RNA editing of brain glutamate receptor channels: mechanism and physiology 1 Published on the World Wide Web on 5 February 1998. 1
Control of kinetic properties of AMPA receptor channels by nuclear RNA editing.
TLDR
Site-selective nuclear RNA editing controls the calcium permeability of AMPA receptor channels, and RNA editing at a second site is shown here to affect the kinetic aspects of these channels in rat brain.
Molecular biology of glutamate receptors
Extent of RNA editing of glutamate receptor subunit GluR5 in different brain regions of the rat
TLDR
The extent of RNA editing of glutamate receptor subunits may play an important role in the control of calcium fluxes through non-N-methyl-D-aspartate receptor channels in different physiological and/or pathological states of the brain.
RNA editing of a human glutamate receptor subunit.
Editing of neurotransmitter receptor and ion channel RNAs in the nervous system.
TLDR
This work has shown that the post-transcriptional conversion of adenosine to inosine (A-to-I) by RNA editing can dramatically expand the diversity of the transcriptome to generate multiple, functionally distinct protein isoforms from a single genomic locus.
Genetic manipulation of key determinants of ion flow in glutamate receptor channels in the mouse
Subunit composition at the single-cell level explains functional properties of a glutamate-gated channel
Candidate editases for GluR channels in single neurons of rat hippocampus and cerebellum
A-to-I RNA editing modulates the pharmacology of neuronal ion channels and receptors
TLDR
This review summarizes that RNA editing of several neuronal receptors and channels does not only change protein function, but also the pharmacology and presumably the drug therapy in human diseases.

TLDR
These results identify a switch in the molecular and functional properties of glutamate receptors operated by alternative splicing.
Structural determinants of ion flow through recombinant glutamate receptor channels
TLDR
The properties of heteromeric wild-type and mutant GluRs revealed that the dominance of GluR-B is due to the arginine residue in the TM2 region, and the steady-state current-voltage relations of glutamate- and kainate-induced currents through homomeric channels fell into two classes.

TLDR
The murine chromosomal gene for the GABAA receptor delta subunit was isolated and characterized by high-resolution mapping and DNA sequencing and displays an intron pattern comparable, but not identical, to that seen in members of the nicotinic acetylcholine receptor family.
