Endosomal trafficking has been implicated in several neurodevelopmental disorders including Rett Syndrome (RTT) and Schizophrenia (SZ). Endosomal proteins
have been identified in genomic studies in both disorders, suggesting a common molecular mechanism. To characterize endosomal proteins in these disorders,
we analyzed protein expression in the cortex and dentate gyrus of the hippocampus as well as in synaptosome preparations from whole-brain lysates. Immunofluorescent staining demonstrated alterations in key endosomal proteins in coronal brain sections from Mecp2
deficient mice and BLOC-1 deficient mice in the cortex and hippocampus. In addition, biochemical analysis of whole-brain homogenate and synaptosome fractions
demonstrated an alteration in endosomal markers. Neurite outgrowth was also significantly decreased in PC12 cells lacking dysbindin and Mecp2. Lastly, to
