Abstract
The apical–basal polarity of epithelial cells depends on mutual antagonism between the apical aPKC and lateral LGL proteins. Until now, it has been unclear how LGL can be both a substrate and inhibitor of aPKC. Now, a cryo-electron microscopy (cryo-EM) structure of a stalled PAR6–aPKC–LGL complex addresses this conundrum.
