findings, these results suggest that APPL1 ...
