    ..Furthermore, the C-terminal PDZ-binding motif of Vangl2 is required for localization to dendritic spines. These results suggest that Vangl2 is a new component of the PSD that forms a complex with PSD-95 in the adult brain. ..

    ..The study provides an unbiased view of key genes and proteins that act as gender dependent molecular sensors. The disruption of their expression by adverse early life stress may explain the alterations that occur in behavior. ..
