Proteins of the ProSAP/Shank family act as major organizing scaffolding elements within the postsynaptic density of excitatory synapses. Deletions, mutations or the downregulation of these molecules has been linked to autism spectrum disorders, the related Phelan McDermid Syndrome or Alzheimer's disease. ProSAP/Shank proteins are targeted to synapses(More)
The majority of neurons within the central nervous system receive their excitatory inputs via small, actin-rich protrusions called dendritic spines. Spines can undergo rapid morphological alterations according to synaptic activity. This mechanism is implicated in learning and memory formation as it is ultimately altering the number and distribution of(More)
Recently, mutations in ProSAP2/Shank3 have been discovered as one of the genetic factors for schizophrenia (SCZ). Here, we show that the postsynaptic density protein ProSAP2/Shank3 undergoes activity dependent synapse-to-nucleus shuttling in hippocampal neurons. Our study shows that the de novo mutation (R1117X) in ProSAP2/Shank3 that was identified in a(More)
