Secretion of Wnt proteins is mediated by the Wnt sorting receptor Wls, which transports Wnt from the Golgi to the cell surface for release. To maintain efficient Wnt secretion, Wls is recycled back to the trans-Golgi network (TGN) through a retromer dependent endosome to TGN retrieval pathway. It has recently been shown that this is mediated by an alternative retromer pathway in which the sorting nexin SNX3 interacts with the cargo-selective subcomplex of the retromer to sort Wls into a retrieval pathway that is morphologically distinct from the classical SNX-BAR dependent retromer pathway. Here, we investigated how sorting of Wls between the two different retromer pathways is specified. We found that when the function of the cargo-selective subcomplex of the retromer is partially disrupted, Wnt secretion can be restored by interfering with the maturation of late endosomes to lysosomes. This leads to an accumulation of Wls in late endosomes and facilitates the retrieval of Wls through a SNX-BAR dependent retromer pathway. Our results are consistent with a model in which spatial separation of the SNX3 and SNX-BAR retromer complexes along the endosomal maturation pathway as well as cargo-specific mechanisms contribute to the selective retrieval of Wls through the SNX3 retromer pathway.
