Correction to: Communications Biology https://doi.org/10.1038/s42003-018-0017-7, published online 22 February 2018.

The original published version of the paper contained labelling errors in Figures 1 and 5. The x-axis of Figure 1e was incorrectly labelled as “Receptors . μm2” instead of “Receptors . μm−2”. The figure key in Figure 5b incorrectly labelled the blue circles as “Wild-type” and the purple circles as “+m-ephrinA1”. The correct labels are blue: “Wild-type+m-ephrinA1” and purple: “Wild-type, no ligand.” The original version also contained a typesetting error in Table 1. The values in the second row, rightmost column, were not all set in bold text as required. The errors do not impact the conclusions in the main text of the paper. These errors have been corrected in the PDF and HTML versions of the paper.
