Colin Mclean. Using Probabilistic Clustering to help Identify Multiple Protein Instances in Static PPI Datasets. Functioning of synapses is governed by macromolecular complexes held together by protein-protein, protein-lipid and lipid-lipid interactions. In the Post-Synaptic Density (PSD) multi-protein complexes contain multiple core proteins, such as the scaffolding proteins: PSD-95, SHANK, SAPAP. Commonly used clustering techniques fail to capture the role of these important proteins, by placing each protein in only a single community. Probabilistic clustering techniques circumnavigate this problem by assigning a probability to each protein belonging to a community, allowing overlapping structure of the data. We have implemented a principled statistical approach, based on clustering edges between nodes, for finding overlapping communities in our static Protein-Protein Interaction (PPI) networks ...
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein that is a member of the Shank family of synaptic proteins that may function as molecular scaffolds in the postsynaptic density of excitatory synapses. Shank proteins contain multiple domains for protein-protein interaction, including ankyrin repeats, and an SH3 domain. This particular family member contains a PDZ domain, a consensus sequence for cortactin SH3 domain-binding peptides and a sterile alpha motif. The alternative splicing demonstrated in Shank genes has been suggested as a mechanism for regulating the molecular structure of Shank and the spectrum of Shank-interacting proteins in the postsynaptic densities of the adult and developing brain. Alterations in the encoded protein may be associated with susceptibility to autism spectrum disorder. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2014 ...

Understanding how proteins fold and bind is interesting since these processes are central to most biological activity. Protein folding and protein-protein interaction are by themselves very complex but using a good and robust system to study them could ease some of the hurdles.. In this thesis I have tried to answer some of the fundamental questions of protein folding and binding. I chose to work with PDZ domains, which are protein domains consisting of 90-100 amino acids. They are found in more than 400 human proteins and function mostly as protein-protein interaction units. These proteins are very stable, easy to express and purify and their folding reaction is reversible under most laboratory conditions.. I have characterized the interaction of PSD-95 PDZ3 domain with its putative ligand under different experimental conditions and found out that its binding kinetics is sensitive to salt and pH. I also demonstrated that the two conserved residues R318 and H372 in PDZ3 are responsible for the ...

Pre-synaptic kainate receptors play a very significant role in this form of long-term potentiation. The mossy fibres (MF) are axons of granule cells in the dendate gyrus of the hippocampal formation that project to the CA3 region of the hippocampus. The MF-CA3 synapse is unusual in that it contains multiple sites for the release of glutamate, each of which has a corresponding post-synaptic density (see animation). During basal transmission, there is a low probability that any one of these sites will release neurotransmitter. In addition, unlike synapses in the CA1 region, there are few NMDA receptors located within the PSD. LTP in this synapse is NMDA receptor-independent and must follow a different mechanism to those found in other hippocampal synapses (eg. CA3-CA1 synapses).. LY382884, an antagonist that is selective for GluK1 containing receptors, was shown to block the induction of NMDA receptor-independent LTP in CA3 hippocampal neurons (Mossy Fibre LTP or MF-LTP; Bortolotto et al, 1999), ...
SynGAP, a protein abundant at the postsynaptic density (PSD) of glutamatergic neurons, is known to modulate synaptic strength by regulating the incorporation of AMPA receptors at the synapse. Two isoforms of SynGAP, ?1 and ?2, which differ in their C-termini, have opposing effects on synaptic strength. In the present study, antibodies specific for SynGAP-?1 and SynGAP-?2 are used to compare the distribution patterns of the two isoforms at the postsynaptic density (PSD) under basal and excitatory conditions. Western immunoblotting shows enrichment of both isoforms in PSD fractions isolated from adult rat brain. Immunogold electron microscopy of rat hippocampal neuronal cultures shows similar distribution of both isoforms at the PSD, with a high density of immunolabel within the PSD core under basal conditions. Application of NMDA promotes movement of SynGAP-?1 as well as SynGAP-?2 out of the PSD core. In isolated PSDs both isoforms of SynGAP can be phosphorylated upon activation of the endogenous ...

Alterations of glutamatergic synapses and excitatory transmission have been found in various ASD models expressing mutant or deleted Shank family proteins (Bozdagi et al., 2010; Wang et al., 2011; Schmeisser et al., 2012; Won et al., 2012). In this study, we have uncovered that Shank3 deficiency leads to the selective loss of NMDAR function and membrane trafficking through a mechanism involving the actin cytoskeleton and key regulators of actin dynamics. Understanding the mechanism through which Shank3 controls NMDARs will provide insights into the role of Shank3 in regulating NMDAR-dependent cognitive processes, which will help to identify key components that can restore NMDAR functions and mental capabilities in ASD conditions.. Actin is highly enriched in dendritic spines. Since the majority of excitatory synapses in the mammalian CNS are formed on dendritic spines, the remodeling and stability of actin is crucial to the formation and maintenance of glutamatergic synapses during development ...

Mice lacking Kalirin-7 (Kal7KO), a Rho GDP/GTP exchange factor, self-administer cocaine at a higher rate than wildtype mice, and show an exaggerated locomotor response to experimenter-administered cocaine. Kal7, which localizes to post-synaptic densities at glutamatergic synapses, interacts directly with the GluN2B subunit of the N-methyl-d-aspartate (NMDA; GluN) receptor. Consistent with these observations, Kal7 plays an essential role in NMDA receptor dependent long term potentiation and depression, and glutamatergic transmission plays a key role in the response to chronic cocaine. A number of genetic studies have implicated altered Kalirin expression in schizophrenia and other disorders such as Alzheimers Disease. A comparison of the effects of experimenter-administered cocaine on mice lacking all Kalirin isoforms to its effects on mice lacking only Kalirin-7 identified Kal7 as the key isoform whose deletion produces exaggerated locomotor responses to cocaine. Pretreatment of Kal7KO mice with a low
Alzheimers disease (AD) is characterised by neuropathological deposits of amyloid plaques and neurofibrillary tangles. In AD, tau is abnormally phosphorylated and forms aggregates which spread trans-synaptically throughout the brain. The non-receptor-associated tyrosine kinase fyn is up-regulated in a subset of tangle-bearing neurons in AD brain and fyn also phosphorylates tau. Most tau is axonally located, where it promotes microtubule stability. Both tau and fyn are found in dendrites, where they stabilise receptor complexes at the post-synaptic density. Tau is also trafficked to the plasma membrane in a phosphorylation-dependent process that requires fyn. Tau is also present in the extracellular space, which could play an important role in the spread of tau pathology in AD. The function of tau at the membrane, and the precise role of fyn in tau trafficking are unclear, but they suggest that fyn could contribute to tau propagation. Here, the role of fyn in tau release was investigated in ...

The sst2A diffuses rapidly within the plasma membrane as demonstrated using FRAP analysis of fluorescently tagged receptors. In addition, the percentage of the mobile fraction is very high (,85%) in the three cellular compartments studied. The diffusion characteristics of the sst2A is similar from those reported for other GPCRs in extrasynaptic sites, such as the serotonin 5HT1A (Pucadyil and Chattopadhyay, 2007) and dopamine D1 (Scott et al., 2006) receptors. In spines, although the sst2A receptor has been shown to potentially interact with scaffolding proteins of the postsynaptic density Shank1 and ProSAP1/CortBP1 (Zitzer et al., 1999a,b), our results indicate that, in resting conditions, only a minor portion of sst2A receptors might be associated with cytoskeletal anchoring proteins. However, such interactions often occur when the receptor is stimulated, as previously demonstrated for the sst2A and ProSAP1/CortBP1 (Zitzer et al., 1999a) or for the β-adrenergic receptor and the PDZ ...
