GABA-A receptor complex

Definition

Target type: cellularcomponent

A protein complex which is capable of GABA-A receptor activity. In human, it is usually composed of either two alpha, two beta and one gamma chain of the GABA-A receptor subunits or 5 chains of the GABA-A receptor subunits rho1-3 (formally known as GABA-C receptor). [GO_REF:0000088, GOC:bhm, GOC:TermGenie, PMID:18790874]

The GABA-A receptor complex, a pentameric ion channel responsible for mediating the inhibitory effects of the neurotransmitter GABA, is comprised of five subunits arranged in a circular fashion. Each subunit is a transmembrane protein with four transmembrane domains (TM1-TM4) and a large extracellular N-terminal domain. The subunit composition varies depending on the specific receptor subtype, but typically includes subunits from the α, β, γ, δ, ε, π, θ, and ρ families. The α subunit is essential for GABA binding, while the β subunit is crucial for channel gating. The γ subunit, which is often present, contributes to the assembly and trafficking of the receptor complex. The other subunits play modulatory roles, affecting receptor function and pharmacology. The transmembrane domains of the subunits form a central pore through which chloride ions can pass, leading to hyperpolarization of the neuronal membrane. The extracellular N-terminal domains of the subunits interact with each other and with other proteins, forming the binding sites for GABA and other modulators. The GABA-A receptor complex is located primarily at postsynaptic membranes of neurons, where it plays a critical role in neuronal inhibition. Its function is influenced by a wide range of factors, including the subunit composition, phosphorylation state, and interaction with other proteins.'

strychninestrychnine : A monoterpenoid indole alkaloid that is strychnidine bearing a keto substituent at the 10-position.

Strychnine: An alkaloid found in the seeds of STRYCHNOS NUX-VOMICA. It is a competitive antagonist at glycine receptors and thus a convulsant. It has been used as an analeptic, in the treatment of nonketotic hyperglycinemia and sleep apnea, and as a rat poison.

cocainecocaine : A tropane alkaloid obtained from leaves of the South American shrub Erythroxylon coca.

Cocaine: An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.
