Loss or over-expression of Grainyhead-like transcription factors (Grhl) prevents closure of the neural tube but the mechanism underlying this is unclear. Here, the authors show that Grhl2 regulates murine posterior-neuropore closure via changes in the identity and biomechanics of the non-neural, surface ectoderm cells.
