Distinct activities of Scrib module proteins organize epithelial polarityby Khoury & Bilder

AND

Lgl cortical dynamics are independent of binding to the Scrib-Dlg complex but require Dlg-dependent restriction of aPKCby Ventura et al.

Getting the upper hand: recent preprints describe how Lgl can be resistant to the action of aPKC with the help of ‘friends’ in the basolateral domain, whilst allowing aPKC to remain the dominant force apically.
