There was an error published in J. Cell Sci.130, 525-530.

Unfortunately, the diagram of the actin filament in the poster was accidentally reflected during the creation of the figure. As a result, the filament was illustrated as a left-handed rather than a right-handed F-actin helix in the original version of this article. The online version of the article has been corrected accordingly. This change has no impact on the concepts presented in this article.

The authors apologise to the readers for any confusion that this error might have caused.
