Mutations in the putative glutamatergic synapse scaffolding protein SAP97 are associated with the development of schizophrenia in humans. However, the role of SAP97 in synaptic regulation is unclear. Here we show that SAP97 is expressed in the dendrites of granule neurons in the dentate gyrus but not in the dendrites of other hippocampal neurons. Schizophrenia-related perturbations of SAP97 did not affect CA1 pyramidal neuron synapse function. Conversely, these perturbations produce dramatic…

4.1N and SAP97 regulate different phases of AMPA receptor intracellular transport

This work analyzes how interactions between GluA1 and 4.1N or SAP97 regulate IT and exocytosis at the plasma membrane in basal condition and after cLTP induction to identify the differential roles of 4.

Tiam1 is Critical for Glutamatergic Synapse Structure and Function in the Hippocampus

It is found that Tiam1 plays a critical role in the development of glutamatergic perforant path–dentate gyrussynapses, but not in commonly studied in Schaffer collateral–CA1 synapses, and this investigation investigates the synaptic regulatory role of the RhoGEF protein Tiam 1, whose expression appears to be remarkably enriched in granule neurons of the dentate g Cyrus.

Dynamic SAP102 expression in the hippocampal subregions of rats and APP/PS1 mice of various ages

Fundamental data is provided to support the functional differences of SAP102 in different hippocampal subregions during postnatal periods and may serve as the basis for additional functional studies on SAP 102 in normal physiological conditions and different stages of AD.

The role of SAP97 in synaptic glutamate receptor dynamics

Results support the hypothesis that SAP97 is part of the machinery that traffics glutamate receptors and compensates for other PSD-MAGUKs in knockout mouse models, due to functional redundancy.

The hippocampal formation in schizophrenia.

A postmortem molecular changes suggest a selective reduction in glutamate transmission in the dentate gyrus and in its efferent fibers, the mossy fiber pathway, which could result in a resulting increase in "runaway" CA3-mediated pattern completion, generating psychotic associations and resulting in memories with psychotic content.

Synapse-Associated Protein-97 Isoform-Specific Regulation of Surface AMPA Receptors and Synaptic Function in Cultured Neurons

It is found that recombinant SAP97 not only becomes concentrated at synaptic junctions but also leads to an increase in synaptic AMPA receptors, spine enlargement, and an increased in miniature EPSC frequency, indicating that SAP97 has both postsynaptic and presynaptic effects on synaptic transmission.

Synaptic SAP97 Isoforms Regulate AMPA Receptor Dynamics and Access to Presynaptic Glutamate

Results indicate that N-terminal splicing of SAP97 can control synaptic strength by regulating the distribution of AMPARs and, hence, their responsiveness to presynaptically released glutamate.

Synapse-Associated Protein 102/dlgh3 Couples the NMDA Receptor to Specific Plasticity Pathways and Learning Strategies

In vivo data support the model that specific MAGUK proteins couple the NMDA receptor to distinct downstream signaling pathways that provide a mechanism for discriminating patterns of synaptic activity that lead to long-lasting changes in synaptic strength as well as distinct aspects of cognition in the mammalian nervous system.

Selective reduction of a PDZ protein, SAP‐97, in the prefrontal cortex of patients with chronic schizophrenia

Findings suggest that a phenotypic loss of SAP97 is associated with the postsynaptic impairment in prefrontal excitatory circuits of schizophrenic patients.

SAP97 directs NMDA receptor spine targeting and synaptic plasticity

Examination of whether SAP97 isoforms regulate the mechanisms underlying long‐term potentiation (LTP) and depression (LTD) and find that both α‐ and β‐forms of SAP97 impair LTP but enhance LTD via independent isoform‐specific mechanisms.
