There was an error published in J. Cell Sci. 122, 114-125.
In the left-hand panel of Fig. 7C (left), the control condition at 37°C was mistakenly shown with an example at 25°C. This error is corrected below with a new Fig. 7C (left) showing the control 37°C condition. The figure legend, results and interpretation for this work have not been altered in any way.
The corresponding author apologizes for this error.
