Instructive role of aPKCzeta subcellular localization in the assembly of adherens junctions in neural progenitors.

ABSTRACT: In the neurogenic phase of CNS development, the proliferating progenitors are found medially within the neuroepithelium. The adherens junctions on the apical membrane of proliferating neural progenitors allow for cell-cell adhesion and medial stratification. In contrast, differentiating neuronal precursors delaminate and migrate laterally, establishing the laminar layers. Apical adherens junctions also establish the apical-basal polarity in neural progenitors, which in turn is postulated to lead to asymmetric inheritance of cell fate determinants during neurogenic divisions. The signaling pathways and cellular mechanisms that regulate the assembly and asymmetric localization of adherens junctions in neural progenitors remain elusive. Here we show that atypical PKCzeta/lambda (aPKCzeta/lamb
