ErbB-2/
HER2
drives epithelial malignancies by forming heterodimers with growth factor receptors. The primordial invertebrate receptor is sorted to the basolateral epithelial surface by binding of the PDZ domain of Lin-7 to the receptor's tail. We show that all four human ErbBs are basolaterally expressed, even when the tail motif is absent. Mutagenesis of
hLin-7
unveiled a second domain, KID, that binds to the kinase region of ErbBs. The PDZ interaction mediates stabilization of ErbB-2 at the basolateral surface. On the other hand, binding of KID is involved in initial delivery to the basolateral surface, and in its absence, unprocessed ErbB-2 molecules are diverted to the apical surface. Hence, distinct domains of Lin-7 regulate receptor delivery to and maintenance at the basolateral surface of epithelia.
