- Activation of G protein gated Potassium channels, organism-specific biosystem (from REACTOME)
Activation of G protein gated Potassium channels, organism-specific biosystemActivation of Kir 3 channels occurs after binding of G beta gamma subunits of GPCR. Activation of Kir3/GIRK leads to K+ efflux. The dissociation of GPCR into G alpha and G beta gamma subunits is acti...
- Activation of GABAB receptors, organism-specific biosystem (from REACTOME)
Activation of GABAB receptors, organism-specific biosystemGABA B receptors are metabotropic receptors that are functionally linked to C type G protein coupled receptors.? GABA B receptors are activated upon ligand binding. The GABA B1 subunit binds ligand a...
- Cholinergic synapse, organism-specific biosystem (from KEGG)
Cholinergic synapse, organism-specific biosystemAcetylcholine (ACh) is a neurotransmitter widely distributed in the central (and also peripheral, autonomic and enteric) nervous system (CNS). In the CNS, ACh facilitates many functions, such as lear...
- Classical Kir channels, organism-specific biosystem (from REACTOME)
Classical Kir channels, organism-specific biosystemClassical Kir channels are inwardly rectifying K+ channels with strong inwardly rectifying currents that contribute to highly negative resting membrane potential, prolonged action potential plateau a...
- G protein gated Potassium channels, organism-specific biosystem (from REACTOME)
G protein gated Potassium channels, organism-specific biosystemInwardly rectifying G protein activated K+ channels (GIRK) are tetrameric assemblies of Ki3 3 family subunits (Kir 3.1, 3.2 3.3 and 3.4). The activation of G protein coupled receptor by ligand result...
- GABA B receptor activation, organism-specific biosystem (from REACTOME)
GABA B receptor activation, organism-specific biosystemFunctional GABA B receptors are heteromers of GABA B1 and B2 subunits, complexed with G protein alpha-i, 0, beta, and gamma subunits. They function as metabotropic receptors. When GABA is bound to th...
- GABA receptor activation, organism-specific biosystem (from REACTOME)
GABA receptor activation, organism-specific biosystemGamma aminobutyric acid (GABA) receptors are the major inhibitory receptors in human synapses. They are of two types. GABA A receptors are fast-acting ligand gated chloride ion channels that mediate ...
- Inhibition of voltage gated Ca2+ channels via Gbeta/gamma subunits, organism-specific biosystem (from REACTOME)
Inhibition of voltage gated Ca2+ channels via Gbeta/gamma subunits, organism-specific biosystemGABA B receptors are coupled to Gproteins and function by increasing the K+ and decreasing the Ca2+ inside the cell. The increase in K+ increases the negative membrane potential of the cell thereby h...
- Inwardly rectifying K+ channels, organism-specific biosystem (from REACTOME)
Inwardly rectifying K+ channels, organism-specific biosystemInwardly rectifying K+ channels (Kir channels) show an inward rather than outward (like the voltage gated K+ channels) flow of K+ thereby contributing to maintenance of resting membrane potential an...
- Neuronal System, organism-specific biosystem (from REACTOME)
Neuronal System, organism-specific biosystemThe human brain contains at least 100 billion neurons, each with the ability to influence many other cells. Clearly, highly sophisticated and efficient mechanisms are needed to enable communication a...
- Neurotransmitter Receptor Binding And Downstream Transmission In The Postsynaptic Cell, organism-specific biosystem (from REACTOME)
Neurotransmitter Receptor Binding And Downstream Transmission In The Postsynaptic Cell, organism-specific biosystemThe 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 cou...
- Potassium Channels, organism-specific biosystem (from REACTOME)
Potassium Channels, organism-specific biosystemPotassium channels are tetrameric ion channels that are widely distributed and are found in all cell types. Potassium channels control resting membrane potential in neurons, contribute to regulation ...
- Transmission across Chemical Synapses, organism-specific biosystem (from REACTOME)
Transmission across Chemical Synapses, organism-specific biosystemChemical 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,...
