Structural analysis reveals a two-step EB1-SxIP binding mechanism and identifies ligand mutations that greatly enhance affinity, offering potential therapeutic avenues for targeting microtubule plus end interactions.
Quantitative Drosophila pupal wing experiments support planar polarity depending on cell-scale signalling that does not involve depletion of a limited pool of core proteins or polarised transport on microtubules.
