Adenosine deaminase, RNA-specific, B1

RED1, ADAR2, RNA editing enzyme
This gene encodes the enzyme responsible for pre-mRNA editing of the glutamate receptor subunit B by site-specific deamination of adenosines. Studies in rat found that this enzyme acted on its own pre-mRNA molecules to convert an AA dinucleotide to an AI dinucleotide which resulted in a new splice site. Alternative splicing of this gene results in several transcript variants, some of which have been characterized by the presence or absence of an ALU cassette insert and a short or long C-terminal region.

We have demonstrated up-regulation and editing of astrocytic genes for ADAR2, the kainate receptor GluK2, cPLA2 and the 5-HT2B receptor itself after chronic treatment of cultures, which do not express SERT and after treatment of mice (expressing SERT) for 2 weeks with fluoxetine, followed by isolation of astrocytic and neuronal cell fractionation.

AGS-causing mutations have also been found in the genes of the 3'-exonuclease TREX1, the dNTP triphosphatase SAMHD1, as well as the RNA-editing enzyme ADAR1, defining defects in nucleic acid metabolism pathways as a common hallmark of AGS pathology.
