Holes in endothelial barriers, called transendothelial cell macroapertures (TEMs), are predicted to be limited by line tension of unknown origin. Here the authors identify an actomyosin cable encircling TEMs and establish a role for ezrin in stabilising F-actin bundles, allowing their crosslinking by non-muscle myosin IIa.
