1.

postsynaptic membrane

A specialized area of membrane facing the presynaptic membrane on the tip of the nerve ending and separated from it by a minute cleft (the synaptic cleft). Neurotransmitters cross the synaptic cleft and transmit the signal to the postsynaptic membrane. Synonym: post-synaptic memb...

dendritic spine

A small, membranous protrusion from a dendrite that forms a postsynaptic compartment - typically receiving input from a single presynapse. They function as partially isolated biochemical and an electrical compartments. Spine morphology is variable including "thin", "stubby", "mushroom",...

negative regulation of GTPase activity

Any process that stops or reduces the rate of GTP hydrolysis by a GTPase. Synonyms: GO:0034259; GO:0034261; GO:1902264; GO:1902881; down regulation of GTPase activity; down regulation of Rab GTPase activity; down regulation of Ras GTPase activity; down regulation of Rho GTPase activity;...

postsynaptic density

An electron dense network of proteins within and adjacent to the postsynaptic membrane in asymetric synapses. Its major components include neurotransmitter receptors and the proteins that spatially and functionally organize them such as anchoring and scaffolding molecules, signaling...

regulation of G-protein coupled receptor protein signaling pathway

Any process that modulates the frequency, rate or extent of G-protein coupled receptor protein signaling pathway activity. Synonyms: regulation of G protein coupled receptor protein signaling pathway; regulation of G protein coupled receptor protein signalling pathway; regulation...

6.

G-protein coupled receptor signaling pathway

A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further...
