human kainate receptor GluR7 gene (GRIK3)	Schiffer, 2007	patients and normal controls	P-value=0.0012	We detected a significant linkage disequilibrium (LD) indica...... We detected a significant linkage disequilibrium (LD) indicated by preferential maternal transmission of the GluR7 S310 allele to R-MDD patients (P = 0.012), but not to bipolar I disorder (BPI) patients (P = 1.00). We performed a second independent study by applying the TDT in 81 parent-offspring triads from families that inherit recurrent early-onset major depressive disorder (RE-MDD). The results from this second study showed only a suggestive maternal association (P = 0.068). More...

Positive relationship network of GRIK3 in MK4MDD

Network loading ...

Note:
1. The different color of the nodes denotes the level of the nodes.

Genetic/Epigenetic Locus	Protein and Other Molecule	Cell and Molecular Pathway	Neural System	Cognition and Behavior	Symptoms and Signs	Environment	MDD

2. Besides the component related relationships from literature, gene mapped protein and protein mapped gene are also shown in the network. If the mapped gene or protein is not from literature, square node would be used instead of Circle node. Accordingly, the relationship is marked with dot line.
2. User can drag the nodes to rearrange the layout of the network. Click the node will enter the report page of the node. Right-click will show also the menus to link to the report page of the node and remove the node and related edges. Hover the node will show the level of the node and hover the edge will show the evidence/description of the edge.
3. The network is generated using Cytoscape Web

REACT_21312	activation of_kainate_receptors_upon_glutamate_binding	Kainate receptors are found both in the presynaptc terminals...... Kainate receptors are found both in the presynaptc terminals and the postsynaptic neurons. Kainate receptor activation could lead to either ionotropic activity (influx of Ca2+ or Na+ and K+) in the postsynaptic neuron or coupling of the receptor with G proteins in the presynaptic and the postsynaptic neurons. Kainate receptors are tetramers made from subunits GRIK1-5 or GluR5-7 and KA1-2. Activation of kainate receptors made from GRIK1 or KA2 release Ca2+ from the intracellular stores in a G protein-dependent manner. The G protein involved in this process is sensitive to pertussis toxin. More...
REACT_21322	ionotropic activity_of_kainate_receptors	Kainate receptors are either Ca2+ permeable or impermeable d...... Kainate receptors are either Ca2+ permeable or impermeable depending on the composition of the receptor and the editing status of subunits GluR5 and GluR6 (GRIK1 and 2). More...
REACT_15370	neuroransmitter receptor_binding_and_downstream_transmission_in_the_postsynaptic_cell	The neurotransmitter in the synaptic cleft released by the p...... The neurotransmitter in the synaptic cleft released by the pre-synaptic neuron binds specific receptors located on the post-synaptic terminal. These receptors are either ion channels or G protein coupled receptors that function to transmit the signals from the post-synaptic membrane to the cell body. More...
REACT_13477	transmission across_chemical_synapses	Chemical synapses are specialized junctions that are used fo...... Chemical synapses are specialized junctions that are used for communication between neurons, neurons and muscle or gland cells. The synapse involves a pre-synaptic neuron and a post-synaptic neuron, muscle cell or glad cell. The pre and the post-synaptic cell are separated by a gap of 20nm called the synaptic cleft. The signals pass in a unidirection from pre-synaptic to post-synaptic. The pre-synaptic neuron communicates via the release of neurotransmitter which bind the receptors on the post-synaptic cell.
