Positive relationship network of GABBR2 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_21340	gpcr ligand_binding	There are more than 800 G-protein coupled receptor. GPCRs ar...... There are more than 800 G-protein coupled receptor. GPCRs are receptors for a diverse range of ligands from large proteins to photons and have an equal diverstiy of ligand-binding mechanisms. Classical GPCR signaling involves signal transduction via heterotrimeric G-proteins, however many G-protein independent mechanisms have been reported. More...
REACT_19184	downstream events_in_gpcr_signaling	G protein-coupled receptors. The beta:gamma G-protein dimer ...... G protein-coupled receptors. The beta:gamma G-protein dimer is also involved in downstream signaling , and some receptors form part of metastable complexes of receptor and accessory proteins such as the arrestins. GPCRs are involved in many diverse signaling events , using a variety of pathways that include modulation of adenylyl cyclase, phospholipase C, the mitogen activated protein kinases (MAPKs), extracellular signal regulated kinase (ERK) c-Jun-NH2-terminal kinase (JNK) and p38 MAPK. More...

The classical signalling mechanism for G alpha (i) is inhibition of the cAMP dependent pathway through inhibition of adenylate cyclase. Decreased production of cAMP from ATP results in decreased activity of cAMP-dependent protein kinases. More...

The class C G-protein-coupled receptors are a class of G-protein coupled receptors that include the metabotropic glutamate receptors and several additional receptors. Family C GPCRs have a large extracellular N-terminus which binds the orthosteric (endogenous) ligand. The shape of this domain is often likened to a clam. Several allosteric ligands to these receptors have been identified and these bind within the seven transmembrane region. More...
