Sustained Wnt secretion requires the endosomal SNX3-retromer complex for endosome-to-trans-Golgi network transport of the internalised Wnt chaperone Wntless. Here the authors show that in both C. elegans and human cells, SNX3-retromer requires an evolutionary conserved membrane remodelling complex for Wntless sorting and Wnt secretion.
