Polarity-deficient epithelial cells are eliminated through Sas-Ptp10D-mediated suppression of EGFR signalling during cell competition. Here the authors show the constitutively active, phosphomimetic WASH can activate both EGFR and Hippo signalling and thereby, induces the overgrowth of these polarity-deficient cells in Drosophila and in proliferating epithelial cells, WASH activation differentially affects the separate recycling routes of EGFR and its inhibitor Ptp10D.
