In the version of this article initially published, a panel in Extended Data Fig. 5a(H) was incorrect due to a figure preparation error. Briefly, the experiments were performed in 96-well plates and images of the control (DMSO-COLV) and treatment conditions were saved in separate folders. During figure assembly in InDesign the panel labeled “Obtustatin-COLV” was inadvertently associated with an image corresponding to “7rh-COLV.” Due to the age of the article, the figure cannot be updated directly. The revised figure is available as Supplementary Information accompanying this amendment. This notice serves to update the article.

Since all treatments were compared to the same DMSO-COLV control condition and no differences were observed between treated conditions this error has no impact on the results or their interpretation.

Supplementary information is available in the online version of this amendment.
