Postsynaptic ProSAP/Shank scaffolds in the cross-hair of synaptopathies

Grabrucker, Andreas M., Schmeisser, Michael J., Schoen, Michael, Boeckers, Tobias M.·2011·Trends in Cell Biology

Abstract

Intact synaptic homeostasis is a fundamental prerequisite for a healthy brain. Thus, it is not surprising that altered synaptic morphology and function are involved in the molecular pathogenesis of so-called synaptopathies including autism, schizophrenia (SCZ) and Alzheimer's disease (AD). Intriguingly, various recent studies revealed a crucial role of postsynaptic ProSAP/Shank scaffold proteins in all of the aforementioned disorders. Considering these findings, we follow the hypothesis that ProSAP/Shank proteins are key regulators of synaptic development and plasticity with clear-cut isoform-specific roles. We thus propose a model where ProSAP/Shank proteins are in the center of a postsynaptic signaling pathway that is disrupted in several neuropsychiatric disorders.

  • SHANK genes code for large synaptic scaffold proteins of the post-synaptic density.

    “Here, we focused on the three SHANK genes, which code for large synaptic scaffold proteins of the post-synaptic density [12].”
  • It has been proposed that abnormal SHANK levels at the synapse might result in the mislocalization, de-clustering and/or functional impairment of several other crucial synaptic proteins such as cytoskeletal regulators and/or neurotransmitter receptors.

    “It has been proposed that abnormal SHANK levels at the synapse might result in the mislocalization, de-clustering and/or functional impairment of several other crucial synaptic proteins such as cytoskeletal regulators and/or neurotransmitter receptors [12] (Table 3).”
  • Research into the pathogenesis of ASD has largely focused on understanding unifying biochemical mechanisms based on the hypothesis that ASD is a 'synaptopathy'.

    “For more than a decade, research into the pathogenesis of ASD has largely focused on understanding unifying biochemical mechanisms based on the hypothesis that ASD is a ‘synaptopathy’ (Bear et al., 2008; Dölen and Bear, 2009; Grabrucker et al., 2011).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
